It supports Data Highway Plus networks and provides multi-network routing capability, allowing a single module to route messages through up to four DH+ networks and across three chassis for complex, multi-hop installations. For Series C (Version 5.2 or later) devices, DH+ baud settings include 115.2 kbaud and 230.4 kbaud, broadening compatibility with varied DH+ configurations. Typical applications include integrating DH+ remote I\/O racks with a ControlLogix controller, connecting legacy DH+ devices to newer networks, and acting as a bridge between DH+ networks and other Rockwell Automation communications within a single ControlLogix chassis. As part of the 1756 family, the 1756-DHRIO expands I\/O connectivity by providing a dedicated DH+ interface that complements other I\/O modules, enabling reliable data transfer and messaging for automation tasks that rely on Data Highway Plus networks. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658948346158,"sku":null,"price":96.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c36e84e6-8ae7-41be-a6ee-138827971859.jpg?v=1769525824","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-communication-interface","provider":"PLG Automation ","version":"1.0","type":"link"}
