ELECTRICAL & ELECTRONICS COMMUNICATION
What is PLC and its working principle?
Principle of Programmable Logic Controller: Programmable Logic Controllers are utilized for constantly checking the information esteems from sensors and produces the yields for the activity of actuators dependent on the program. Each PLC framework involves these three modules: CPU module. Force gracefully module

What are the three types of PLC?
Principle of Programmable Logic Controller: PLC are partitioned into three kinds dependent on yield in particular Relay yield, Transistor yield, and Triac Output PLC. The hand-off yield type is most appropriate for both AC and DC yield gadgets. Transistor yield type PLC utilises exchanging activities and utilised inside chip.
