Each of its inputs is galvanically isolated from the backplane and from other channels, delivering a continuous isolation rating of 250 V for enhanced noise immunity and safety in rugged environments. The 36-pin module accepts either voltage or current signals on its eight isolated channels, with input ranges including -10 to 10 V, 0 to 10 V, 0 to 5 V, and 0 to 21 mA, and it provides 24-bit resolution per channel for precise digital representation. The IF8I can operate in both non-sourcing and sourcing current modes; in sourcing mode the channel can provide loop power to a connected sensor, while in non-sourcing mode the current input is passive. Total backplane power requirements are about 4.6 W in non-sourcing voltage mode and up to about 10.6 W when sourcing, reflecting the added burden of loop-powered operation. This module plugs into a ControlLogix backplane and communicates with the controller over the standard 1756 I\/O backplane. Typical applications include monitoring analog sensors and transducers that output voltage in the -10 to 10 V range or current signals up to 21 mA, enabling isolated, precise data acquisition for process control, safety interlocks, and diagnostics.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659668291886,"sku":null,"price":638.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bb734770-c624-4a0f-bfb2-5ca64c102c65.jpg?v=1769529700","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-if8i-isolated-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
