Honeywell R7851B1000 Amplifier
The Honeywell R7851B1000 Flame Signal Amplifier is a solid-state plug-in component engineered for high-performance flame monitoring in industrial and commercial combustion systems. Designed specifically for use with the 7800 Series Primary Safety Control, this unit facilitates reliable optical flame sensing across gas, oil, and coal-fired applications. It is fully compatible with C7927 and C7962 UV sensors, as well as visible light sensors, providing a standard flame signal strength range of 0.0 to 5.0 Vdc. This white-coded amplifier features Ampli-Check circuitry, which performs continuous self-diagnostics to verify signal integrity during the burner run cycle. With a field-selectable flame failure response time (FFRT) of 2 or 3 seconds, the R7851B1000 ensures precise safety shutdowns. This model is technically identical to the R7851B1000/U, serving as a direct drop-in replacement for failed amplifiers in complex burner management systems (BMS).
- Universal Compatibility: Seamlessly integrates with the Honeywell 7800 Series Relay Modules and optical detectors.
- Dynamic Self-Checking: The Ampli-Check feature minimizes downtime by ensuring the amplifier is operating within safe parameters.
- Optimized Response: Selectable 2.0 or 3.0 second FFRT allows for customization based on specific fuel types and local safety codes.
- High Signal Resolution: Provides a clear 0.0-5 Vdc flame signal output for accurate troubleshooting and system tuning.
Common Questions
How do I test the flame signal strength on the R7851B1000?
Using a standard digital volt-ohm meter (minimum 20,000 ohms/volt), measure the DC voltage across the 7800 Series Keyboard Display Module or the test jacks. A stable reading between 1.25 and 5.0 Vdc indicates a healthy flame signal.
Can this amplifier be used with infrared (IR) flame detectors?
No, the R7851B1000 is specifically designed for optical flame sensors including UV and visible light models like the C7927. For IR applications, a specific infrared amplifier must be utilized.
What does it mean if the Ampli-Check identifies a fault?
The Ampli-Check system monitors for component failure within the amplifier itself. If a fault is detected, the safety relay will initiate a safety shutdown to prevent unmonitored combustion, indicating the unit requires replacement.
