SENSOR

Programmable logic controller

The most basic function of a Programmable logic controller (PLC) is to receive

 inputs from status components, which can be from sensors or switches. Some of the basic components of a PLC are input modules, a central processing unit, output modules, and a programming device.

What are the basic components of a PLC?

Without any of these major components, the PLC will fail to function properly. Thebasic components include a power supply, central processing unit (CPU or processor), co-processor modules, input and output modules (I/O), and a peripheral device.

What are the parts of PLC?

Programmable Logic Controllers have three components. These three PLC components are: processor, power supply, and an input/output (I/O) section. The processor, or the brain of the PLC system, is a solid-state device designed to perform a wide variety of production, machine tool, and process-control functions
