This document discusses various electronic equipment used in industries. It describes data loggers that record data from sensors connected to a microcontroller. Temperature sensors that convert heat into electrical signals for devices like induction furnaces are explained. Thyristors are described as switching devices with four layers that control current flow. Programmable logic controllers (PLCs) are discussed as industrial computers that automate processes through input and output modules connected to a central processing unit. Pressure sensors and EEPROM memory are also summarized. The document provides information on key electronic devices commonly found in industrial applications.

4. ELECTRONIC EQUIPMENTS
 Electrical equipment includes any machine
powered by electricity. It usually consists of
an enclosure, a variety of electrical components,
and often a power switch.
Examples of these include:
 Major appliance
 Microcontroller
 PLC
 Small appliances

5. DATA LOGGER
• THESE ARE THE DEVICES USED TO RECORD
DATA OF DIFFERENT QUANTITIES.THEY
HAVE SENSOR CONNECTED TO
MICROCONTROLLER FURTHER CONNECTED
TO TACT SWITCHES AND SERIAL
INETERFACE.
• THE TACT SWITCHES MAKE DATA LOGGER
TO START/STOP AND SEND/RESET DATA IN
DATA LOGGER . ANOTHER FUNCTION THEY
DO ARE SETTING UP TIME.
• TO READ DATA WE CONNECT IT TO A
COMPUTER USING SERIAL INTERFACE AND
WITH HELP OF SOFTWARE WE READ THEM.

6. TEMPERATURE SENSOR

7. IT HAS THERMOCOUPLE WICH CONVERT THE HEAT
GENERATED INTO ELECTRICAL SIGNAL AND IT IS
TRANSMITTED TO THE MICROCONTROLLER FROM WHERE
THE DATA IS TRANSMITTED TO OTHER CIRCUITS.
APPLICATION:
•• INDUCTION FURNACE IS USED TO MELT
RODS ETC AND IT IS VERY ECO FRIENDLY
METHOD.
•• TEMPERATURE SENSORS ARE
ACCURATE AND NOW THEY ARE PART OF
DEVICES LIKE INDUCTION FURNACE.

8. THYRISTOR
• THYRISTOR IS A DEVICE OF FOUR LAYERS OF ALTERNATING
P AND N TYPE MATERIAL DUE TO WHICH IT CONSIST OF 3
JUNCTION AND THREE TERMINAL ANODE (A), CATHODE (K)
AND GATE(G).
• IF WE APPLY SOME VOLTAGE AT GATE THEN THE
DEPLETION LAYER AT J2 WILL DECREASE AND AVALACHE
BREAKDOWN IS ACHIEVED QUICKLY. THAT’S WHY GATE IS
ALSO CALLED CONTROL TERMINAL.

9. APPLICATION
• THE THYRISTORS ARE USED
IN THE DEVICES FROM
CALCULATOR TO COMPUTER.
THE THYRISTOR ACT AS
SWITCH.
• IT IS CAPABLE OF HANDLING
HIGH POWERS. SO, THEY ARE
USED AS SUPPLY
CONTROLLERS ALSO.
• THEY ARE ALSO USED AS
THE RECTIFIERS.

10. P . L . C
• Plc is an industrial computer
that monitors inputs, makes
decisions based on its program
and controls outputs to
automate a process or machine.
• The automation of many
different processes, such as
controlling machines or factory
assembly lines, is done through
the use of small computers
called a programmable logic
controllers.

11. WHY PLC?
• To reduce Human efforts.
• To get maximum efficiency from
machine and control them with human logic.
• To reduce complex circuitry of entire
system.
• To eliminate the high costs associated
with inflexible , relay-controlled systems.

12. COMPONETS OF PLC(INPUT/OUTPUT)
– 1.INPUT MODULES accepts and converts signals from sensors into a
logic signal.
– Ex: switches , pushbuttons.
– 2.OUTPUT MODULES that convert control instructions a signal that
can be used by actuators.
– Ex: lamps, alarm.
– 3.MEMORY is the component that stores information , programs and
data in a PLC.
– Types of memory used in PLCs are read only memory (ROM) and
random access memory (RAM).

13. 4.CENTAL PROCESSING UNIT(CPU) is the
brain of PLC and governs the activities of the
entire PLC systems.
The CPU consists of following Blocks:
Arithmetic Logic Unit(ALU),
Internal memory of CPU
Internal tmers , counters and flags.
5.POWER SUPPLY
Provides the voltage needed to run the
primary PLC
Components.

14. 6.
PROGRAMMING
DEVICE
It is the
programming
terminal is
used for
programming
the PLCs and
monitoring/
sequencing
PLCs operation.

15. PRESSURE SENSOR
A pressure sensor is a device for pressure measurement of gases or
liquids. Pressure is an expression of the force required to stop a fluid from
expanding, and is usually stated in terms of force per unit area. A pressure
sensor usually acts as a transducer; it generates a signal as a function of
the pressure imposed. For the purposes of this article, such a signal is
electrical.

16. EEPROM
EEPROM stands
for electrically erasable programmable r
ead-only memory and is a type of non-
volatile memory used in computers and
other electronic devices to store
relatively small amounts of data but
allowing individual bytes to be erased
and reprogrammed.
It also has a limited life for erasing and
reprogramming, now reaching a million
operations in modern EEPROMs. In an
EEPROM that is frequently
reprogrammed while the computer is in
use.
