It is designed to host two I\/O modules beyond the processor’s built-in I\/O, extending the controller’s input and output capabilities without replacing the main CPU. The chassis includes an internal power supply to support both slots, keeping the expansion I\/O powered and synchronized with the central controller. This expansion rack is used in stand-alone automation setups, machine panels, or process lines where additional I\/O density is required, and should be paired with a compatible SLC 500 processor and appropriate I\/O modules designed for fixed or modular SLC 500 configurations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659715674414,"sku":null,"price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_243e1d75-69d4-4f1d-9887-785d5d2f1b3e.jpg?v=1769529798","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-a2-slc-500-fixed-io-expansion-chassis-2-slot-rack","provider":"PLG Automation ","version":"1.0","type":"link"}
