Information About 190971B
The 190971B shutter assembly is a key component used in Honeywell’s C7012E, C7012F, and similar self-checking ultraviolet flame detectors. Its function is to periodically interrupt the UV sensor’s view of the flame, allowing the Flame Safeguard amplifier to confirm the detector’s proper operation. Powered by 120 VAC at 50/60 Hz, the assembly includes both the electromagnetic coil and the mechanical shutter mechanism in one integrated module. This component is typically mounted inside the flame detector housing and operates automatically as part of the self-check circuit cycle. The 190971B was supplied as an OEM replacement part and is now discontinued by the manufacturer, though it remains critical for maintaining reliability in legacy Honeywell flame monitoring systems.
Key Features:
- Replacement Self-Check Shutter Assembly: Restores full self-checking functionality to compatible Honeywell UV flame detectors.
- Integrated Coil and Shutter Mechanism: Provides synchronized electrical and mechanical motion for self-test cycling.
- 120 VAC Power Operation: Designed for detectors operating on standard 120 V supply at 50/60 Hz.
- Durable Construction: Built for continuous use in industrial burner environments.
- Direct Fit Compatibility: Installs directly into C7012E and C7012F self-checking detectors without modification.
- Factory-Calibrated Movement: Ensures accurate shutter timing to maintain flame verification integrity.
- Easy Replacement: Designed for quick field servicing with standard tools.
- Reliable Operation: Maintains compliance with Honeywell Flame Safeguard system requirements.
- Extended Service Life: Precision-built coil and shutter for long-term durability under high operating temperatures.
The 190971B ensures accurate and safe flame verification, maintaining dependable performance in Honeywell self-checking flame detection systems.
