Product Description

The ABB FAU810 is a high-precision Flame Analysis Unit engineered to monitor and analyze flame conditions in industrial combustion systems. It interprets optical signals from ABB flame detectors, such as the SF810 series, ensuring safe and efficient operation in boilers, furnaces, and multi-burner installations.

Designed for integration into ABB AC800M platforms, the FAU810 provides real-time flame status to control systems, distinguishing between valid flame signals and background noise or spurious radiation. Its intelligent processing minimizes false trips and ensures continuous plant operation.
