{"product_id":"allen-bradley-1756-dhrio-rio-interface-module","title":"Allen-Bradley 1756-DHRIO RIO Interface Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1756-DHRIO is a Data Highway Plus\/Remote I\/O interface module for ControlLogix backplanes, providing two DH+ channels (A and B) to bridge a DH+ network with a ControlLogix processor and Remote I\/O devices. It supports DH+ messaging between devices on a DH+ network and enables data exchange with Remote I\/O scanners, effectively allowing legacy DH+ installations to integrate with modern ControlLogix systems. The module is installed in a 1756 I\/O chassis and acts as the bridge between the DH+ network and the ControlLogix backplane, enabling communication with DH+ devices such as PLC-5 or SLC 500-era equipment that still use DH+. Rockwell’s documentation identifies the 1756-DHRIO family as the DH Plus\/RIO communication interface module for ControlLogix, and as of December 31, 2024, Rockwell announced the DH Plus\/RIO module line is discontinued and no longer available for sale.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657392095534,"sku":null,"price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_58dd588f-995f-4d7b-aafc-e6743e835785.jpg?v=1769468496","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-rio-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
