Honeywell TC-BATT03 (51199942-300) — DCS Controller Backup Battery | TotalPlant Solution Platform
Engineering Background
The Honeywell TotalPlant Solution (TPS) is a distributed control system platform widely deployed in refining, petrochemical, power generation, and continuous-process industries. Its controller nodes rely on onboard lithium backup batteries to preserve SRAM-resident configuration data, I/O maps, and control logic during power interruptions. Loss of battery integrity can result in controller cold-start failures, configuration loss, and unplanned process shutdowns — making timely battery replacement a critical preventive maintenance task.
Product Positioning
The TC-BATT03 (Honeywell part number 51199942-300) is the OEM-specified backup battery for TPS controller modules. Konmask.com supplies this component as a direct-replacement, factory-grade part — fully traceable, tested, and ready for field installation. Suitable for both scheduled PM cycles and emergency replacement scenarios.

System Architecture & Signal Flow
Within the TPS architecture, controller modules maintain active process control logic and I/O configuration in volatile SRAM. The TC-BATT03 provides continuous low-current backup power to this memory subsystem. During a main power interruption or controlled shutdown, the battery sustains SRAM content — allowing the controller to resume operation from its last known state upon power restoration, without requiring a full cold-start reconfiguration cycle. Battery voltage monitoring circuits within the controller generate low-battery diagnostic alarms, enabling proactive replacement scheduling before data integrity is compromised.

Technical FAQ
Q: Is TC-BATT03 the same as 51199942-300?
A: Yes. TC-BATT03 is the Honeywell catalog part number; 51199942-300 is the manufacturing/drawing reference number. Both designate the identical component.
Q: How do I know when the battery needs replacement?
A: The TPS controller generates a low-battery diagnostic alarm in the system console. Additionally, Honeywell recommends proactive replacement per the PM schedule regardless of alarm status.
Q: Can this battery be shipped internationally?
A: Lithium batteries are subject to IATA/ICAO transport regulations. We comply with all applicable shipping requirements. Contact us for international freight options and documentation.
Q: Do you offer volume pricing for MRO contracts?
A: Yes. Contact support@konmask.com with your annual volume estimate for a dedicated quotation.
Q: What is the shelf life of an unused TC-BATT03?
A: Lithium batteries typically retain charge for 5–10 years in proper storage conditions (cool, dry, away from direct sunlight). Consult Honeywell documentation for official shelf-life specifications.
