{"product_id":"allen-bradley-1756-dhrio-controllogix-communication-interface","title":"Allen-Bradley 1756-DHRIO ControlLogix Communication Interface","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-DHRIO is a two‑channel DH+ \/ Remote I\/O communication interface for ControlLogix that plugs into a CLX backplane to bridge DH+ networks with a ControlLogix processor. Each of its two ports can be configured as a DH+ gateway or universal Remote I\/O, enabling data exchange between DH+ devices and remote I\/O racks or PLCs controlled by a CLX system. The module is powered from 24 V DC (C01 24VDC) and occupies a single chassis slot, functioning as a DH+ gateway and remote I\/O scanner within the ControlLogix backplane. Rockwell documentation positions the 1756-DHRIO as a Data Highway Plus \/ Remote I\/O communication interface capable of routing messages between DH+ networks and remote I\/O devices. Typical use cases include migrating legacy PLC-5\/SLC 500 DH+ networks to ControlLogix and serving as a DH+ gateway for remote I\/O racks, allowing legacy DH+ devices to be integrated into a modern CLX control system. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657299919150,"sku":null,"price":735.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0ff56865-f6d0-41f5-a2e7-878457ce71a4.jpg?v=1769467661","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-controllogix-communication-interface","provider":"PLG Automation ","version":"1.0","type":"link"}
