Specification

The MITSUBISHI Q02UCPU is a versatile and powerful CPU module from the Q Series family, designed to deliver robust performance in demanding industrial automation environments. It operates on a stored program cyclic control method with refresh I/O control, ensuring consistent and predictable execution. With program capacity up to 20K steps and support for 8192 I/O device points, the Q02UCPU is ideal for applications requiring high-speed processing and extensive I/O configurations. Its constant scan feature allows precise timing adjustments from 0.5 ms to 2000 ms, while the extended SRAM cassette port (40 ns) provides additional memory flexibility for complex programs.
