{"product_id":"reliance-electric-57552-4b-drive-controller-module","title":"Reliance Electric 57552-4B Drive Controller Module","description":"\u003cdiv\u003e\u003cp\u003eThe Reliance Electric 57552-4B Universal Drive Controller Module is a Distributed Power System (DPS) UDC card designed for use in an AutoMax rack to control one or two drives via ports A and B, with a fiber-optic link to two PMIs for high-speed, optically isolated communication. It contains 256 KB of non-volatile flash memory, 512 KB of SRAM, and 4 KB of dual-port SRAM to store and execute drive parameters in real time, and it provides two communication ports (COMM A and COMM B) for networked operation. In typical AutoMax installations, up to 10 UDC modules can be installed per rack, enabling control of as many as 20 drives, and the module is compatible with drives configured through the Configure Parameters workflow using the relevant AutoMax software; the 57552-4B is commonly found labeled as 57552-4 or O-57552 across catalogs. Fault indication is provided by LEDs such as DRV A FLT and DRV B FLT to alert on channel faults. This module originally shipped as part of Reliance Electric’s AutoMax line and, while it remains available from some third-party vendors, it has been discontinued by the manufacturer and is not actively supported by Reliance\/Baldor\/ABB in current product lines. \u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46285440319722,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/reliance-electric-57552-4b-drive-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
