What is a PLC in Automation?

A Programmable Logic Controller (PLC) is a specialised computer used to control machines and industrial processes. It is designed to withstand the demanding conditions of industrial environments while offering real-time control over manufacturing operations.

A PLC operates by receiving input signals from various sensors, processing these inputs according to a pre-programmed logic, and then controlling outputs that drive machinery or processes.

PLCs play an essential role for our clients in automating complex systems, making them indispensable across a wide range of industries, including manufacturing, automotive, food and beverage, pharmaceuticals, and more.

By minimising human intervention, PLCs enhance efficiency, improve safety, and ensure consistency in operations.
