        More Information

        Overview Manuals Flame Supervision Safety Timing Electrical Input Alarm Circuit

        Features:

        • The 220 V control supervises burner flame on 50 or 60 Hz panel circuits.
        • A 15-second safety-switch interval and 0.8-second flame-failure response handle separate safety events.
        • SPDT alarm contacts provide a changeover path for external burner-status indication.
        The RA890F architecture is panel wired, so supply, detector, interlock, and alarm circuits meet at defined control terminals.

        Flame sensing may use rectification, photocell, or approved ultraviolet detection according to the burner arrangement.

        Exact suffix matching prevents a unit with different voltage, timing, or contact behavior from being treated as the same control.

        The Honeywell RA890F 1304 RA890F Flame Safeguard Primary Control may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Honeywell RA890F 1304 Flame Safeguard Primary Control Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Burner-Flame Monitoring Path

        • Control task: The primary control supervises the selected flame detector during the burner operating sequence.
        • Detector methods: RA890F equipment can receive rectification, photocell, or ultraviolet flame-sensing signals.
        • Fuel scope: The family is applied to gas, oil, and combination gas-oil burner systems.
        • Wiring form: Panel wiring carries detector and control signals through point-to-point field circuits.

        Startup and Flame-Loss Intervals

        • Safety interval: The 1304 configuration uses a 15-second safety-switch timing.
        • Loss response: An established flame failure is acted on within the documented 0.8-second response.
        • Separate functions: Startup safety timing and flame-failure response are different control intervals.
        • Suffix importance: Other RA890F suffixes can have different timing values, so the 1304 identity remains essential.

        Supply Configuration

        • Nominal supply: The exact 1304 control is listed for 220 V AC.
        • Frequency: Its supply-frequency range covers both 50 and 60 Hz.
        • Panel circuit: Supply and burner interlock wiring are connected through the installed control panel.
        • Pre-service check: Voltage and frequency are verified at the installed control before an exchange is planned.

        External Status Contact

        • Contact form: The documented alarm output uses a single-pole double-throw changeover arrangement.
        • Circuit choice: The external alarm circuit selects the required normally open or normally closed path.
        • Status use: The contact can pass the control state to an annunciation or supervisory circuit.
        • Wiring record: Existing terminal and interlock assignments are recorded before the control is disconnected.
        Description
        Honeywell RA890F 1304 is an RA890F flame safeguard primary control used to supervise burner flame and move the control circuit toward shutdown when an unsafe flame-loss condition is detected. The exact 1304 suffix identifies its electrical and timing arrangement.

        The input configuration of RA890F 1304 is 220 V AC at 50 or 60 Hz. Its 15-second safety-switch timing belongs to the startup safety sequence, while the 0.8-second flame-failure response governs the faster reaction after an established flame is lost.

        Alarm signaling on RA890F 1304 uses SPDT contacts, giving the external circuit a changeover contact arrangement. The RA890F family supports flame supervision for gas, oil, or combination gas-oil burners through the documented detector methods.

        As a panel-wired point-to-point control, RA890F 1304 is matched by its voltage, frequency, timings, alarm-contact form, and connected flame-sensing circuit. Those attributes are checked together before service work because another RA890F suffix can carry different timing or contact behavior.

        Technical notes
        Honeywell RA890F 1304 operates at 220 V and 50/60 Hz with a 15-second safety-switch interval, 0.8-second flame-failure response, and SPDT alarm contacts.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Which configuration points must match before Honeywell RA890F 1304 replaces another RA890F control?
        Honeywell RA890F 1304 must match 220 V, 50/60 Hz, 15-second safety timing, 0.8-second response, and SPDT alarm contacts.
        How are the 15-second and 0.8-second timings used differently by RA890F 1304?
        On RA890F 1304, 15 seconds belongs to the safety-switch sequence, while 0.8 second is the flame-failure response.
        What should be verified in the panel supply before connecting Honeywell RA890F 1304?
        The panel circuit for Honeywell RA890F 1304 must provide the documented 220 V AC supply at 50 or 60 Hz.
        How does the SPDT alarm output of RA890F 1304 affect external status wiring?
        RA890F 1304 provides a changeover contact, allowing the external circuit to use the required normally open or normally closed path.
        Why is an RA890F family-name match alone insufficient for selecting Honeywell RA890F 1304?
        Different suffixes can carry different electrical, timing, and contact arrangements, so Honeywell RA890F 1304 requires the exact 1304 identity.
        What happens after an established burner flame is lost while RA890F 1304 is supervising it?
        RA890F 1304 detects the flame-loss condition with its documented 0.8-second response and initiates the configured safety action.
