Honeywell RA890F1288 Primary Control- Repaired by Acme Controls

*Electronic rectification flame detection.
*Replaces RA890E in most applications and mounts on same Q270A1024 sub-base.
*Recycles if flame signal is lost while in run. Failure to establish pilot results in a lockout.
*Safe-start check prevents start-up if flame-simulating failure occurs in flame detector circuit.
*Includes built-in protection against ignition crossover in flame rod systems.
*Includes SPDT alarm contacts.
*Solid state circuitry.
*Mounts and removes easily through use of captive mounting screws.
*Mounting base is made of strong thermoplastic.


Additional Features
  • Comprehensive Flame Detection: Utilizes a variety of detection methods, including flame rod and rectifying photocell, ensuring reliable performance across different setups. It is also compatible with the C7012A,C Ultraviolet Flame Detector for enhanced safety measures.
  • Operational Flexibility: Offers the ability to work with line or 24-volt automatic or manual controllers, making it adaptable to various system requirements.
  • Safety and Reliability: The system is designed with automatic safety shutdown protocols, engaging if the flame fails to start or is not re-established after failure. This ensures protection and minimizes risk in case of operational discrepancies.
  • Ease of Maintenance: The solid-state circuitry not only eliminates the need for vacuum tube replacements but also provides increased resistance to vibration, enhancing the durability and longevity of the unit. Additionally, there’s no need for power application during the Off cycle, saving energy and reducing operational costs.
  • User-Friendly Design: Features a push-to-reset safety switch housed in a dust-resistant enclosure, ensuring easy operation and maintenance. Captive mounting screws facilitate straightforward installation and removal.

These features collectively make the Honeywell RA890F1288 Primary Control a robust and versatile solution for flame safeguard applications, providing safety, reliability, and ease of use.

Understanding the Honeywell RA890F Flame Safeguard Relay

The RA890F Flame Safeguard Relay is a critical component in industrial and commercial burner systems. It's specifically designed to ensure the safe operation of gas, oil, or combination gas-oil burners.

Key Functions:
  • Flame Detection: The relay monitors the presence of a flame, ensuring it is burning properly. If the flame goes out unexpectedly, the relay can trigger safety mechanisms to prevent hazards.
  • Solid State Electronics: This relay uses advanced electronics to provide reliable performance and minimize mechanical wear, leading to longer-lasting operation.
  • Safety Assurance: Its primary role is to enhance safety by preventing unsafe burner conditions through timely response to flame status, which protects the equipment and minimizes risk.
  • This relay is ideal for systems requiring consistent and automated flame monitoring to ensure they operate safely and efficiently.

    The Honeywell RA890F 120V Protectorelay provides flame safeguard protection for single or dual burners. The RA890F line of primary controls is a non-programming, rectification flame amplifying relay providing solid state safeguard protection for industrial and commercial gas, oil, or combination burners.

    To measure the flame signal current in the Honeywell RA890F, you can directly access the test jack provided on the device. This feature allows for a straightforward and efficient method to check the flame signal by connecting a suitable meter. Ensure your meter is set to the correct range to accurately assess the current. This direct measurement capability helps in diagnosing and troubleshooting any flame detection issues effectively.


    Other popular models include RA890F1247, RA890F1254, RA890F1262, RA890F1270, and RA890F1338. We rebuild ALL RA890F models and have many of the very common ones on our shelf available to ship same day.
