As a DH+\/RIO interface, it handles Data Highway Plus communications for remote I\/O devices and serves as the gateway for data exchange between the DH+ network and the ControlLogix controller. Typical applications include integrating legacy DH+ Remote I\/O devices into modern ControlLogix systems, enabling remote I\/O data transfer and network bridging within a single chassis. Verified physical and electrical characteristics include an open enclosure and a 1-slot width, with backplane current requirements of 5 V at 1.7 mA and 24 V at 850 mA, a maximum power dissipation of 4.5 W, operating temperature range of 0 to 60 °C (32 to 140 °F), and a unit weight of about 0.64 lb, with the module designed for installation in 1756 ControlLogix chassis. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658948608302,"sku":null,"price":942.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_56b27175-177d-4c27-ae55-1587f02e72fd.jpg?v=1769525829","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhri0-communication-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
