It works with C7027, C7035, or C7044 Minipeeper Ultraviolet Flame Detectors and supports both line voltage and low-voltage controllers. Designed for use in environments that demand fast flame failure detection, this unit ensures burner safety through its automatic lockout functionality and a flame establishment period of up to 15 seconds. Key Features: Fast Flame Failure Response: 0.8-second response time with 15-second safety switch lockout. Universal Flame Detector Support: Compatible with C7027, C7035, or C7044 UV flame detectors. Interrupt or Intermittent Ignition: Works with both oil and gas burners in safety-critical applications. Safe-Start Logic: Prevents burner start if flame or flame simulation fault is present. Push-to-Reset Safety Lockout: Dust-resistant enclosure with manual reset for fault clearing. Automatic Shutoff on Flame Loss: Securely de-energizes fuel valves if flame fails post-ignition. LED/Signal Testing: Built-in test jack allows flame signal measurements during service. Extreme Temperature Ready: Operates from -20°F standard, optional model available for -40°F. Easy Mounting: Captive screws and thermoplastic base simplify installation and removal. Solid-State Reliability: Withstands vibration and eliminates warm-up delay using advanced circuitry. The RA890G1229 offers rapid flame detection, automatic safety lockout, and compatibility with UV flame sensors—making it ideal for demanding burner applications requiring fast response and high reliability.
