The module provides galvanic isolation between I\/O and field wiring of up to 500 V ac and 710 V dc, helping protect the controller from faults and enabling flexible wiring topologies. In fixed SLC 500 configurations, the NO4I is powered from the 24 V dc user supply, with a typical module current draw of 55 mA and a maximum of 195 mA at 24 V, per 1746 I\/O documentation. Rockwell Automation lists the 1746-NO4I as discontinued as of April 29, 2021, making it a legacy option and primarily relevant for existing installations or historical reference within the SLC 500 family. \u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659711086894,"sku":null,"price":2755.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1dc18259-52ae-45e1-a8f4-f02cec119a4c.jpg?v=1769529782","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-no4i-slc-500-4-channel-analog-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
