WRC 1781-OBXS SLC 500 Output Module

The WRC 1781-OBXS Output Module is a solid-state discrete output module that provides DC switching for multi-channel outputs from PLCs to field devices in industrial automation. It uses optical isolation, LED channel status indicators, and mounts on standard I/O mounting boards to support expansion or replacement of I/O in manufacturing equipment, packaging lines, conveyor systems, and other machine control panels requiring reliable discrete output control. Designed for controlling relays, solenoids, contactors, indicators, and similar field devices, it suits industrial automation and process equipment where stable, efficient digital output switching is essential. Common replacements include WRC 1781-OB5Q and Opto 22 ODC5.
