PLCs

A Programmable Logic Controller (PLC) is a specialized industrial computer designed to automate and control machines and manufacturing processes. It receives input signals from devices such as sensors and switches, processes these signals according to a user-defined program, and sends output signals to control actuators such as motors, valves, and relays. PLCs are widely used in industrial automation because they offer high reliability, strong resistance to electrical interference, flexible programming, easy maintenance, and excellent scalability, making them a key component of modern automated control systems.
