The Omron CP1W-DA021 PLC Analog Output Expansion Unit provides 2 analog outputs for generating voltage and current control signals within compatible Programmable Logic Controller systems. It supports output ranges including 1 to 5 V, ±10 V, and 4 to 20 mA, allowing PLC control values to be converted into analog electrical signals for compatible process equipment. The module consumes 40 mA at 5 V and 95 mA at 24 V while expanding the controller with two analog output channels. This configuration supports machine and process applications requiring variable analog control signals. The CP1W-DA021 extends the CP1W architecture and forms part of the PLC analog output range available for Omron process automation.
