Omron
Omron’s CPM1A-20CDR-D-V1 is a compact PLC CPU unit designed for small to mid-scale control tasks where reliable discrete I/O and 24 VDC power are required. The unit provides 20 total I/O points configured as 12 digital inputs at 24 VDC and 8 relay outputs rated up to 2 A at 250 VAC/24 VDC, making it suitable for driving contactors and signaling devices without external output modules. It supports panel or surface mounting and operates in ambient temperatures from 0 to +55 °C. The CPM1A architecture allows scalable systems with base I/O counts of 10, 20, 30, and 40, expandable up to 100 I/O via dedicated expansion modules including analog I/O, temperature sensor inputs, and serial communications. A peripheral communications port is built in for programming and integration. Typical applications include machine control, packaging lines, and general-purpose automation where a robust brick-style PLC is preferred.
