A PLC processor, also known as a Programmable Logic Controller Processor, are essential industrial automation components. They control and coordinate the various functions of equipment. A PLC processor receives input data from sensors, switches, and other devices, processes the data according to the programmed instructions, and sends output signals to actuators and other devices. They are used in a wide range of industrial applications, including manufacturing, transportation, and building automation, to improve efficiency, productivity, and safety. Selecting the right PLC Processor depends on factors such as the number of I/O points, processing speed, memory capacity, and communication protocols. At SIGMA Surplus we carry Allen Bradley PLC processors, Siemens PLC processors, Mitsubishi PLC processors, and several more by leading manufacturers.
