It mounts in a 1746 backplane and uses a removable terminal block (1746RT25G) for wiring; Belden 8761 or equivalent cable is recommended, with up to two 14 AWG conductors per terminal. The module includes nine green indicators—one for each of the eight channels and a module-status LED—to convey channel and overall status. For wiring, the recommended loop impedance is 40 ohms max for voltage-mode inputs (with source impedance under 10 ohms) and 250 ohms max for current-mode inputs. Discontinued as of September 30, 2024, the NI8 remains a legacy option for maintaining or repairing older SLC 500 systems that require eight analog inputs in a single card, and it is typically used to monitor process signals such as temperature, pressure, or flow from analog sensors feeding into the PLC.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658972299566,"sku":null,"price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_370fa6d9-1d82-4608-b4f2-6d62da718ece.jpg?v=1769526184","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ni8-8-channel-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
