RA890G1252 | Honeywell Safety Relay

Honeywell · Relays, Contactors & Switches

Description  The Honeywell RA890G1252 is a flame safety relay designed to control gas or oil burner systems through reliable flame monitoring and automatic recycling upon flame loss. With selectable flame failure response times and low standby power consumption, it is a trusted component for safe combustion system management.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Safety Systems Part Number RA890G1252 Subcategory Burner Control Series RA890G Voltage Frequency 50/60 Hz Volt-Ampere Rating 60 Hz: 14 VA max / 12 VA standby 50 Hz: 18 VA max / 17 VA standby Power Consumption 60 Hz: 9.5W max / 3W standby 50 Hz: 10W max / 4W standby Flame Failure Response Time 0.8 or 3 seconds (model dependent) Flame Establishing Period Up to 15 seconds Recycle Time Immediate upon flame loss Weight 3.33 lbs       Information About RA890G1252 The RA890G1252 is an advanced safety relay module built for flame rectification applications in commercial and industrial burners. Operating on standard 50/60 Hz power, it provides fast, dependable response in flame detection with built-in logic for flame loss recycling and safety shutdown. It offers two flame failure response time options—0.8 or 3 seconds—to match application safety requirements, with the 3-second model recommended for non-recycling cutoff systems. The flame establishing period is up to 15 seconds, giving sufficient time for pilot ignition before lockout is triggered. Key Features: Dual Flame Failure Response Options: Selectable 0.8 or 3 seconds for responsive flame monitoring and system compatibility. Immediate Recycle Logic: Automatically recycles upon flame loss, improving system uptime and safety reset behavior. Low Power Consumption: Operates with minimal energy usage—3W (60 Hz) or 4W (50 Hz) in standby. Safe Flame Establishing Period: Allows up to 15 seconds for flame ignition to establish during burner startup. High Reliability: Designed for continuous burner monitoring in high-demand industrial settings. Standard VA Ratings: 14–18 VA maximum depending on frequency, enabling efficient panel integration. Compatible with Rectification Systems: Uses proven flame rectification for detection, eliminating the need for UV tubes or IR sensors. Trusted RA890 Series Performance: Part of Honeywell’s legacy line of flame safety relays with field-proven results. The RA890G1252 helps maintain a safe combustion cycle, responding immediately to flame interruptions and minimizing the risk of fuel buildup.
