It accepts control data from the backplane as an 8-bit word, energizing or de-energizing each of the eight outputs to drive relays, solenoids, or other field devices connected to the module’s terminals. This 1771-OW variant is part of a broader line that includes related models such as 1771-OWNA and 1771-OW16, reflecting the family’s range of 8- and 16-point configurations and associated form factors while maintaining compatibility with standard 1771 backplane wiring and mounting in 1771 I\/O chassis. Common applications include panel automation, machine control, and centralized I\/O subsystems where reliable, isolated switching of external circuits is required and where a compact, plug-in module can be integrated directly into existing Rockwell 1771 architectures. The module’s relay-based outputs provide a straightforward interface for controlling external loads from a Rockwell control program, preserving the familiar 8-bit output addressing scheme and enabling scalable expansion of the PLC-5\/SLC 500 control network without altering the core logic. In sum, the 1771-OW delivers eight discrete relay contacts controlled by a single 8-bit word, offering a robust, field-wirable solution for expanding digital output capacity within the 1771 ecosystem. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244015800554,"sku":null,"price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-ow-8-point-dc-output-module","provider":"GTG Hardware","version":"1.0","type":"link"}
