Key technical specs include the DH-485 remote I\/O protocol up to 115.2 kbaud, backplane mounting in a 1747 rack, status LEDs for run, error, and communication, and mounting options on DIN rail or via a PLC rack, with power supplied through the PLC backplane. This module is compatible with SLC 500 and PLC-5 processors with appropriate firmware and supports 1794 FLEX I\/O (with scanner support) for expanded I\/O networks. Common replacements include the Allen-Bradley 1785-DN2 (Data Highway Plus interface) and 1794-SCNR2 (FLEX I\/O scanner), or Ethernet\/IP-based remote I\/O modules.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658954834222,"sku":null,"price":535.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/14.webp?v=1775019985","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-sn-plc-remote-i-o-scanner-module","provider":"PLG Automation ","version":"1.0","type":"link"}
