        Features:

        • Analyzes two independent flame-scanner channels for industrial burner supervision.
        • Evaluates intensity, frequency, quality, or AC amplitude and supplies two assignable analog outputs.
        • Performs an electronic self-check every 0.1 s and provides three Form C relay outputs.
        The current product is FAU810, the ABB Uvisor Flame Analysis Unit 810 for utility and industrial combustion systems.

        It processes flame-detector signals, trends flame quality, and communicates diagnostic and configuration data through redundant serial interfaces.

        Before commissioning, confirm detector type, channel limits, relay logic, analog-output mapping, serial protocol, supply voltage, and flame-failure timing.

        Availability is subject to Apter Power inventory and sourcing confirmation.

        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.

        • Supervises burner flames in utility boilers, industrial furnaces, kilns, and other combustion equipment.
        • Supports flame analysis for natural gas, heavy oil, coal, lignite, biomass, and other compatible fuel applications.
        • Provides a modernization platform for established ABB flame-scanner installations when detector and wiring compatibility are verified.
        • Provides two galvanically isolated RS-485 interfaces that are fully independent for redundant communication.
        • Uses Modbus as the default serial format and supports selectable PROFIBUS DP-V1 integration.
        • Allows each RS-485 interface to access both flame-analysis channels for data exchange and tuning.
        • Sets the flame-failure relay dropout from 0.2 to 2.5 seconds for the approved burner-protection strategy.
        • Assigns each 4–20 mA output independently to intensity, frequency, quality, or AC amplitude.
        • Supports authorized remote setup and interrogation through the RS-485 link and Flame Explorer software.
        • Checks the electronics every 0.1 seconds to detect faults that could create an unsafe condition.
        • Consumes 4 W minimum, 6 W typical, and 10 W maximum from the 24 VDC supply.
        • Provides three Form C relay outputs for Flame 1, Flame 2, and either Flame 3 or fault duty.
        Description
        FAU810 is the ABB Uvisor Flame Analysis Unit 810, designed to interrogate and analyze two flame-scanner signals in utility and industrial combustion systems.

        It evaluates intensity, frequency, quality, or AC amplitude, provides three Form C relays and two assignable 4–20 mA outputs, and exchanges real-time data through two galvanically isolated RS-485 interfaces using Modbus or selectable PROFIBUS DP-V1.

        Continuous self-checking can drive a flame-out indication when an unsafe fault is detected. Verify detector compatibility, 24 VDC supply, relay loading, communication selection, flame limits, and dropout timing before commissioning.

        Technical notes
        For FAU810, verify each detector type, channel setup, and flame-failure relay timing before commissioning; these settings directly affect loss-of-flame signaling.

        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 combustion applications can use FAU810?
        ABB positions FAU810 for burner flame analysis in utility and industrial boilers using compatible ABB flame-sensing devices.
        Can FAU810 evaluate more than raw flame intensity?
        Yes. Its monitoring can use intensity, frequency, flame quality, or AC amplitude according to the configured channel function.
        How does FAU810 respond to an unsafe internal or detector fault?
        Continuous diagnostics can indicate flame-out to the boiler protection system so the predetermined loss-of-flame action can occur.
        Can FAU810 settings be adjusted remotely?
        Authorized personnel can use Flame Explorer over RS-485 to configure limits, dropout and pull-in behavior, and discrimination parameters.
        What should be preserved when replacing an FAU810 in an existing boiler?
        Preserve detector assignments, channel limits, relay logic, analog-output mapping, serial protocol, network address, and flame-failure timing.
        What information should be included in an FAU810 quotation request?
        Provide the FAU810 model, detector types, required protocol, quantity, destination, and documentation needs.
