It communicates with the host processor via M1 (input) and M0 (output) files and supports mapping of discrete I\/O into the processor’s data image, with configuration available through RSLogix 500 and RSNetWorx as described in the device manual. In standard RSLogix 500 configurations, the 1747-SDN presents a fixed I\/O image of 16 input words and 16 output words (32 words total) to the controller, though data organization can be adjusted in the I\/O table by project settings. Power and electrical requirements specify a 5-24 VDC supply with current draw typically in the 90–500 mA range, and the module operates on DeviceNet networks that provide 24 V nominal field power. The 1747-SDN is part of Allen-Bradley’s SLC family DeviceNet support, with catalog variants such as 1747-SDN\/D listed in distributor catalogs; it is commonly used with SLC 5\/02 or higher processors. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658955522350,"sku":null,"price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_59a8fe87-9628-4b2e-90c6-b5138cfdb348.jpg?v=1769525927","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-sdn-digital-input-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
