Omron Industrial Automation CP1W-16ER Expansion IO Relay Output Unit

The Omron CP1W-16ER expansion IO relay output unit adds 16 independent relay outputs to CP1W-series PLCs, delivering expanded control points for industrial automation in control panels, packaging lines, conveyors, and production equipment. It is designed for CP1E, CP1L, and CP1H controllers, mounts on a DIN rail, and uses screw-terminal connections with relay isolation between outputs. Each of the 16 relay outputs is a normally open contact rated up to 250 VAC or 30 VDC, with a practical load rating of about 2 A per point for resistive loads. The unit is powered through the CP1W system and operates from 0°C to +55°C. Common replacements include CP1W-16ET, CP1W-8ER, and CJ1W-OD211. Typical applications include controlling motors, actuators, solenoids, and other field devices across manufacturing lines, material handling systems, food processing equipment, OEM machinery, where flexible, scalable PLC output expansion is required.
