{"product_id":"allen-bradley-1746-no4i-analog-output-module","title":"Allen-Bradley 1746-NO4I Analog Output Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1746-NO4I is a SLC 500 four-channel analog output module that provides four current-output channels delivering 0 to 20 mA signals to field devices from a PLC backplane, enabling direct analog control of actuators and process equipment in a wide range of automation tasks. Designed for the SLC 500 family, it supports installation in a standard 1746 I\/O rack and is commonly used to drive valves, dampers, and other devices that respond to current-output control signals in batch, manufacturing, or safety-critical processes. Power for the module can be supplied from the SLC backplane or via an external 24 V DC supply, offering installation flexibility where backplane current limits would otherwise constrain output drive. Rockwell Automation lists the 1746-NO4I as a SLC 4 Point Analog Output Module and notes its lifecycle status as discontinued as of April 29, 2021, making it relevant primarily for legacy-system maintenance or projects that can accommodate migration to newer 1746 or modern I\/O families.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658971906350,"sku":null,"price":206.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a87cac4f-667e-4a51-98cd-6384844cf9d8.jpg?v=1769526173","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-no4i-analog-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
