Product Details
The Honeywell 51303948-100, also cataloged as the 51303948-100 Battery Bank Module, operates as a dedicated hardware component for continuous power retention within High-Performance Process Manager (HPM) and Advanced Process Manager (APM) Universal Control Network (UCN) nodes. It provides direct physical execution of 48 VDC power backup through a quick-disconnect connector assembly during primary feed voltage loss.

4-20 mA HART Loop Protocol & DCS Integration
The 51303948-100 battery bank maintains steady-state voltage across internal logic rails and memory buses, preventing memory corruption and communications dropouts across UCN controller racks. Internal channel-to-channel isolation circuits prevent battery bus transients from affecting connected 4-20 mA HART loop protocol field termination assemblies or digital process controllers. This uninterruptible power transition supports continuous telemetry scanning and deterministic process loop execution during plant AC distribution failures.
Frequently Asked Questions
Q: How does the quick-disconnect connector operate during battery maintenance?
A: The disconnect connector allows isolation of the 48 VDC battery backup assembly from the live controller rack without disrupting primary DC power rails.
Q: Is the 51303948-100 battery bank designed for standalone operation or rack installation?
A: The unit is designed to be installed directly into dedicated battery backup rack slots within Honeywell HPM and APM cabinet structures.
Field Installation Guidelines
- Verify that primary DC power buses are operating within nominal limits before connecting the 51303948-100 module to the rack interface.
- Align the battery assembly on cabinet guide rails and slide it into the designated battery rack housing until fully seated.
- Secure the quick-disconnect connector assembly firmly to ensure low-resistance contact and lock retaining hardware.
- Verify polarity and voltage at the terminal connections with a calibrated meter prior to commissioning.
