PLC Panels

Description

A PLC (Programmable Logic Controller) Panel is an industrial control panel that houses a PLC and related components to automate, monitor, and control machines and industrial processes. It receives signals from sensors, processes them according to the programmed logic, and sends output signals to actuators such as motors, valves, and relays.
