Omron CJ1W-AD081-V1 Analog Input Unit

The Omron CJ1W-AD081-V1 is a compact 8-channel analog input unit for CJ-series PLCs, supporting both voltage and current input ranges. Designed as a special I/O unit, it enables accurate monitoring of process variables such as pressure, temperature (via transmitters), or flow signals in industrial control systems.

The unit accepts standard signal levels including 1–5 V, 0–10 V, –10 to +10 V, and 4–20 mA, with a resolution of up to 1:8000 (13-bit). Featuring screw-type terminal connections, it is ideal for stable field wiring in panels and machinery.
