Description
- Dynamic UV Sensor Processing: Specifically engineered to process incoming signal pulses from dynamic self-checking UV flame detectors (such as the Honeywell C7061 series), validating the oscillating shutter cycle to ensure true flame detection.
- Continuous-Duty Operation: Designed for burners firing non-stop for 24 hours or longer, providing safe, uninterrupted flame supervision without requiring daily shutdown cycles for sensor testing.
- Selectable Flame Failure Response Time (FFRT): Supports configurable 2.0-second or 3.0-second FFRT options to comply with specific burner codes, fuel types, and plant safety requirements.
- 7800 Series Controller Integration: Plugs directly into edge connectors on Honeywell 7800 Series Relay Modules (such as RM7800, EC7800, and RM7840) for fast installation and field maintenance.
- Fail-Safe Self-Checking Design: Continuously monitors internal amplifier circuitry and connected sensor components to guarantee fail-safe operation and prevent unburned fuel accumulation from false flame signals.
- Onboard Diagnostic Signal Jacks: Includes front-accessible test points that allow field technicians to measure flame signal voltage (DC) directly using a standard digital voltmeter or microammeter.
- Color-Coded Casing: Enclosed in a distinct red color-coded module housing for easy visual identification and panel organization in industrial control cabinets.

Description
The Honeywell R7861A1026 Dynamic Self-Check UV Flame Amplifier is a solid-state, plugin micro-module designed for continuous-duty commercial and industrial burner applications. Engineered to process signals from dynamic self-checking UV flame detectors, this amplifier monitors the periodic shutter movement of the sensor to continuously verify both flame presence and detector health without interrupting burner operation. Designed for direct insertion into Honeywell 7800 Series relay modules, the R7861A1026 features a selectable 2.0 or 3.0-second Flame Failure Response Time (FFRT), front-panel test jacks for real-time signal diagnostics, and fail-safe component checking to prevent false flame indications in continuous 24/7 process heating and power applications.
Frequently Asked Questions
Which Honeywell burner controls are compatible with the R7861A1026 flame amplifier?
The R7861A1026 plugs directly into Honeywell 7800 Series microprocessor-based burner controls, including the RM7800, EC7800, RM7840, and RM7838 relay modules.
What flame detectors work with the Honeywell R7861A1026 amplifier?
This amplifier is designed to process signals from Honeywell dynamic self-checking UV flame detectors, including the C7061A, C7061F, C7076A, and C7076D series.
How does the dynamic self-checking feature enhance burner safety on the R7861A1026?
The amplifier continually checks for internal sensor and component faults by monitoring the shutter pulse from the UV detector. If a component fails or a simulated flame-out condition fails to register, the amplifier instantly triggers a safety shutdown to prevent unburned fuel risks.
What is the significance of the 2.0 vs. 3.0 second Flame Failure Response Time (FFRT)?
FFRT dictates how fast the amplifier signals the burner control to shut off fuel valves after a flame disappears. Selecting 2.0 or 3.0 seconds allows facility engineers to comply with local combustion safety standards and specific burner fuel hazard ratings.
How do service technicians test flame signal strength on the R7861A1026 module?
Technicians insert standard meter probes into the two flame signal test jacks on the front face of the R7861A1026 module. A minimum reading of 1.25 VDC indicates a stable, reliable flame signal.
