Honeywell RM7895A1014 Flame Safety Burner Control Module

Configured for safety sequence execution and flame supervision in 7800 SERIES burner installations, the Honeywell RM7895A1014 (RM7895A1014 Flame Safety Burner Control) provides direct physical/electrical execution. It mounts to a standard wiring subbase to directly manage intermittent pilot ignition, safety interlock monitoring, main fuel valve energization, and automated burner sequence logic across industrial combustion systems.

Hardware Specifications

Process Control and DCS Interface Features

The unit relies on internal channel-to-channel isolation to decouple low-voltage micro-ampere flame detection circuits from 120 VAC heavy-duty output relays. Operational sequence timing, real-time flame signal voltage, and historical diagnostic lockout metrics pass through the integrated serial ControlBus connection, enabling direct integration into plant DCS networks and PLC automation architectures without degrading safety interlock loop integrity.

Frequently Asked Questions

Q: What is the functional behavior of the intermittent pilot configuration on the RM7895A1014?

A: The intermittent pilot output remains energized throughout the entire burner run cycle alongside the main fuel valve until the call for heat is satisfied.

Q: Are external plug-in components required to operate the RM7895A1014 module?

A: Yes, full functional operation requires a compatible Q7800 wiring subbase, a plug-in flame signal amplifier, and an ST7800 plug-in purge timer card.

Field Installation Guidelines

1. Lock out and isolate all 120 VAC main power sources prior to inserting or removing the relay module from its Q7800 subbase.
2. Ensure subbase card-edge sockets are clean and that terminal wiring strictly matches local electrical codes and system schematics.
3. Align the rear terminal block straight into the subbase connector, applying even pressure until fully seated, then torque the central retaining screws.
4. Maintain physical separation of at least 150 mm between low-voltage flame sensor lines, ControlBus serial cables, and high-voltage ignition leads.
