The Honeywell 51199932-200 RAM Charger Assembly provides standby power for Series 8 C300 controller program memory. One assembly can support up to four physical C300 controllers and reports battery status through the Experion power-system alarm path.
- Backs up C300 program memory
- Supports as many as four physical controllers
- Accepts redundant power-supply inputs through the combo cable
- Provides battery-status alarm integration
It handles Standby memory-backup power and RAM-charger battery-status indication; it does not terminate process measurement channels. The documented compatible components are Series 8 C300 controllers, associated C300 IOTAs, and Honeywell cables 51202330-100 (0.7 m) or 51202330-200 (2 m).
Important Notice: Current availability and the RP marking must be confirmed from Honeywell order records and the physical nameplate.

Read and follow Honeywell Series 8 Controller and I/O Specification S803-150-520 and the applicable Honeywell installation instructions before use. Verify the exact complete ordering code from the physical nameplate.
1Verify both order codes and the RP marking on the nameplate.
2Use only the documented 51202330 cable length for the cabinet layout.
3Record the number of connected C300 controllers because hold-up time changes with load.
4Confirm alarm-cable termination and battery status before commissioning.
5Do not use this assembly as a field I/O power source.
