Omron CP1W-DA021 Analog Output Module

The Omron CP1W-DA021 Analog Output Module is a 2-channel D/A expansion unit for the Omron CP1W PLC family, designed to convert digital control signals into analog outputs that drive field devices such as drives, valves, and actuators in control panels. It provides two analog outputs supporting signal types including 1–5 V, 0–5 V, 0–10 V, ±10 V, 0–20 mA, and 4–20 mA, with a 13-bit resolution (~1/6000) and an approx. 2 ms conversion time per point. The module’s current-output range presents an output load resistance of 350 Ω to 2 kΩ, and power consumption is 40 mA at 5 VDC or 95 mA at 24 VDC. Isolation is via photocouplers (no channel-to-channel isolation) and the unit mounts in a PLC rack as an expansion module in CP1W systems. Dimensions are about 90 × 86 × 50 mm and weight around 200 g. It supports CP1W series integration and is commonly used in process control, temperature regulation, and machine automation requiring flexible voltage and current outputs with stable performance. Common replacements include CP1W-DA041 and CJ1W-DA021, CJ1W-DA041, with CJ1W-DA041 being a related option.
