{"product_id":"allen-bradley-1746-a2-two-slot-expansion-rack","title":"Allen-Bradley 1746-A2 Two Slot Expansion Rack","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1746-A2 is a compact two-slot expansion rack for SLC 500 fixed I\/O systems, engineered to add two expansion slots to an existing backplane without replacing the main chassis. It functions as an expansion chassis for fixed I\/O units in SLC 500 modular or fixed configurations, allowing up to two I\/O modules to be mounted in the backplane to extend the system’s I\/O capacity. With dimensions of approximately 171 mm high, 80 mm wide, and 145 mm deep (6.73 x 3.15 x 5.71 in) and a nominal weight of about 0.4 kg (1.0 lb), it is designed for back-panel mounting and supports slot fillers to cover unused slots. This expansion rack is typically used in industrial control panels and machine automation environments where two additional I\/O slots are needed within an existing SLC 500 installation, enabling scalable, two-slot I\/O expansion within the original fixed I\/O architecture.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658987307310,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bea12882-34cc-44b3-88ca-eba4844529e8.jpg?v=1769526323","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-a2-two-slot-expansion-rack","provider":"PLG Automation ","version":"1.0","type":"link"}
