Description
The Honeywell RM7895C1012 serves as the primary RM7895C1012 Burner Control Unit utilized to execute safety sequence timing and dynamic flame monitoring across 7800 SERIES combustion platforms. It mounts directly to a wiring subbase to supervise pre-purge timing, interrupted pilot ignition, delayed main fuel valve energization, and safety interlock circuit status during burner operation.
Suffix Breakdown & Model Matrix
- RM7895C1012: Standard production model featuring nonvolatile memory, interrupted pilot functionality, delayed main valve logic, and selectable pilot flame establishing period.

Process Control and DCS Interface Features
The module provides robust channel-to-channel isolation between internal microprocessor circuits, low-voltage flame signal sensor inputs, and line-voltage output contacts. Signal parameters, lockouts, sequence states, and flame voltage telemetry pass over the integrated ControlBus serial interface to plant DCS networks or supervisory automation systems without introducing signal degradation or loop interference.
Frequently Asked Questions
Q: What is the primary benefit of the nonvolatile memory built into the RM7895C1012?
A: Nonvolatile memory retains all critical lockout history, operating status, and system parameters even after total loss of main input supply power.
Q: Can the RM7895C1012 relay module operate without an external plug-in purge card?
A: No, the unit requires an ST7800 plug-in purge timer card, a compatible flame signal amplifier, and a Q7800 subbase for proper functional operation.
Field Installation Guidelines
- Turn off main line power supplied to the Q7800 subbase prior to installing or removing the module.
- Check subbase terminal connections to confirm compliance with 120 VAC power and output load ratings.
- Align rear card-edge connectors carefully into the subbase receptacle and press straight until seated, securing all captive retaining screws.
- Separate low-voltage flame detector cables and ControlBus communication lines from high-voltage ignition leads by a minimum distance of 150 mm.
