Honeywell 7800 series burner control units and flame detection relays are microprocessor-based industrial burner controls for automatic (gas or oil) fired burner applications. The 7800 series is suitable for all types of burners with unlimited capacity and can be further extended for remote monitoring via Honeywell Thermal IQ technology.

Features and Benefits:

• Quick-mount wiring base for all 7800 SERIE relay modules allow wiring of the control system prior to relay module installation.
• Modular design with plug-in modules (flame detection depending on the type of plug-in flame amplifier)
• Adjustable purge time via plug-in purge card (ST7800A1xxx/U)
• Failure response time:
  • European controllers (EU): 1.0 or 2.0s (depending on the type of flame amplifier
  • American controllers (US): 0.8 or 3.0s (depending on the type of flame amplifier)
• Optional display can be mounted on the module or on a panel door

• EU models are CE-approved according to EN 298 for continuous operation (when used with the correct flame amplifier and flame sensor!)
• SIL-3 certified (all models except EC/RM7823 flame switches)
• Protection class:
  • Europe: IP00 (cabinet mounting only)
  • USA: NEMA 1 (cabinet or wall-mounted)
• Ambient temperature: -40°C to 60°C
• Accepts all existing optical flame detectors (UV) and ionization electrodes (flame rods) from Honeywell
