Honeywell 51454475-100 Series 8 C300 RAM Charger Module
The Honeywell 51454475-100 is a Series 8 RAM Charger Module designed for the Honeywell Experion PKS C300 distributed control system. It provides backup power to preserve volatile RAM memory and configuration data during primary power interruptions. Operating with a dedicated NiMH battery pack (part number 51199942-300), this module connects to the C300 controller via specialized battery charging cables to support up to two controllers in industrial automation environments.
Memory Backup and Power Architecture
The module operates via 24 VDC power-system cables and supports redundant power supply inputs through a combination cable arrangement. It uses a rechargeable 3-cell Nickel-Metal Hydride battery pack to maintain memory retention when normal controller power is unavailable. Battery status is continuously monitored through the Experion system's soft failure alarm functionality, ensuring operators are alerted to potential backup issues.
Mechanical Integration and Installation
Installed adjacent to the associated C300 controller I/O Termination Assembly (IOTA) within the Series 8 cabinet infrastructure, the unit uses dedicated 30-inch or 84-inch battery charger cables for controller connection. Its compact single-slot design allows direct integration into existing C300 assemblies without requiring complex wiring modifications.
