Programmable Logic Controller (PLC)

A Programmable Logic Controller (PLC) is a digital computer used to control machines and processes in various industries. Think of it as a smart relay that automates tasks like controlling lights, motors, and conveyor belts. Programmers input specific instructions into the PLC, allowing it to respond to various inputs—like sensors—and trigger outputs accordingly. This flexibility enables efficient operation in manufacturing, traffic systems, and many other applications. PLCs are reliable, can withstand harsh environments, and can be easily reprogrammed to adapt to new tasks, making them essential tools in modern automation.
