The Omron CJ1W-DA08V is a special I/O analog output unit for CJ-series PLC systems, offering eight independent voltage outputs for accurate control of drives, valves, actuators, and other analog devices. Each channel can be configured for common industrial voltage ranges including −10 to 10 V, 0 to 10 V, 0 to 5 V, and 1 to 5 V, making it easy to interface with a wide variety of inverters, servo drives, positioners, and indicators. With 12‑bit resolution (1:4000, scalable up to ±32000 or 1:8000 by setting), the module delivers smooth, fine‑step control suitable for demanding process and motion applications.
The CJ1W-DA08V uses Omron’s CJ I/O bus and is recognized as a special I/O unit, allowing flexible placement within a CJ-series rack while maintaining high‑speed data exchange with the CPU. Built‑in functions such as scaling and offset/gain adjustment (via system settings) simplify engineering and commissioning, reducing the amount of ladder logic needed for signal conditioning. Typical applications include analog speed or torque references for inverters, position or pressure control, level and flow setpoints, and any system that requires multiple independent analog control outputs from a single PLC.
The module features a compact design with a 31 × 90 × 89 mm housing and screw terminal connections, making wiring and panel layout straightforward. A single terminal block serves all eight channels, which helps keep panel space usage and wiring complexity low. With a conversion time of 4000 ms per unit (configurable mode) and robust Omron industrial build quality, the CJ1W-DA08V is well suited for OEM machinery and process systems that demand reliable, repeatable analog output performance.
