It accepts 10–30 V DC input levels and uses sink input architecture, requiring a source on each input line. The channels are organized as sixteen inputs in eight pairs (1–2, 3–4, 5–6, 7–8, 9–10, 11–12, 13–14, 15–16) for straightforward wiring to buttons, sensors, and switches, with the paired arrangement commonly used in PLC-5 I\/O wiring. The module interfaces with the 1771 backplane and is compatible with PLC-5 controllers that support 1771 I\/O modules, enabling digital logic in ladder logic or function blocks to react to real-time field conditions. Typical applications include machine automation, process monitoring, and safety interlocks where reliable DC input signals must be captured by the PLC.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244007936234,"sku":null,"price":798.0,"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-ibn-16-point-dc-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
