- Model AUR890
Burner Controller model AUR890 were developed as an upgrade for the model RA890 ProtectoRelay, and are designed for batch operation of combustion equipment (at least one start and stop in a 24-hour period). This device is used in combination with model AUD100 /110/120 Advanced Ultraviolet Flame Detector or a flame rod. For combustion equipment that operates continually for 24 hours or longer, use a burner controller designed for continuous operation instead of this device. This device is structured for external instrumentation of the prepurge function. It automatically ignites the pilot and main burners and monitors the flame. In addition, when flame failure occurs, this device locks out the combustion equipment.
