  • What is a Programmable Logic Controller (PLC) (with picture)

    In many cases a programmable logic controller allows all of the relays and timers within a factory system to be replaced by a single controller. Modern PLCs deliver a wide range of functionality including basic relay control motion control process control and complex networking. They also can be used in a distributed control system (DCS).
