Description
The Honeywell R7847A1074 Flame Signal Amplifier FFRT is a plug-in electronic module that processes and conditions flame detector signals for burner management systems used in HVAC combustion equipment. It operates with a flame failure response time of 0.8 seconds, meaning it rapidly evaluates flame presence and transmits a shutdown signal when flame loss is detected within a very short safety window. The amplifier receives input from flame sensors such as rectification flame rods or ultraviolet detectors and converts the signal into a stable DC output for the control module and interfaces with the flame scanner, ignition controller, and safety circuits.
