Each of its eight inputs draws about 8 mA at 12 V or 24 mA at 24 V, enabling reliable sensing of digital field devices across the 12–24 V DC range. The module is intended to wire to three-wire input devices and supports stranded conductors in the 14–16 AWG range; official installation data describe suitable field wiring practices for 1771-IB modules. In practical use, it serves to monitor digital signals from devices like pushbuttons, limit switches, and proximity sensors, feeding PLC-5\/SLC 500 controllers via the module’s backplane. This model is described as a 12–24 V DC input module, aligning with Allen-Bradley’s DC input family for discrete, on\/off signaling in industrial control applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244007182570,"sku":null,"price":2227.0,"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-ib-16-point-dc-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
