Description
The Honeywell R7847B1064 is a professional-grade Flame Signal Amplifier engineered for reliable flame detection in commercial and industrial burner control systems. Designed to work seamlessly within Honeywell’s burner management ecosystem, this amplifier delivers fast, accurate flame signal processing to help protect equipment and ensure safe combustion operation.
Ampli-Check Diagnostic Technology
The R7847B1064 features Honeywell’s Ampli-Check function, which continuously verifies the integrity of the flame signal amplifier circuit. This self-checking capability provides an added layer of safety assurance, confirming that the amplifier is operating correctly during every burner cycle — not just when a flame is present.
Flame Failure Response Time
- Selectable flame failure response time of 0.8 second or 1 second
- Fast response helps minimize fuel release in the event of unexpected flame loss
- Suitable for applications requiring tight safety timing compliance
