D-GF 75 | ASD-75
Burner controls

Self-monitoring and fail-safe burner controls for controlling simple gas burners with electric ignition.

Functionality: Safety-related control

  • Compact design
  • Control and monitoring of gas and oil burners as well as gas and oil pilot burners of any capacity
  • Pre-purge of boiler with adjustable pre-purge time and optional air pressure check
  • Adjustable safety times
  • Input for external flame monitor
  • Optional re-cycling after flame failure in operating position
  • Integrated ionization flame monitor (D-GF 75)
  • Input for a flame signal with 90 … 110 VDC (ASD-75)
  • Change of process parameters without device exchange
  • Assumption of standard-compliant safety-related switching of simple burners
  • Use of external flame monitors already in place possible
  • Frequent switching of simple burners, for example in heat treatment
  • Process heaters
  • Control of gas ignition burners
  • Technical data
Operating modeIntermittent operation and continuous operation (different variants)
