Durag D-UG 660 is self-monitoring and fail-safe control unit for monitoring gas, oil and coal flames with DURAG UV, UV+IR or IR-flame sensors, primarily in multi-burner view applications. It analyses the flame radiation via the pulse signal of the flame sensor connected. The easy-to-read LCD display continually shows information on the defined setting and operational status. The flame intensity and signal are present at two current outputs 0/4 ... 20 mA for further analysis. It mainly come with typical features as below:
u Suitable for intermittent operation as well as continuous operation
u Optional parallel operation of two flame sensors in any combination: UV/UV, UV/IR or IR/IR.
