Omron CQM1-CPU45-EV1 Programmable Logic Controller Module

The Omron CQM1-CPU45-EV1 is a CPU module that serves as the central processing unit for Omron’s CQM1 Programmable Logic Controller family, enabling the execution of ladder logic and other PLC program control within compact automation setups. As the controller’s core, it coordinates logic operations, timers, and counters while interfacing with expansion I/O and field devices through the CQM1 system backplane, making it suitable for small to mid‑size automation tasks. This part number—CQM1-CPU45-EV1—identifies the CPU module used in Omron’s modular PLC architecture, allowing users to build and maintain modular control systems with straightforward upgrade paths and reliable determinism for applications such as machine sequencing, packaging lines, conveyors, and general automation control.
