Manufacture: Azbil Corporation
Model: AUR255

The model AUR255 burner controller ensures combustion safety. It specifically targets batch operations. These systems start and stop at least once every 24 hours. The controller safely and automatically ignites gas and oil burners using the proper ignition sequence. You must pair this device with an AUD100/110/120 advanced ultraviolet flame detector or a flame rod.

• The design complies with JIS C 9730-2-5 and JIS C 9730-1.
• A built-in trial logger records input/output and flame voltage.
• It captures this data at 100 ms intervals for a set period after ignition begins.
• The system provides burner health indexes, like ignition time, to help you monitor burner status.

Summary

The burner controller ensures combustion safety during batch operations. These systems start and stop at least once every 24 hours.

• The front panel features a 7-segment LED display.
• This screen shows the flame voltage and the current sequence stage.
• Users can easily access communication and event functions from the front panel.
• These functions make maintenance and troubleshooting highly convenient.
• The 7-segment display shows the normal operating sequence and flame voltage.
• During an alarm, the display alternately flashes the sequence code and alarm code.
• This feature allows users to view alarm details easily.
• The communication function reads out basic data like input/output status.
• It also provides the operating history and alarm history.
• Accessing this internal information aids in troubleshooting and preventive maintenance.
• LED indicators show the presence of a flame signal and indicate lockout states.
• The system performs self-diagnosis on the internal control relay circuit.
• The controller requires a manual reset if a lockout occurs from an ignition or flame failure.
• The design fully complies with JIS C 9730-2-5 and JIS C 9730-1.
• Host communications (RS-485) enable remote monitoring.
• The device features DIN rail mounting and a sub-base structure for easy installation and replacement.
• A trial logger records input/output and flame voltage at 100 ms intervals.
• It logs this data for a fixed duration immediately after ignition begins.
• The device outputs the flame level, a more responsive index than flame voltage.
• The controller also provides burner health indexes, such as ignition time.
