Information About RA890F-1262
The RA890F-1262 is part of Honeywell’s proven RA890 series and serves as an electronic flame safeguard for burners using rectification-type flame sensing. Designed for 120 VAC operation at 50/60 Hz, it monitors flame presence and ensures that ignition occurs only under verified safe conditions. If a flame is not detected within the 15-second safety timing window during pilot trial, the unit enters lockout to prevent unsafe operation.
Key Features:
- Flame Rectification Supervision: Monitors flame presence using flame rod or rectification sensors.
- 120 VAC Operation: Powered by standard line voltage at 50/60 Hz for wide compatibility.
- Safety Lockout Timing: Initiates lockout if flame is not detected within 15 seconds of startup.
- Fast Flame Response: Reacts to flame failure within 3 seconds to shut off fuel supply quickly.
- Solid-State Circuitry: Enhances durability and reliability in demanding burner environments.
- Compatible with Q270A Sub-base: Allows easy retrofit, mounting, and serviceability.
- Lockout Indication: Supports remote alarm output for system status and diagnostics.
- Trusted Series Design: Field-proven RA890 platform for dependable burner protection.
The RA890F-1262 offers reliable burner safety control with fast response and fail-safe lockout to meet stringent combustion safety requirements.
