Each of the eight outputs is a sourcing (high-side) channel capable of delivering up to 0.5 A, with a per-group limit of 2 A and an overall module limit of 8 A, allowing multiple smaller loads to be driven directly while protecting the power rails; loads connected to the outputs should be wired to the return or 0 V, since the OB N outputs provide voltage and require a sink in the load circuit. As a Series B DC output module, the 1771-OBN is part of the 1771 DC Output Module family designed for PLC-5 systems and is compatible with 1771 I\/O racks that support DC output modules, relying on the 1771 bus interface for addressing and signaling. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244013506794,"sku":null,"price":130.0,"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-obn-8-point-digital-output-module","provider":"GTG Hardware","version":"1.0","type":"link"}
