What is a PLC?

A Programmable Logic Controller (PLC) is an industrial computer designed to control machinery and processes in manufacturing environments. Key features of a PLC include:

• Inputs: Signals received from sensors, switches, or other devices.
• Outputs: Commands sent to actuators, motors, or lights.
• Programming: Logic created using software to dictate how the system responds to inputs.
