Constant battery voltage supervision prevents data loss in volatile memory locations across host controllers, maintaining data integrity for deterministic Profinet or EtherNet\/IP deterministic networks during primary power interruptions. The hardware layer functions fully independent of firmware flash compatibility revisions, ensuring continuous operational protection.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What battery type is supported by the SB171 charging circuit?\u003c\/p\u003e\n\u003cp\u003eA: The module is designed specifically to charge and maintain a 12 V, 4 Ah Nickel-Cadmium (NiCd) battery assembly.\u003c\/p\u003e\n\u003cp\u003eQ: How is the SB171 module mechanically integrated into the system?\u003c\/p\u003e\n\u003cp\u003eA: The module installs directly into the subrack chassis slot, interfacing with backplane power rails through standard rack edge connectors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower De-energization: Ensure subrack power is disconnected prior to inserting or removing the power supply module.\u003c\/li\u003e\n\u003cli\u003eSlot Alignment: Guide the SB171 module along the subrack mounting rails until backplane power connectors mate fully.\u003c\/li\u003e\n\u003cli\u003eFastening: Tighten top and bottom retaining screws to ensure proper earth bonding and mechanical retention within the rack.\u003c\/li\u003e\n\u003cli\u003eBattery Wiring: Connect external 12 V NiCd battery terminals maintaining strict polarity alignment to avoid internal fuse trip or charging circuit fault.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53257286451509,"sku":"SB171 3BSE004802R0001","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/SB1713BSE004802R0001.png?v=1786075153","url":"https:\/\/www.5gplc.com\/products\/abb-sb171-3bse004802r0001-backup-power-supply","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
