Honeywell R7849A1023 Ultraviolet Flame Amplifier

The R7849A1023 is a solid-state plug-in ultraviolet flame amplifier designed by Honeywell to interface with 7800 Series relay modules in burner management systems. This unit responds to ultraviolet flame detector inputs to verify the presence of burner flames, providing safe and reliable supervision during combustion operations. It plugs directly into compatible relay modules through a keyed printed circuit board edge connector and includes dedicated flame signal test jacks for voltage measurement.

Flame Signal Monitoring and Performance

The amplifier processes flame detector inputs and delivers a quantifiable flame signal strength ranging from 0.0 to 5.0 VDC. Maintenance personnel can utilize the integrated test jacks to monitor flame voltage stability during operation. This model features a standard non-self-checking configuration without dynamic detector self-checking circuitry.
