PLCs

Programmable logic controllers (PLCs) are solid-state, electronic devices that control the operation of a machine or process. PLCs are general-purpose controllers that can control and monitor any industrial machine or process.

They use logic functions, that are programmed into their memory via programming software. In simple terms, a PLC is the “brains” behind an automated process.  

PLCs are designed to monitor inputs from sources like pressure sensors, temperature sensors, limit switches, auxiliary contacts, and pilot devices.
