This MITSUBISHI ELECTRIC QCPU listing covers CPU modules for the MELSEC-Q Series PLC platform. The CPU executes the user program, processes I/O data and manages network and intelligent modules mounted on the base. Models differ in program capacity, processing speed and built-in ports, and are used in factory automation systems of many sizes.
