■Overview
Technology development of the AS-Interface
System limits of the AS-Interface Specification
Expansions of the AS-Interface Specification 2.1
• The AS-Interface Specification 2.1 enables the number of net-
work stations to be doubled from 31 to 62.The 31 addresses
which are possible in an AS-Interface network can be split by
means of the so-called extended addressing function.
• If this option is used for each of the 31 slaves, the maximum
number of stations in an AS-Interface network is then 62. The
so-called A/B slaves can have a maximum of four inputs and
three outputs. The extended addressing function can be used
only for digital slaves, not for analog slaves or safety-oriented
slaves (ASIsafe).
• Another function of the AS-Interface Specification V2.1 is the
integrated analog value transfer function. In this case "inte-
grated" means that no special function blocks are required for
accessing the analog values. It is just as easy to access the
analog values as the digital values. The integrated analog
value transfer function can be used with analog slaves which
support the profiles 7.3 and 7.4.
Expansions of the AS-Interface Specification 3.0
• The AS-Interface Specification 3.0 enables the connection of
up to 1000 digital inputs and outputs (profile S-7.A.A: 8DI/8DO
as A/B slave).
• New profiles make it possible to use the extended addressing
function for analog slaves as well.
• Analog value transfer is accelerated by "Fast Analog Profiles".
• Variable use of analog modules: optional parameterization of
the resolution (12/14 bit) and one or two channels.
• Asynchronous serial protocol 100 baud or 50 baud bidirec-
tional.

AS-Interface master
To be able to operate A/B slaves on an AS-Interface network you
must also use master modules which comply with at least
Specification 2.1.
A/B technology is supported by the masters of the SIMATIC S7
and the DP/AS-Interface links from Siemens. Only standard
slaves and A slaves (= A/B slave with an A address) can be
operated on masters which do not support Specification 2.1.
The subaddress of A/B slaves is set to "A" in the as-delivered
state.
The new masters according to Specification 3.0 support all new
slave profiles and also display full download compatibility.
The AS-Interface Specification applicable for the particular slave
is specified in the section Selection and Ordering Data.
The exact slave profile is shown in the section
Technical Specifications.
Communication cycle
Standard slaves are queried in each cycle (max. cycle time:
5 ms). If only one A or B slave is installed at an address, this
slave will be queried in each cycle (max. cycle time: 5 ms). If an
A/B slave pair is installed at an address, the A slave will be que-
ried in one cycle and the B slave in the next cycle (max. cycle
time: 10 ms). If only standard and/or A slaves are installed in a
network, the cycle time is identical to the standard masters
(max. cycle time: 5 ms).
Whether an AS-Interface slave is a standard slave or an A/B
slave is noted in the section Selection and Ordering Data in the
column Slave Type and can be deduced from the section
Technical Specifications of the slave in question.
All slave types can be mixed and used in the same AS-Interface
network.
■Benefits
• Reduction of master and power supply costs thanks to a
higher number of slaves and I/Os per AS-Interface line.
• Improved decentralization in plants with numerous, widely
spread signals.
• Further expansion of existing AS-Interface systems is
possible.

■Overview
• Compact router between PROFIBUS (DP Slave) and
AS-Interface
• Single and double AS-Interface master (according to
AS-Interface Specification V3.0) for connection of
62 AS-Interface slaves each and integrated analog value
transfer
• Integrated ground fault monitoring for the AS-Interface cable
• User-friendly local diagnostics and start-up by means of a full
graphic display and control keys or through a web interface
with a standard browser
• Optimum TIA integration through STEP 7, integration in non-
Siemens engineering tools using PROFIBUS type file (GSD)
• Vertical integration (standard web interface) through Industrial
Ethernet
• Supply from AS-Interface cable; hence no additional power
supply required
• Module exchange without a PG using C-PLUG
■Benefits
• Short start-up times through simple configuration at the press
of a button and testing of the AS-Interface line using the
display or web interface
• Reduction of downtimes and servicing times in the event of a
slave failure thanks to user-friendly diagnostics using the
display or web interface and through simple module
exchange with the help of the C-PLUG exchange medium
• Reduction of installation costs because the supply comes
completely from the AS-Interface cable, making an additional
power supply superfluous
• Reduced amount of engineering work thanks to user-friendly
configuration of Siemens slaves using the slave catalog in
HW-Config (STEP 7)
• Costs saved by the double AS-Interface master when large
volumes of project data are involved

■Application
The DP/AS-i LINK Advanced is a PROFIBUS DPV1 slave
(according to EN 50 170) and an AS-Interface master (based on
AS-Interface Specification V3.0 according to EN 50 295).
It enables transparent data access to AS-Interface from
PROFIBUS DP.
PROFIBUS DP masters can exchange I/O data with AS-Interface
in cyclic mode; DP masters with acyclic services can perform
AS-Interface master calls in addition. As such, the DP/AS-i LINK
Advanced is particularly well suited for a decentral construction
and for connection of a lower-level AS-Interface network.
For applications with typical volumes of project data it is
sufficient to use the DP/AS-i LINK Advanced in its version as an
AS-Interface single master.
For applications with large volumes of project data
the DP/AS-i LINK Advanced in its version as an AS-Interface
double master is used. In this case, twice the volume of project
data can be used on two AS-Interface lines running indepen-
dently of each other.

■Overview
The new AS-Interface Specification 3.0 adds a number of com-
pletely new features to AS-Interface bus system. The extended
address mode (A/B addresses) enables the connection of up to
62 slaves on one AS-Interface network. With the extended
address mode according to Specification 3.0, four outputs are
now possible for the first time even with A/B slaves (instead of
only three outputs possible up to now with Specification 2.1).
Hence with full expansion of an AS-Interface network, there are
now 248 inputs as well as 248 outputs available on one
AS-Interface system.
Modules with four inputs and four outputs as A/B slaves
according to Specification 3.0 are available
• for field use in degree of protection IP67 (compact modules
K20 and K60)
• and for the control cabinet (SlimLine Module S45) in degree of
protection IP20.
Please note that these modules can be used only with a new
master according to AS-Interface Specification 3.0 (e.g. the new
DP/AS-i LINK Advanced) and that the cycle times for the outputs
can extend to max. 20 ms.

■Overview
The K20 series of compact modules supplements the
AS-Interface compact modules with a particularly narrow
version measuring just 20 mm wide. Thanks to their extremely
compact size the modules are particularly well suited for the use
of handling machines in production systems where modules
need to be arranged in most confined space. Another field of
application is robotics. The K20 modules are connected to the
AS-Interface with a round cable with M12 cable box instead of
with the AS-Interface flat cable. The AS-Interface bus cable and
the 24 V DC auxiliary power supply are routed in this case in a
shared round cable. This enables a mounting arrangement that
saves a great deal of space. Use on moving machinery is also
possible without difficulty thanks to the flexibility of the round
cable. The K20 modules are also ideal for such applications as
their non-encapsulated design makes them particularly light in
weight.
In applications with tow chains, many users rely on placing the
AS-Interface bus cable in a round cable. With the K20 modules,
direct connection to the round cable is possible in this case.
No adapter is required from the flat to the round cable.
The K20 series of compact modules includes both standard
AS-Interface modules as well as an ASIsafe version for connec-
tion of safety-oriented sensors such as Emergency Stop push-
buttons or door safety monitors. All standard AS-Interface
K20 modules support the extended address module (A/B
addresses) accorfding to AS-Interface Specification 2.1, with
which 62 stations can be connected to one AS-Interface net-
work. The K20 module with four inputs and four outputs works in
the extended address mode according to AS-Interface
Specification 3.0, thus enabling for the first time four outputs with
one A/B slave and hence 248 inputs plus 248 outputs with full
expansion of the AS-Interface network.
For particularly space-saving dimensions the sensors and actu-
ators are connected using M8 plug-in connectors. Alternatively
there is also an M12 socket with a Y connector.

Analog I/O modules, IP67 – K60
2
■Overview
AS-Interface analog modules from the K60 compact series
detect or issue analog signals locally. These modules are linked
to the higher level controller through an AS-Interface master
according to Specification 2.1 or Specification 3.0.
The analog modules are divided into five groups:
• Input module for sensors with current signal
• Input module for sensors with voltage signal
• Input module for sensors with thermal resistor
• Output module for current actuators
• Output module for voltage actuators
The input modules according to Profile 7.3/7.4 are available with
two or four input channels. It is possible in addition to convert the
two-channel module to using only one input channel, thus
enabling very short times before the analog value is available.
The conversion is effected by means of a jumper plug at
socket 3.The transmission times achieved with analog modules
according to Profile 7.A.9 are half shorter than those achieved
with Profile 7.3/7.4. Operation is adjustable in this case, e.g. it is
possible to choose with the ID1 Code whether the module is op-
erated with one or two channels.
The output modules are configured as two-channel modules as
standard.
The input and output channels are electrically isolated from the
AS-Interface network. If sensors with a higher power require-
ment are to be connected, more power can be supplied through
the auxiliary voltage as an alternative to the internal supply.
In the manual the modules are presented in great detail along
with their technical specifications and in-depth notes on opera-
tion. Sample function blocks round off the manual.
■Benefits
• Analog modules are just as easy to integrate in AS-Interface
as digital modules
• Analog values can be easily detected and issued locally
• Preprocessing of the analog value transmission in the master
enables rapid evaluation of the analog values
• Up to four values can be detected using one analog module
• Extremely fast transmission and conversion of analog values
is possible by the new possibility of changing over to single-
channel operation
Specification 3.0 now provides the following benefits in addition:
• A/B technology is now also available with analog modules
• On average the transmission times are shorter by half (only
three or four cycles depending on the resolution selected); the
total processing times can be found in the manual
• Operation is variably adjustable: 12 or 14-bit resolution, one or
two channels can be selected with the ID1 Code
• Handling of the analog value processing with masters
Specification 3.0, the DP/AS-i LINK Advanced, has been
further simplified

■Design
• Solid plastic enclosure in degree of protection IP20 for
standard rail mounting
• Compact design
- Display in the front panel for detailed indication of the
operating state and functional readiness of all connected
and activated AS-Interface slaves
- 6 buttons for starting up and testing the AS-Interface line
directly on DP/AS-i LINK Advanced
- LED indication of the operating state of PROFIBUS DP and
AS-Interface
- Integrated Ethernet port (RJ45 socket) for user-friendly
start-up, diagnostics and testing of the DP/AS-i LINK
Advanced through a web interface using a standard browser
- Supply voltage from the AS-Interface shaped cable or
alternatively through the 24 V DC supply
- Small mounting depth thanks to recessed plug mounting
• Simple mounting on standard rail
• Operation without fans and batteries
• Quick exchange of devices in the event of a fault when using
the optional C-PLUG exchange medium (not included in the
scope of supply)
■Function
The DP/AS-i LINK Advanced provides a PROFIBUS
DP master with the possibilities of cyclic access to the I/O data
of all the slaves of a lower-level AS-Interface segment.
According to the extended AS-Interface Specification (V3.0) it is
possible to connect a maximum of 62 slaves, each with 4 inputs
and 4 outputs and analog slaves, per AS-Interface line.
DP/AS-i LINK Advanced occupies in the master as standard
32 bytes of input data and 32 bytes of output data in which the
I/O data of the connected AS-Interface slaves are stored. The
size of the input/output buffer can be compressed so that only
the actually required I/O memory space is occupied in the
system of the DP master. The integrated evaluation of analog
signals is just as easy as access to digital values; there is no
need to call any communication modules.
PROFIBUS DP V1 masters are able in addition to initiate
AS-Interface master calls (e.g. to write parameters, change
addresses or read diagnostics values) through the acyclic
PROFIBUS services.
Using an operating display in AS-i Link it is possible to fully
commission the lower-level AS-Interface line.
The DP/AS-i LINK Advanced is equipped with an additional
Ethernet port which enables use of the integrated web server
and further increases the previously described user-friendliness
of the operating display. Free firmware updates are also
possible.
The optional C-PLUG supports module exchange without a PG,
thus reducing downtimes to a minimum in the event of a fault.
Diagnostics
With LEDs, the display and control keys, web interface and
STEP 7 there is an extensive diagnostics offering that includes:
• Operating state of the link
• State of the link as a PROFIBUS DP slave
• Diagnostics of the AS-Interface network
• Message frame statistics
• Standard diagnostics pages for fast diagnostics access using
a standard browser
Configuration
The configuration of the DP/AS-i LINK Advanced can be defined
either by means of STEP 7/NCM PC or simply by adopting the
ACTUAL configuration on the display.
Alternatively the DP/AS-i LINK Advanced can be integrated
through the PROFIBUS type file (GSD) in the engineering tool:
• COM PROFIBUS
• Older STEP 7/NCM PC versions
• Non-Siemens engineering tools
With STEP 7 configuring, the AS-Interface configuration can be
uploaded in STEP 7 V5.4 and higher. The user-friendly configu-
ration of AS-Interface slaves from Siemens is also possible here
in HW-Config (slave catalog).

Installation
Mounting the K20 modules: on the front (see left) or on the side (see right)
The K20 modules are mounted with two screws. A mounting
plate is not required. In addition to mounting in the front it is
possible to mount the modules on the side in a space-saving
and protected position, e.g. on mounting rails.
Addressing
Addressing the K20 modules
Addressing the K20 modules is performed using the same
socket as for the bus connection. For the addressing the module
is connected to the 3RK1 904-2AB01 addressing unit using a
standard M12 cable (2 or 3-pole), e.g. 3RX8 000-0GF32-1AB5.
If the older version of the 3RK1 904-2AB00 addressing unit is
used, a special addressing cable (3RK1 901-3RA00) is required
for connection to the addressing unit. After the addressing
operation the addressing cable is removed again and the
module connected to the bus line. No 4 or 5-pole connecting
cable may be used for the addressing.
All standard K20 modules (not ASIsafe versions) support the
extended address mode and can be addressed with an A or B
address. Up to 62 slaves can thus be operated on one
AS-Interface network. The version with four inputs and four out-
puts (3RK2 400-1CT30-0AA3) works according to the new
AS-Interface Specification 3.0. Through Specification 3.0 it is
possible for even A/B slaves to have four outputs (instead of only
three possible up to now with Specification 2.1). Please note that
this module can be used only with a new master according to
AS-Interface Specification 3.0 (e.g. the new DP/AS-i LINK
Advanced) and that the cycle times for the outputs can extend
to max. 20 ms.

For simple connection of the K20 modules to the AS-Interface
flat cable there is a new series of AS-Interface distribution
boards and M12 feeders:
AS-Interface distribution boards
Like the AS-Interface 3RK1 901-1NN00 standard distribution
board, the new AS-Interface 3RK1 901-1NN10 compact
distribution board enables distribution of the AS-Interface flat
cable to several lines. The compact distribution board can be
used for a current carrying capacity of up to 6 A. It is character-
ized by particularly simple handling:
• insert the cable,
• swing closed and
• screw down with only one captive screw.
No additional seals are required for the compact distribution
board. The AS-Interface flat cable must always be passed
through the compact distribution board, i.e. it must never be
terminated inside the compact distribution board. For higher
currents and for cases where one of the two flat cables is to be
terminated inside the distribution board, the standard distribu-
tion board must be used.
AS-Interface M12 feeders
AS-Interface M12 feeders are available in the same design as
the compact distribution boards. They are required for transfer-
ring from the AS-Interface flat cable to a round cable. The
spectrum covers AS-Interface M12 feeders with different cable
lengths (1 and 2 m) and differentiates between M12 feeders for
AS-i/Uaux for connection of I/O modules and AS-Interface
without Uaux for connection of modules with inputs. These
AS-Interface M12 feeders are just as easy to handle as the
AS-Interface compact distributor. The flat cable must
always be passed through the M12 distribution board, i.e. it must
never be terminated inside the M12 distribution board. For the
event that the AS-Interface flat cable is to be terminated in the
M12 feeder, the standard M12 feeder (3RX9 801-0AA00) or the
quadruple M12 (feeder 3RK1 901-1NR00) are available.
The different possibilities of connecting the K20 modules to the
AS-Interface bus line and the 24 V DC auxiliary voltage are
presented in the following table:
To connect the feeder and the K20 module over a cable length
> 2 m it is also possible to use freely configurable cables with an
M12 cable box and an open cable end, which are fitted with an
M12 plug (straight version: 3RX8 000-0CD45, 3RX8 000-0CE45
angle plug ) and connected to the feeder.
This cable is available in two versions:
• 3RX8 000-0CB42-1AF0: 5 m long, with M12 cable box
• 3RX8 000-0CC42-1AF0: 5 m long, with M12 angle cable box
To connect more than one K20 modules to one spur line, the spur
line can be split again using a T distributor (3RK1 901-1TR00).

Options for connection of the K20 modules to other AS-Interface modules
Please note the following boundary conditions:
• The configuration guidelines for AS-Interface generally apply.
For all M12 connecting cables the maximum permissible
current is limited to 4 A. The cross-section of these cables
amounts to just 0.34 mm². For connection of the K20 modules
the previously mentioned M12 connecting cables can be used
for the spur lines. The voltage drop caused by the ohmic re-
sistance (approx. 0.11 Ω/m) must be taken into account.
• For round cable connections with joint routing of AS-i and Uaux
in one line the following maximum lengths apply:
- Yes, spur line from feeder to module: maximum 5 m
- Sum of all round cable pieces in one AS-Interface network:
maximum 20 m

■Function
Data transfer according to Analog Profile 7.3/7.4
With Analog Profile 7.3/7.4 at least seven AS-Interface cycles
must be passed through before transmission is completed. This
requires the use of a master according to Extended
Specification V2.1.
With input modules the complete analog value is then available
in the AS-Interface master. Preprocessing is thus performed in
the master.
With the next system function call the user program brings the
analog value as one value into the user program. Hence the
analog value is very quickly updated.
The analog value transmission allies in reverse order for the
output modules as well.
In total this results in the following maximum times before the
analog value with Profile 7.3/7.4 (with presetting: smoothing
function deactivated; line filter 50 Hz) is available:
Data transfer according to Analog Profile 7.A.9
With Analog Profile 7.A.9 only three or four AS-Interface cycles
are required for the transmission. This requires the use of a
master according to Extended Specification 3.0.
The maximum times before the analog value with Profile 7.A.9 is
available are presented in detail in the manual according to the
mode selected (resolution, number of channels,
A/B technology).

■Overview
SIRIUS solid-state switching devices
• Solid-state relays
• Solid-state contactors
• Function modules
SIRIUS – for almost unending activity
Conventional electromechanical switching devices are often
overtaxed by the rise in the number of switching operations. A
high switching frequency results in frequent failure and short re-
placement
cycles. However, this does not have to be the case, because
with the latest generation of our SIRIUS solid-state switching de-
vices we provide you with solid-state relays and contactors with
a particularly long service life – for almost unending activity even
under the toughest conditions and under high mechanical load,
but also in noise-sensitive areas.
Proved time and again in service
SIRIUS solid-state switching devices have become firmly estab-
lished in industrial use. They are used above all in applications
where loads are switched frequently – mainly with resistive load
controllers, with the control of electrical heat or the control of
valves and motors in conveyor systems. In addition to its use in
areas with high switching frequencies, thanks to its silent
switching SIRIUS is also ideally suited to noise-sensitive areas
such as offices or hospitals.
The most reliable solution for any application
Compared with mechanical switching devices, our SIRIUS solid-
state switching devices stand out because of their considerably
longer service life. Thanks to the high product quality, their
switching is extremely precise, reliable and above all insuscep-
tible to faults. With its variable connection methods and a wide
spread of control voltages, the SIRIUS family is universally appli-
cable. Depending on the individual requirements of the applica-
tion, our modular switching devices can also be quite easily
expanded by the addition of standardized function modules.
Always on the sunny side with SIRIUS
Because SIRIUS offers even more:
• The space-saving and compact side-by-side mounting
ensures reliable operation up to an ambient temperature of
+60 °C.
• Thanks to fast configuration and the ease of installation and
start-up, you save not only time but also expenses.

■Application
Solid-state relays
SIRIUS solid-state relays are suitable for surface mounting on
existing cooling surfaces. Installation is quick and easy,
involving just two screws. The special technology of the power
semiconductor ensures there is excellent thermal contact with
the heat sink. Depending on the nature of the heat sink, the
capacity reaches up to 88 A on resistive loads.
The solid-state relays are available in three different versions:
• 3RF21 single-phase solid-state relay with a width of 22.5 mm
• 3RF20 single-phase solid-state relay with a width of 45 mm
• 3RF22 three-phase solid-state relay with a width of 45 mm
The 3RF21 and 3RF22 solid-state relays can be expanded with
various function modules to adapt them to individual applica-
tions.
Solid-state contactors
The complete units consist of a solid-state relay plus optimized
heat sink, and are therefore ready to use. They offer defined
rated currents to make selection as easy as possible. Depend-
ing on the version, current intensities of up to 88 A are achieved.
Like all of our solid-state switching devices, one of their parti-
cular advantages is their compact and space-saving design.
With their insulated mounting foot they can easily be snapped
onto a standard mounting rail, or they can be mounted on carrier
plates with fixing screws. This insulation enables them to be
used in circuits with protective extra-low voltage (PELV) or safety
extra-low voltage (SELV) in building engineering. For other appli-
cations, such as for extended personal safety, the heat sink can
be grounded through a screw terminal.
The solid-state contactors are available in two different versions:
• 3RF23 single-phase solid-state contactors
• 3RF24 single-phase solid-state contactors
The 3RF20 and 3RF21 single-phase solid-state relays and the
3RF23 single-phase solid-state contactors are described in
Catalog LV 1 · 2006.
■Design
3RF22 three-phase solid-state relay with a width of 45 mm
With its compact design, which stays the same even at currents
of up to 55 A, the 3RF22 solid-state relay is the ultimate in space-
saving construction, at a width of 45 mm. Installation on cooling
surfaces is quick and easy, involving just two screws. The logical
connection arrangement, with the power infeed from above and
connection of the load from below, ensures tidy installation in the
control cabinet.
3RF24 three-phase solid-state contactors
The compact design enables small compact units with currents
up to 50 A. All special features of the solid-state relays for saving
time and space are effective here too.
■Function
Two-phase controlled version
In many three-phase applications there is no need of a three-
phase controller. Loads in a delta circuit or wye circuit, which
have no connection to the neutral conductor, can be safely
switched on and off using only two phases.
Nevertheless, the 3RF22 and 3RF24 three-phase solid-state
switching devices provide the possibility of connecting all three
phases to the switching device, with the middle phase looped
directly through the device. Thanks to the lower power loss
compared to a three-phase controlled device it is possible for
the mounted accessories to be more compact.
Three-phase controlled version
This version is used in three-phase applications which have to
switch all phases on and off for system reasons or in the case of
loads in a wye circuit with connection to the neutral conductor.
Version for resistive loads, "zero-point switching"

Selecting solid-state relays
When selecting solid-state relays, in addition to information
about the power system, the load and the ambient conditions it
is also necessary to know details of the planned design. The
solid-state relays can only conform to their specific technical
specifications if they are mounted with appropriate care on an
adequately dimensioned heat sink. The following procedure is
recommended:
• Determine the rated current of the load and the mains voltage
• Select the relay design and choose a solid-state relay with
higher rated current than the load
• Determine the thermal resistance of the proposed heat sink
• Check the correct relay size with the aid of the diagrams.
1) The type current provides information about the performance of the
solid-state relay.
The actual permitted rated operational current Ie can be smaller
depending on the connection method and cooling conditions.
2) Please note that the version with an M4 screw terminal can only be used
for a rated current of up to approx. 50 A and a conductor cross-section of
10 mm2
.
3) Please note that this version can only be used for a rated current of up to
approx. 20 A and a conductor cross-section of 2.5 mm2.

Selecting solid-state contactors
The solid-state contactors are selected on the basis of details of
the power system, the load and the ambient conditions. As the
solid-state contactors are already equipped with an optimally
matched heat sink, the selection process is considerably
simpler than that for solid-state relays.
The following procedure is recommended:
• Determine the rated current of the load and the mains voltage
• Select a solid-state contactor with the same or higher rated
current than the load
• Check the correct contactor size with the aid of the rated
current diagram, taking account of the design conditions

■Overview
Function modules for SIRIUS solid-state switching devices
A great variety of applications demand an expanded range of
functionality. With our function modules, these requirements can
be met really easily. The modules are mounted simply by
clicking them into place; straight away the necessary connec-
tions are made with the solid-state relay or contactor. The plug-in
connection to control the solid-state switching devices can
simply remain in use.
All three-phase solid-state switching devices in the version with
a control supply voltage of 4 to 30 V DC can be supplemented
with the 3RF29 00-0EA18 converter.
Details of the converter can be found in the Catalog LV1 · 2006.
Power control regulators for single-phase solid-state
devices
The following functions have been integrated:
• Power control regulator for adjusting the power of the con-
nected load. Here, the setpoint is set with a rotary knob on the
module as a percentage with reference to the 100 % power
stored as a setpoint.
• Inrush current limitation: With the aid of an adjustable
voltage ramp, the inrush current is limited by means of phase
control. This is useful above all with loads such as lamps or
infrared lamps which have an inrush transient current.
• Load circuit monitoring for detecting load failure, partial load
faults, alloyed power semiconductors, lack of voltage or a
break in the load circuit.
■Application
The power control regulator adjusts the current in the connected
load by means of a solid-state switching device depending on a
setpoint. The setpoint can be predefined externally as a 0 to
10 V signal or internally by means of a potentiometer. Depending
on the setting of the potentiometer (tR), the control is carried out
according to the principle of full-wave control or generalized
phase control.
Full-wave control
In this operating mode the output is adjusted to the required
setpoint by changing the on-to-off period. The period duration is
predefined at one second.
Generalized phase control
In this operating mode the output is adjusted to the required
setpoint by changing the current flow angle. In order to observe
the limit values of the conducted interference voltage for indus-
trial networks, a choke rated at at least 200 µH must be included
in the load circuit.
Special versions 3RF29 04
The 3RF29 04 versions are not equipped with the partial load
monitoring function. The 3RF29 04-0KC0 version is pro-
grammed in addition for no current to flow in the solid-state
switching device during the teach routine.

■Design
There is no typical design of a load feeder with solid-state relays
or solid-state contactors; instead, the great variety of connection
systems and control voltages offers universal application oppor-
tunities. SIRIUS solid-state relays and solid-state contactors can
be installed in fuseless or fused feeders, as required. There are
special versions with which it is even possible to achieve
short-circuit strength in a fuseless design.
■Function
Connection technique
All SIRIUS solid-state switching devices are characterized by
the great variety of connection methods. You can choose be-
tween the following connection techniques:
Screw terminal system
The screw connection system is the standard among industrial
controls. Open terminals and a plus-minus screw are just two
features of this technology. Two conductors of up to 6 mm² can
be connected in just one terminal. As a result, loads of up to 50 A
can be connected.
Spring-loaded connection system
This innovative technology manages without any screw connec-
tion. This means that very high vibration resistance is achieved.
Two conductors of up to 2.5 mm² can be connected to each
terminal. As a result, loads of up to 20 A can be dealt with.
Ring terminal end connection
The ring terminal end connection is equipped with an M5 screw.
Ring terminal ends of up to 25 mm² can be connected. In this
way it is possible to connect even high powers with current
intensities of up to 90 A safely. Finger-safety is provided in this
case too with a special cover.
Switching functions
In order to guarantee an optimized control method for different
loads, the functionality of our solid-state switching devices can
be adapted accordingly.
The "zero-point switching" method has proved to be ideal for
resistive loads, i.e. where the power semiconductor is activated
at zero voltage.
For inductive loads, on the other hand, for example in the case
of valves, it is better to go with "instantaneous switching". By
distributing the ON point over the entire sine curve of the mains
voltage, disturbances are reduced to a minimum.
Performance characteristics
The performance of the solid-state switching devices is substan-
tially determined by the type of power semiconductors used and
the internal design. In the case of the SIRIUS solid-state contac-
tors and solid-state relays, only thyristors are used in place of
less powerful Triacs.
Two of the most important features of thyristors are the blocking
voltage and the maximum load integral:
Blocking voltage
Thyristors with a high blocking voltage can also be operated
without difficulty in power systems with high interference
voltages. Separate protective measures, such as a protective
circuit with a varistor, are not necessary in most cases.
With SIRIUS solid-state switching devices, for example, thyris-
tors with 800 V blocking voltage are fitted for operation in power
systems up to 230 V. Thyristors with up to 1600 V are used for
power systems with higher voltages.
Maximum load integral
One of the purposes of specifying the maximum load integral
(I²t) is to determine the rating of the short-circuit protection. Only
a large power semiconductor with a correspondingly high I²t
value can be given appropriate protection against destruction
from a short-circuit by means of a protective device matched to
the application. However, SIRIUS solid-state switching devices
are also characterized by the optimum matching of the thyristors
(I²t value) with the rated currents. The rated currents specified on
the devices according to EN 60947-4-3 were confirmed by
extensive testing.

■Integration
Notes on integration in the load feeders
The SIRIUS solid-state switching devices are very easy to inte-
grate into the load feeders thanks to their industrial connection
technology and design.
Particular attention must however be paid to the circumstances
of the installation and ambient conditions, as the performance of
the solid-state switching devices is largely dependent on these.
Depending on the version, certain restrictions must be
observed. Detailed information, for example in relation to solid-
state contactors about the minimum spacing and to solid-state
relays about the choice of heat sink, is given in the product data
sheets and the technical specifications in the A&D Mall.
Despite the rugged power semiconductors that are used,
solid-state switching devices respond more sensitively to
short-circuits in the load feeder. Consequently, special precau-
tions have to be taken against destruction, depending on the
type of design.
Siemens generally recommends using SITOR solid-state protec-
tion fuses. These fuses also provide protection against destruc-
tion in the event of a short-circuit even when the solid-state
contactors and solid-state relays are fully utilized.
Alternatively, if there is lower loading, protection can also be
provided by standard fuses or miniature circuit-breakers. This
protection is achieved by overdimensioning the solid-state
switching devices accordingly. The technical specifications in
the A&D Mall and the product data sheets contain details both
about the solid-state fuse protection itself and about use of the
SIRIUS devices with conventional protection equipment.
The SIRIUS solid-state switching devices are suitable for inter-
ference-free operation in industrial power systems without
further measures. If they are used in public power systems, it
may be necessary for conducted interference to be reduced by
means of filters. This does not include the special solid-state
contactors of type 3RF23..-.CA.. "Low Noise". These comply with
the class B limit values up to a rated current of 16 A. If other
versions are used, and at currents of over 16 A, standard filters
can be used in order to comply with the limit values. The decisive
factors when it comes to selecting the filters are essentially the
current loading and the other parameters (operational voltage,
design type, etc.) in the load feeder.
Suitable filters can be ordered from EPCOS AG.

Arrangement example
Given conditions: Ie = 55 A and Ta = 40 C.
The task is to find the thermal resistance Rthha and the heat sink
overtemperature dTha.
From the diagram on the left → PM = 227 W,
from the diagram on the right → Rthha = 0.09 K/W.
This results in:
dTha = Rthha × PM = 0.09 K/W × 227 W = 20.4 K.
At dTha = 20.4 K the heat sink must therefore have an
Rthha = 0.09 K/W.

■Overview
The complete units consist of a solid-state relay plus optimized
heat sink, and are therefore ready to use. They offer defined
rated currents to make selection as easy as possible. Depend-
ing on the version, current intensities of up to 50 A are achieved.
Like all of our solid-state switching devices, one of their particu-
lar advantages is their compact and space-saving design. With
their insulated mounting foot they can easily be snapped onto a
standard mounting rail, or they can be mounted on carrier plates
with fixing screws. This insulation enables them to be used in
circuits with protective extra-low voltage (PELV) or safety
extra-low voltage (SELV) in building engineering. For other appli-
cations, such as for extended personal safety, the heat sink can
be grounded through a screw terminal.
Version for resistive loads, "zero-point switching"
This standard version is often used for switching space heaters
on and off.
1) These products were built as Class A devices. The use of these devices in
residential areas could result in radio interference. In this case the may be
required to introduce additional damping measures.
