Product Description

Description

The Honeywell 51303948-100 is a dedicated 48 Vdc Battery Backup Module engineered specifically for Honeywell Distributed Control Systems (DCS), including applications involving High-Performance Process Manager (HPM) and Advanced Process Manager (APM) architectures. Also designated as model MU-PSRB04, this hardware component acts as an essential uninterrupted power safeguard, automatically stepping in during primary power loss to sustain critical control node operations.

Designed for integration within redundant HPM cabinet configurations, the 51303948-100 module provides dependable backup power to support redundant HPMMs and associated I/O processors. Under full load conditions with a fully charged battery assembly, it delivers approximately 20 minutes of runtime, providing a crucial operational window for controlled system shutdowns, alarm management, or primary power restoration.

This unit features integrated disconnect mechanics to facilitate safer field maintenance procedures and reduce mean time to repair (MTTR). It serves as a vital component for plant engineers seeking to maintain high availability and fault tolerance within legacy or active Honeywell process automation infrastructures.
