It plugs into a 1756 backplane in a ControlLogix chassis to enable data exchange between a ControlLogix CPU and DH+ devices or Remote I\/O racks, effectively linking legacy DH+ networks and RIO devices with modern controllers. The module supports DH+ and RIO communication formats, allowing integration of older PLC-5 DH+ networks or RIO devices with ControlLogix systems without replacing field hardware. It is specified with firmware revision 6.3 (F REV. 6.3), reflecting its installed software level. Common applications include migrating legacy DH+ or Remote I\/O installations to ControlLogix, expanding I\/O reach across DH+\/RIO networks, and enabling communication between PLC-5\/DH+ devices and a ControlLogix processor through a single interface module. Designed for installation in an 1756 chassis, the 1756-DHRIO leverages the ControlLogix backplane to support data transfer between DH+ \/ RIO devices and the controller. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657302147374,"sku":null,"price":52.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c6f56169-37cb-47d0-b2ac-95a1301dea02.jpg?v=1769467694","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-rio-communication-interface","provider":"PLG Automation ","version":"1.0","type":"link"}
