Burner Control System | Honeywell R7120M1019
The Honeywell R7120M1019 is an integrated microcomputer-based burner control system engineered for safe flame safeguard management in industrial and commercial heating applications. Combining a relay module, flame amplifier, and purge card capability into a single compact chassis, it provides automatic sequencing, flame monitoring, and safety shutoff for single-burner gas, oil, or combination fuel systems.
System Integration and User Interface Options
The R7120M1019 operates on 120 VAC and connects into standard burner control wiring subbases. System monitoring and setup are supported through the optional S7800A1142 Keyboard Display Module (KDM) and Data Control Bus Module, which allow real-time operational status display, parameter navigation, and remote display panel mounting options.
When paired with the S7800A1142 KDM, the module supports a programmable postpurge function to clear remaining combustion gases following burner shutdown. Local diagnostics are assisted by a blinking fault code sequence on the POWER LED to accelerate troubleshooting during alarm conditions.
Electrical Protection and Operating Envelope
The unit supports a maximum total connected load of 2000 VA and requires external circuit protection via a 15 A fast-blow fuse (Type SC or equivalent). Internal power consumption is limited to 10 W maximum to ensure thermal stability across a broad ambient operating range from -40 to +66 deg C.
