D-UG 660
Control unit
Control unit for high requirements, for combination with optical flame sensors. For monitoring gas, oil and coal flames, including in complex multi-burner plants.
Functionality: Optical flame monitoring
Features
- Different presettings for FFDT and flame intensity switching threshold
- Consistent two-channel design for maximum safety combined with high availability
- Two flame ON/OFF contacts for the flame signal (normally open and normally closed)
- Connection of all DURAG GROUP optical flame sensors possible
- Two analogue outputs 0/4 … 20 mA
Benefits
- Same device can be used for different combustion situations
- Quick changeover if operation of the combustion plant changes
Applications
- Complex combustion plants including plants with many burners and different fuels
- Combustion processes in continuous operation
