Its function is limited to maintaining the specified memory and clock functions; it does not provide operating power for the controller processor, I\/O modules, or external field circuits.\u003c\/p\u003e\n\u003cp\u003eThe lithium cell uses a nominal 3.0 VDC output and a BR2032-type form factor. The specified operating temperature range is -30 deg C to +85 deg C, with a stated self-discharge rate below 1% per year at room temperature.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What functions does the T9905 support during a controller power interruption?\u003cbr\u003eA: It provides backup power for the AADvance Controller RTC and static RAM data retention circuitry. It does not power the controller processor or field I\/O.\u003c\/p\u003e\n\u003cp\u003eQ: What battery chemistry and nominal voltage are specified for the T9905?\u003cbr\u003eA: The supplied specification identifies a Polycarbon Monofluoride Lithium BR2032-type cell with a nominal voltage of 3.0 VDC.\u003c\/p\u003e\n\u003cp\u003eQ: Can the T9905 be treated as a controller power supply?\u003cbr\u003eA: No. The T9905 is a backup battery module intended for RTC and memory retention functions during loss of the controller's primary power.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the T9905 only in the designated battery position of the compatible AADvance Controller assembly. Verify controller power isolation before battery replacement or installation according to the applicable AADvance maintenance procedure.\u003c\/p\u003e\n\u003cp\u003eObserve battery polarity and prevent conductive tools or loose hardware from shorting the cell terminals. Keep the battery circuit separated from field signal wiring and other conductors that could introduce mechanical stress or accidental contact.\u003c\/p\u003e\n\u003cp\u003eDo not substitute a cell with different chemistry, voltage, or physical configuration unless the applicable ICS Triplex documentation explicitly permits the substitution. Verify the installed battery type and condition during controller maintenance.\u003c\/p\u003e","brand":"ICS Triplex","offers":[{"title":"Default Title","offer_id":44049013375066,"sku":"T9905","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/ICSTriplexT8451_3445fbb8-db44-42db-93bf-29e56cbee666.jpg?v=1788514868","url":"https:\/\/www.plcmasters.com\/products\/ics-triplex-t9905-backup-battery-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
