As part of the SLC 500 family, this 4-slot chassis provides a separate expansion backplane that ties into your main rack via 1746 rack interconnects, commonly using expansion cables such as 1746-C7 or 1746-C9 to bridge the gap between racks. The 1746-A4 is designed for expansion in industrial control setups where additional I\/O capacity is required while keeping the processor and core I\/O in the main chassis. In typical configurations, the 1746-A4 sits adjacent to the main SLC rack, accepts up to four individual 1746 I\/O modules, and relies on the backplane to deliver common power and signaling to those modules through the extension cables. This chassis is specifically marketed for SLC 500 systems and forms a standard option when planning scalable modular I\/O in legacy Rockwell Automation installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658987143470,"sku":null,"price":1595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5d9d2408-ceb4-44f4-b2e1-b727c8847b43.jpg?v=1769526319","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-a4-slc-500-4-slot-rack-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
