PLC CPU

A PLC CPU is the processor module that holds the program and runs the scan, reading the input image, solving the logic and writing outputs on every cycle. Controls engineers pick one when a controller has to be specified by memory and scan speed rather than I/O count, when a failed processor has stopped a line, or when an expansion needs more racks than the existing CPU can address.

 

As an authorized electrical distributor for multiple manufacturers, we stock PLC processors and control modules from Finder, Carlo Gavazzi and more across competing lines, in a range of expansion rack counts and release times, so you can match the rack count and timing the system requires, compare expansion capacity and response across brands, and keep a platform a plant already programs in.
