Manufacture: Azbil Corporation
Model: AUR355

The model AUR355 flame monitor is a combustion safety device that continuously performs self-checking of its built-in flame detection circuit to ensure safety. This device operates in combination with the model AUD300C advanced ultraviolet flame detector, the model AUD500C explosion-proof advanced ultraviolet flame detector, or a flame rod.

• Safety integrity level (SIL) 3 (pending)
• The 7-segment display shows the operating status codes, event codes, and flame voltage.
• LED indicators show whether a flame signal exists and indicate a fault stop.
• The device features host communications (RS-485) to enable remote monitoring.
