Honeywell 51454475-100 Series 8 RAM Charger Module

C300 memory-backup RAM Charger Assembly supporting up to four physical Series 8 controllers.

Product Identification

Honeywell 51454475-100 is the Series 8 C300 RAM Charger Assembly used to provide backup power for C300 program memory during loss of normal controller power.

One assembly supports connections for up to four physical Series 8 C300 controllers. The module is normally installed near the associated C300 IOTAs and connects through the approved memory-backup cables.

The RAM charger is an optional controller-memory backup component; it does not replace cabinet UPS design, controller redundancy or project checkpoint procedures.

Functions

  • Supplies standby energy to preserve C300 program memory during loss of normal power.
  • Distributes memory-backup output to as many as four physical controllers.
  • Accepts redundant input power through the approved combo-cable arrangement.
  • Reports battery-status degradation through the Experion soft-failure mechanism.
  • Supports cabinet layouts with multiple C300 controllers when cable length and loading are engineered.

System Integration

  • Mount the RAM charger adjacent to the associated C300 IOTAs where practical.
  • Use only the documented 30-inch or 84-inch memory-backup cable for each controller connection.
  • Account for the number of connected controllers because hold-up duration decreases as controller count increases.
  • Include RAM charger status in maintenance displays and alarm-response procedures.
  • Confirm cabinet power isolation and hazardous-location requirements before connecting or disconnecting hardware.

Applications

  • C300 memory retention during temporary power loss.
  • Cabinets containing one to four physical Series 8 C300 controllers.
  • Redundant controller installations requiring separate memory-backup planning.
  • Process plants where controlled recovery after cabinet-power interruption is required.

Lifecycle

Record the RAM charger model, battery condition, connected controller count and cable part numbers in the cabinet maintenance file.

Investigate any RAM charger battery-status soft failure promptly and plan maintenance within the plant change-control process.

Hold-up time is a design value based on connected-controller count; field condition, battery age and maintenance status must be considered during lifecycle planning.

FAQ

Q1. What does 51454475-100 do?
It supplies backup power for Series 8 C300 program memory during loss of normal controller power.
Q2. How many controllers can it support?
Honeywell specifies connections for up to four physical Series 8 C300 controllers.
Q3. Does adding controllers change hold-up time?
Yes. The documented hold-up time decreases from 110 hours for one controller to 27.5 hours for four controllers.
Q4. Which cables are specified?
Honeywell lists 51202330-300 for 30 inches and 51202330-200 for 84 inches.
Q5. Does it replace a cabinet UPS?
No. It is a controller-memory backup assembly, not a general cabinet uninterruptible power supply.
Q6. How is battery condition monitored?
The architecture supports an Experion soft-failure alarm for RAM charger battery status.
