The Omron CQM1-DA022 is a high-performance analog output module designed specifically for the CQM1/CQM1H series programmable logic controllers (PLCs). As a reliable digital-to-analog (D/A) converter, it accurately converts the PLC's digital control commands into standard analog voltage or current signals, and is widely used in industrial automation control systems.
This module integrates a DC/DC converter as its built-in power supply, eliminating the need for an external power supply unit like some other models, effectively simplifying system installation and wiring.
