WRC 1781-A16H Discrete IO Relay Mounting Board

The Western Reserve Controls (WRC) 1781-A16H Discrete I/O Relay Mounting Board provides 16-channel discrete digital I/O interface for organizing and mounting slim/miniature I/O modules within PLC and machine control panels. This panel-mounted board accepts 1781-Series Slim and Miniature I/O Modules, uses a 50-pin IDC header for the logic-side connection, and features individually isolated power-side points with logic-supply compatibility of +5VDC, +15VDC, or +24VDC. Wiring is compatible with insulated wire with stripped ends or ferrules, and common applications include manufacturing equipment, conveyors, packaging machinery, and process automation where relay interfacing and control-panel expansion, retrofit projects, or replacement of damaged I/O mounting assemblies are needed. The module is UL Recognized and CE Compliant.
