Product Details
The Honeywell SPS5711 51199931-100, also cataloged as the 51199931-100 TDI Battery Charger, operates as a dedicated hardware component for continuous backup power management and regulated battery charging within Honeywell TDC 3000 networks. Accepting an input voltage range of 24 to 26 VDC, the unit conditions and delivers a regulated 30 to 43 VDC output to downstream battery ports at a continuous rating of 20 A. This module prevents power bus dropouts during primary supply interruptions by maintaining steady-state DC reserve levels across connected control chassis.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation
The SPS5711 51199931-100 incorporates high-efficiency internal power conversion circuits designed to prevent high-frequency switching noise from propagating into sensitive field wiring paths. Internal galvanic channel-to-channel isolation decouples the 24-26 VDC input bus from the 30-43 VDC battery charge loop, suppressing common-mode electrical noise. This structural filtering prevents power rail ripple from causing inductive interference or signal distortion on adjacent 4-20 mA HART loop protocol lines running through shared enclosure raceways.
Frequently Asked Questions
Q: What happens if the input voltage drops below the 24 VDC threshold during operation?
A: The charger logic detects under-voltage conditions and disengages the primary charging circuit to prevent reverse current drain from the battery assembly into the input supply bus.
Q: Can the SPS5711 51199931-100 module be replaced while the TDC 3000 system is powered?
A: Module removal requires isolating the continuous 20 A battery charging output terminals first to eliminate arcing risks across the backplane connector pins.
Field Installation Guidelines
- Slide the module into its designated rack slot until the backplane power connectors are fully seated and engaged.
- Tighten all mechanical retaining screws on the front panel to establish a solid ground bond with the cabinet frame.
- Route input and output DC power conductors separately from low-level analog and communication cabling to avoid EMI noise coupling.
- Verify that cabinet ambient airflow pathways remain unobstructed to ensure heat dissipation does not exceed the +60 deg C thermal rating under full 20 A continuous load.
