The Omron CP1W-DA042 PLC Analog Output Expansion Unit provides 4 channels for generating voltage and current signals from compatible Programmable Logic Controller systems. It supports output ranges including 0 to 10 V, ±10 V, and 4 to 20 mA with 1/12000 resolution, allowing PLC control values to be converted into analog electrical signals for compatible process equipment. The module consumes 70 mA at 5 V and 160 mA at 24 V while adding four analog output channels to the CP1W control architecture. This configuration supports applications requiring multiple variable control signals from one expansion unit. The CP1W-DA042 expands CP1W analog capability and forms part of the high-resolution PLC analog output range within Omron process automation.
