Allen-Bradley 1771-OW Selectable Contact Output Module

Allen-Bradley 1771-OW Selectable Contact Output Module is an eight-channel, digital relay output module designed for PLC-5 1771 I/O racks. It uses electromechanical relays to switch field loads at 120V AC and offers a selectable contact configuration across its eight outputs, enabling straightforward integration with devices such as relays, lamps, solenoids, or other 120V loads controlled by the PLC-5 processor. The module occupies a single 1771 I/O slot and communicates on the 1771 I/O backplane, delivering independent control of eight discrete field connections. Widely catalogued and referenced by distributors as a legacy part, the 1771-OW is noted as discontinued in current supplier listings. Compatible with PLC-5 controllers and 1771 I/O racks, this module provides a simple, field-proven means to implement relay switching without external relays on a per-channel basis.
