Control Systems & Programmable Logic Controllers
A PLC is a programmable logic controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. PLCs were designed to replace automated systems that used timers, relays and sequencers. A programmable logic controller can replace thousands of relays. PLC'c were originally used in the auto industry, where software replaced hard-wired control panels.
The original PLC application, then called a modular digital controller, was used by General Motors. It had been developed to help GM eliminate old style relay based machine control systems. PLC's have replaced old style mechanical controllers in many industries including machining, packaging, material handling and automated assembly. They provide more precise, reliable and durable solutions in controlling industrial processes.
We have an unsurpassed selection of new and used PLCs for a variety of applications.
