Components of PLC
The components of a Programmable Logic Controller (PLC) consist of three primary elements: input modules, CPU, and output modules. Input modules facilitate the connection of sensors and switches to the PLC, converting physical signals into digital data that the CPU can process. The CPU, often referred to as the brain of the PLC, executes programmed instructions and coordinates the operation of the input and output modules to control industrial processes effectively. Output modules interface with actuators and other devices, converting digital signals from the CPU into physical actions, thus completing the feedback loop of the automation system.
