Catalog number 1746-SN, it serves as the scanner component within a Remote I\/O (RIO) configuration in the SLC 500 family and manages the communication protocol between the controller and remote I\/O devices. By handling data transfer for inputs and outputs across remote racks, the module enables a scalable I\/O topology without routing every device directly to the central processor. Typical applications include manufacturing lines, packaging lines, and process-control configurations where sensors, actuators, and other I\/O are spread across multiple racks and need centralized control via a single SLC 500 controller. The 1746-SN is installed alongside other 1746-series I\/O modules on the SLC backplane and participates in the standard RIO communication scheme used by SLC 500 systems to coordinate device addressing, data words, and I\/O updates across the distributed network.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658963910958,"sku":null,"price":187.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8a00c206-91d6-4430-9dd9-cb09eff9a326.jpg?v=1769526069","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-sn-i-slc-500-scanner-module","provider":"PLG Automation ","version":"1.0","type":"link"}
