Omron CJ1W-DA041 CJ Series Analog Output Unit 4 Channels 12‑bit

Omron CJ1W‑DA041 is a Special I/O Unit for SYSMAC CJ series PLC systems. It provides 4 analog output channels, each independently configurable for voltage or current signals. Intended for applications requiring precise analog control, such as variable speed drives, proportional valves, and SCR power controllers. Screw terminal connection.

Applications:

• Process control (pressure, flow, level regulation via 4‑20 mA loops)

• Machine automation (speed reference to servo drives and VFDs)

• Multi-zone temperature control with analog‑fired SCR power controllers

• Proportional valve positioning in hydraulic or pneumatic systems

• Analog signal simulation or test equipment interfacing

Core Specifications:

• Outputs: 4 analog outputs (independently configurable)

• Output ranges: 1 to 5 V, 0 to 5 V, 0 to 10 V, –10 to 10 V, 4 to 20 mA

• Resolution: 1/4000 (12‑bit)

• Conversion time: 1 ms per point (at 1/4000 resolution)

• Accuracy: voltage ±0.3% of full scale, current ±0.5% of full scale (at 25 °C)

• External power supply: 24 V DC (200 mA max.)

• Current consumption: 5 V DC at 0.12 A from PLC backplane

• Connection type: Removable screw terminal block

• I/O connection type: Screw terminal (28‑point removable terminal)
