What is PLC?

A Programmable Logic Controller (PLC) is a rugged digital computer used in industrial automation to control manufacturing processes, machinery, and assembly lines

Main Parts of a PLC

Central Processing Unit (CPU): The brain of the system that contains the microprocessor and memory, running the control logic.

• Input Modules: Circuits that receive real-world signals from sensors and switches, isolate voltage spikes, and convert them into data the CPU can read.

Output Modules: Components that translate the CPU's logical decisions into control signals for external devices like motors, valves, and lights.

Power Supply: Converts standard AC line voltage into low-voltage DC power required by the internal processor and modules
