{"product_id":"allen-bradley-1747-sn-remote-io-scanner-module","title":"Allen-Bradley 1747-SN Remote IO Scanner Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1747-SN Remote I\/O Scanner Module is the SLC 500 system interface that enables an SLC 5\/02, 5\/03, 5\/04, or 5\/05 controller to exchange data with remote I\/O racks over the Remote I\/O (RIO) link. As the scanner in the 1747 Remote I\/O network, it coordinates data flow between the central processor and remotely located 1746 I\/O chassis, using 1747-ASB adapters in the remote racks to connect the I\/O modules to the RIO bus. In RSLogix 500 projects, the 1747-SN is configured to map I\/O addresses across the network and monitor status and diagnostics across the RIO network, making it a key component for legacy AB automation setups that rely on distributed I\/O. The module is installed in the SLC 500 chassis and supports standard RIO communications, enabling centralized control of geographically distributed I\/O while preserving compatibility with older AB hardware.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657303294254,"sku":null,"price":102.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fe43e1be-02ae-4f3b-a539-58031a1bcdfc.jpg?v=1769467708","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-sn-remote-io-scanner-module","provider":"PLG Automation ","version":"1.0","type":"link"}
