Programmable logic controller
A programmable logic controller (PLC) is a digital system used to make electrical and mechanical processes become automated. PLC can be found in almost all of the heavy industries which require process and sequences. PLC contains a unique set of inputs and outputs. The logic of PLC is programmed so that user can create a highly dedicated PLC working system for their intended purpose.
