Honeywell R7861A-1034 SU Ultraviolet Flame Amplifier

The Honeywell R7861A-1034 SU Ultraviolet Flame Amplifier is a dynamic self-check ultraviolet flame amplifier that boosts the ultraviolet flame signal for Honeywell flame-safeguard systems. It interfaces with a UV flame sensor and delivers a conditioned signal to the burner control to enable reliable flame presence detection in gas-fired equipment and to support prompt safety responses if flame is lost. The R7861A-1034 SU configuration identifies a specific member of the R7861A family and is designed for use in combustion-control setups that rely on ultraviolet flame sensing; its built-in self-check capability continuously assesses the flame-detection path during operation. This amplifier is used in burners and boilers that require ultraviolet flame verification as part of a safe, automated fuel-control system.
