Introduction:
In PLC (Programmable Logic Controller) is an electronic solid-state device that can control a process or a machine and has the ability to be programmed or reprogrammed quickly according to the demand of the application.
It was invented to replace the relay-based sequential circuits that were necessary for machine control. The PLC works by monitoring its inputs, and depending on its status, activating and deactivating its outputs.

PLCs are used in many applications:
- Parts machining
- Packaging machines
- Material handling
- Automatic assembly
- Petrochemical / Chemical
- Mining
- And in general, any type of application that requires electrical controls can use a PLC.
