HONEYWELL 51199942-300 C300 System Backup Battery

Description

The HONEYWELL 51199942-300 is a memory backup component and backup battery designed exclusively for the HONEYWELL C300 System. Classified as an integrated circuit (IC), this unit features a 3.6V lithium primary battery core, with the product constructed using 100% imported components with domestic battery cells. As a critical system support component, it enables memory retention for the C300 system during power interruptions. The associated control unit configuration includes at least two CF9 control firewall modules and two C300 controller modules, delivering Level 1 redundancy to enhance system reliability. It integrates with a PGM module that facilitates connection to underlying PROFIBUS DP/PA networks, supporting seamless communication with field-level devices. The system also includes built-in overcurrent protection: when an overcurrent condition occurs in an output circuit, the specific output is shut down, switches to manual mode, and generates an overcurrent soft fault. This protection is channel-specific, affecting only the impacted channel while leaving unaffected channels operational, preventing widespread system disruption. It works in conjunction with Experion PKS software for control engineering and Experion FDM software for asset management as part of the full C300 system architecture.
