Its dual channels, labeled A and B, can be configured for DH+ networks or as Universal RIO operation, enabling the controller to poll, read, and write I\/O data across multiple networks and racks without replacing legacy equipment. Rockwell documentation notes that the 1756-DHRIO can route messages through up to four DH+ networks across three chassis, providing flexible topology options for complex automation systems. As a DH+\/RIO bridge, the module serves as the RIO scanner on its configured channel(s), offering seamless integration between ControlLogix and older Remote I\/O devices while using Studio 5000 or RSLogix 5000 configuration tools. Designed for use in ControlLogix environments, it supports standard remote I\/O addressing, real-time data exchange, and straightforward configuration through Rockwell's engineering software.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658948215086,"sku":null,"price":1088.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cdb0be41-a5fa-4d51-a50a-76165375617b.jpg?v=1769525821","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-digital-high-speed-i-o-module","provider":"PLG Automation ","version":"1.0","type":"link"}
