Omron CQM1-CPU41-V1 Programmable Logic Controller

The Omron CQM1-CPU41-V1 is a compact programmable logic controller (PLC) CPU unit with an integrated power supply, designed for small- to mid-sized industrial machines requiring reliable logic processing and coordinated control. It is commonly used in standalone machine panels, OEM automation setups, and distributed control applications such as packaging machines, conveyors, pump and compressor skids, material handling lines, and assembly processes. Key specifications include a program capacity of approximately 7.2 KB and about 4,096 words of data memory, with expandable I/O up to 256–384 points and a built-in 16 input points at the CPU base. It provides a built-in RS-232C port, accepts 100–230 VAC input, and achieves an execution speed of roughly 0.96 µs per instruction. Mounting options cover DIN rail or panel installation, and it belongs to the Omron CQM1 series as a modular PLC with expandable I/O units. For easier replacement planning, common alternatives include the Omron CQM1-CPU43-V1, CJ1M series PLCs, and CP1H series PLCs.
