Description
Configured for automatic flame safeguard control and programmable post-purge sequence timing in 7800 SERIES burner installations, the Honeywell RM7897C1000 (RM7897C1000 Control) provides direct physical/electrical execution. It directly controls safety shutoff valves, ignition transformers, draft fans, and auxiliary interlock loops to deliver fail-safe sequencing during burner startup, operation, and shutdown sequences.

Process Control and DCS Interface Features
The module provides isolated digital outputs to drive dynamic self-checking flame detectors and primary safety shutoff valves via internal heavy-duty relay contacts. Robust channel-to-channel isolation separates line-voltage load outputs from low-voltage micro-ampere flame sensor inputs. Data exchange with host DCS or PLC automation systems operates over a dedicated serial ControlBus network, transmitting diagnostic codes, sequence status, and real-time flame signal strength without compromising hardwired safety trip circuits.
Frequently Asked Questions
Q: How is the post-purge timing programmed on the RM7897C1000 control module?
A: Programmable post-purge duration is configured using an optional S7800 Keyboard Display Module connected directly to the front serial port of the RM7897C1000.
Q: Are plug-in accessory cards required for operation?
A: Yes, the RM7897C1000 requires a plug-in ST7800 purge timer card, a compatible flame signal amplifier module, and a Q7800 series wiring subbase for complete hardware assembly.
Field Installation Guidelines
- De-energize all power lines feeding the Q7800 wiring subbase before attempting module mounting or terminal service.
- Confirm subbase terminal assignments align with the 120 VAC main supply and external load current ratings prior to system startup.
- Seat the module vertically onto the subbase, tightening the captive mounting screws to ensure reliable ground continuity and vibration resistance.
- Route flame sensor wiring and ControlBus communication cables in dedicated conduits separated from high-voltage ignition leads by at least 150 mm.
