Featured this month: IFS-10, SIL3/PLe functional safety. IFS-10 safety controller family from Lika Electronic is designed for safe monitoring of speed, standstill and direction of motion of incremental encoders and sensors both “safe” and “non safe” to be integrated into systems that require up to SIL3/PLe Functional Safety Level. Also for SSI absolute encoders available soon.

IFS-10, SIL3/PLe functional safety
IFS-10 safety controller family from Lika Electronic is designed for safe monitoring of speed,
standstill and direction of motion of incremental encoders and sensors both “safe” and “non safe”
to be integrated into systems that require up to SIL3/PLe Functional Safety Level.
Also for SSI absolute encoders available soon.
IFS-10 SIL3 / PLe certified modules are designed for safe monitoring of underspeed, overspeed, standstill and direction of
motion of incremental encoders and sensors both “safe” and “non safe” to be integrated into systems that require up to SIL3
Safety Integrity Level and up to PLe Performance Level. IFS-10 controllers allow to create a redundant safety subsystem by
connecting at input 1Vpp sine-cosine or TTL/RS-422 or HTL/Push-Pull encoders, but also proximity sensors, limit switches and
HTL/PNP command devices (a further version designed to connect at input SSI absolute encoders will be available soon).
So they monitor underspeed, overspeed, standstill and direction of motion by means of STO, SS1, SS2, SOS, SLS, SDI, SSM
safety functions in compliance with the EN61800-5-2 standard in order to achieve the required safety level.
The monitors can be equipped with 1 4-20mA analog output, 1 5-36Vdc relays output and up to 4 HTL control outputs, all safe.
In specific models they are further fitted with additional sine-cosine or RS-422 splitter outputs that provide additional safe
encoder signals to subsequent controller. The set-up of all functions and the parametrization of input and output features are
performed by using either the PC software tool supplied for free or the optional and removable OLED display and programming
module IFS-10-PM.
The robust and compact enclosure is further fitted with two LEDs for status monitoring and the clip for DIN rail mounting.
By virtue of their great versatility and the broad compatibility IFS-10 safety controllers are perfect both for installation in
modern certified automation systems and in case of retrofitting of outdated plants, such us in the automation of stage machi-
nery, swiveling platforms, packaging lines, conveying and storage systems, cranes, working machines, wind turbines, industrial
robots and manipulators.
Among the key features:
• IFS-10S / IFS-10SA: 1 input for safe SIL3/PLe certified sine/cosine encoders
• IFS-10 / IFS-10A: 2 inputs for sine-cosine, TTL and HTL encoders, freely combinable
• Also for SSI absolute encoders available soon
• SIL3 and PLe Certification
• STO, SS1, SS2, SOS, SLS, SDI, SSM safety functions in compliance with EN61800-5-2
• Input frequency up to 500 kHz
• 1 force guided (NO) redundant relay output
• 4 control outputs, Push-Pull, short-circuit protected, each one inverted and redundant
• 1 safe and scalable 4-20mA 14-bit analog output
• +18Vdc +30Vdc operating voltage
• Compact case with DIN rail mounting
• Configuration via USB port and software tool or via optional display and programming module (IFS-10-PM)
• IFS-10S / IFS-10SA: 1 input for safe SIL3/PLe certified sin/cos encoders
• IFS-10 / IFS-10A: 2 inputs for sine-cosine,
TTL and HTL encoders, freely combinable
• Also for SSI absolute encoders available soon
• SIL3 and PLe Certification
• STO, SS1, SS2, SOS, SLS, SDI, SSM safety functions
in compliance with EN61800-5-2
