D-UG 660 Control unit

D-UG 660 Control unit

D-UG 660 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.

The D-UG 660 control unit 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.
