It draws power from the backplane’s +5 V supply for TTL logic and includes a protective fuse to guard both the +5 V rail and input terminals if voltages exceed about 6 V DC or are reversed\/AC. The backplane current load is typically around 130 mA, and the module is specifically described as an 8-point TTL input module within Allen-Bradley’s 1771 I\/O family. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244009115882,"sku":null,"price":159.0,"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-igd-8-point-digital-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
