Omron CPM1A-40CDR-A-V1 Programmable Controller

The Omron CPM1A-40CDR-A-V1 is a DIN-rail mounted PLC CPU module in the CPM1A series that delivers 40 I/O points—24 inputs and 16 relay outputs—from a 230 VAC power supply. It reads 24 VDC input signals, runs a control program with a capacity of about 2K steps, and stores data in built-in memory. A peripheral RS-232C port (via adapter) supports basic communications, and the unit can be expanded with additional expansion units to scale I/O as needed. Designed for rugged industrial use, it mounts on a DIN rail and operates from 0°C to +55°C, with LED status indicators for quick health checks. This CPM1A-40CDR-A-V1 PLC is commonly used for machine automation, sequencing, and process control tasks in packaging machines, conveyor systems, assembly lines, and OEM equipment requiring reliable PLC-based control. It finds application across manufacturing lines, material handling systems, and food processing equipment where dependable control is required for small to mid-scale automation. For compatibility, common replacements include Omron CP1E-N40DR-A, CPM2A-40CDR-A, and CP1L-M40DR-A, making it a versatile option in mid-range automation projects.
