Honeywell R7861A Series Flame Failure Safety Relay Module
Product Overview
This Honeywell R7861A series flame relay is a dedicated safety control module for industrial burners, used together with UV flame detectors (C7061 series) to continuously monitor combustion flame status. Once flameout occurs, the module will quickly cut off the gas valve within 0.8 seconds to eliminate gas leakage and explosion hazards. Multiple mainstream models are available to match various gas/oil burners, widely used on industrial boilers, heating furnaces, drying ovens and heat treatment equipment.
