{"product_id":"reliance-57c413b-64k-common-memory-module","title":"Reliance 57C413B 64K Common Memory Module","description":"\u003cdiv\u003e\u003cp\u003eThe Reliance 57C413B 64K Common Memory Module is a 64K x 16-bit memory module used in AutoMax and DCS 5000 racks to store shared configuration data. When placed in slot 0 in a rack with multiple Processor Modules, it provides 128K bytes (64K registers) of memory for cross-processor configuration data. The stored data includes definitions of physical I\/O and other system-wide configurations that multiple processors must access, ensuring consistent operation across the rack. It is commonly cataloged as M\/N 57C413B with alternative part numbers including 57C-413B, 57C413-B, and 804112-R, reflecting the Reliance Electric lineage that fed into Rockwell Automation. These modules are used to extend a processor's storage data in AutoMax racks, enabling larger configurations without modifying individual processors. The 57C413B is compatible with legacy Reliance Electric\/Reliance automation systems and is typically employed in multi-processor AutoMax configurations where centralized memory holds the pilot parameters, I\/O maps, and inter-processor definitions.\u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51708582232366,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1a19cfa6-9907-478b-8535-0d725683826b.jpg?v=1770246474","url":"https:\/\/plgautomation.com\/products\/reliance-57c413b-64k-common-memory-module","provider":"PLG Automation ","version":"1.0","type":"link"}
