Honeywell R7861A Series Flame Failure Safety Relay Module
Product Overview
The Honeywell R7861A series flame relay is a dedicated safety control module for industrial burner combustion systems. It works together with Honeywell C7061 UV flame probes to continuously monitor the flame status of gas and oil burners. When accidental flameout occurs, the module will rapidly trigger the gas valve interlock and cut off fuel supply within 0.8 seconds to eliminate gas leakage and combustion explosion hazards. Multiple mainstream complete models are available to match various industrial burners, widely applied to gas boilers, heating furnaces, drying production lines and heat treatment equipment in refineries, chemical plants and manufacturing factories.
Core Product Advantages
Complete Full Series Model Supply All mainstream Honeywell flame relay models are in sufficient stock: R7861A1034, R7849A1023, R7861A1026, R7847A1025, RM7800L1012, 847A1033 All original official specifications, fully compatible with standard burner control cabinet circuits.
Ultra-Fast Flame Failure Protection 0.8-second ultra-fast response to flame loss signals, instant interlock shutdown of gas supply, fully meets safety specifications of industrial heating furnace and boiler operation.
Wide Ambient Temperature Adaptability Operating temperature range: -40°F ~ 140°F (-40℃ ~ 60℃), stable signal output without drift or failure under high-temperature workshop conditions close to burners.
Convenient Plug-And-Play Installation Integrated card slot pin terminal structure, plug-in design without complicated wiring, greatly shorten on-site burner maintenance and replacement time.
