What is a PLC System?
A Programmable Logic Controller (PLC) is an industrial computer designed to control machinery and automation processes.
PLCs receive inputs from sensors and execute programmed instructions to control outputs such as:
- motors
- valves
- relays
- actuators
Unlike traditional computers, PLCs are built to operate in harsh environments and deliver real-time performance with high reliability.
What Are Industrial Control Boards?
Industrial control boards are electronic circuits used to manage and regulate industrial equipment.
They include:
- relay boards
- logic boards
- interface boards
- controller modules
These boards act as intermediaries between sensors, PLCs, and machinery.
Types of Industrial Control Components
PLC Modules
PLC systems consist of modular components that perform different functions.
Example:
