It connects to the CS31 system bus and accepts 24 V DC digital inputs, enabling the controller to read on\/off signals from field devices such as limit switches and proximity sensors. This I Unit provides 0–24 V level compatibility for reliable sensing in decentralized automation setups, helping to wire sensors directly to the controller without a separate local PLC channel. Ideal for applications where expanding the central controller’s input capability is required in compact industrial control cabinets.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656786510126,"sku":null,"price":73.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bb965a2e-74f6-4ebd-b3e7-c8551aa377f3.jpg?v=1769463494","url":"https:\/\/plgautomation.com\/products\/abb-gjr5251400r3202-advant-controller-31-i-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
