Omron C200H-OC221 Output Unit

The Omron C200H-OC221 Output Unit is a 16-point relay digital output module for Omron C200H SYSMAC PLC systems. It mounts on the C200H backplane (rack-mounted) and provides isolated, normally open relay contacts for each output, enabling drive of external devices such as relays, solenoids, and indicator lamps. Each point switches up to 250 V AC or 30 V DC and is rated at about 2 A per point (relay dependent), with relay-to-PLC isolation to protect the controller from load transients and noise. Designed for industrial automation, it supports applications across manufacturing lines, conveyors, packaging equipment, and process control, and is commonly used for replacement or retrofit in Omron C200H configurations; common replacements include C200H-OC222, C200H-OD212, and CS1W-OC211.
