The Omron CPM1A-30CDR-D-V1 is a compact 30-point input/output CPU unit designed for small-scale automation systems. It operates on a DC power supply and features relay output type, providing robust switching capabilities for industrial loads. The unit includes 18 input points and 12 output points, supporting flexible I/O configuration. Expansion is possible through connection with additional I/O units, allowing the system to scale from 10 to up to 100 I/O points when combined with expansion modules.

The CPM1A series supports connection to programmable terminals (PTs) via communication adapters, enabling high-speed data exchange through protocols such as Host Link or High-Speed NT Link. This ensures efficient human-machine interface (HMI) integration. The series offers a range of CPU units from 10 to 40 points, available in both AC and DC power supply versions to suit different application environments.

The CPM1A incorporates advanced functions including high-speed response, high-speed counting, and interrupt processing, making it suitable for precise control tasks. Additionally, it features two analog potentiometers for on-the-fly adjustment of settings, enhancing operational flexibility. These capabilities make the CPM1A a versatile and reliable choice for small to medium-scale automation applications.
