Chapter 13, Problem 25RQ
Program Plan Intro
Programmable Logic Controller (PLC):
- Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
- PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
- The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling
programming language.
Solenoid:
- The working of solenoid is based on the principle of magnetic induction.
- It contains a coil, frame, and a plunger known as armature.
- The main function of solenoid is to convert electrical signals into
mechanical motion. - Due to its magnetic movement, solenoid is used in different areas such as locking of two devices, interlocking of gear wheel in automobiles, and some other medical application.
