{"product_id":"allen-bradley-1756-dhrio-digital-high-density-remote-i-o-module","title":"Allen-Bradley 1756-DHRIO Digital High-Density Remote I O Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-DHRIO is a Data Highway Plus (DH+) and Remote I\/O bridge and scanner designed for ControlLogix systems. As a two-port module, it provides two DH+ ports and functions as a Remote I\/O scanner on a DH+\/RIO network, enabling data exchange between a ControlLogix controller and both DH+ devices and Remote I\/O racks. It is designed to mount in a 1756 ControlLogix chassis and to interface with DH+ and Remote I\/O networks via two channels and three terminal blocks. Rockwell describes the 1756-DHRIO as a DH+\/RIO bridge that can connect legacy DH+ devices—such as PLC-5 or SLC 500 controllers—to a ControlLogix rack—facilitating data transfer and control signaling across networks. The module is part of Rockwell's ControlLogix I\/O family and serves to integrate older DH+ networks with modern CLX systems. Note that Rockwell has announced the discontinuation of the ControlLogix DH Plus\/RIO Communications Module line—including the 1756-DHRIO—effective December 31, 2024, with no further sales after that date.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658913841454,"sku":null,"price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ce00d2e1-1a49-4231-b296-dafe2b386317.jpg?v=1769525456","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-dhrio-digital-high-density-remote-i-o-module","provider":"PLG Automation ","version":"1.0","type":"link"}
