Honeywell R7847A1082/U

Regular price $624.00

Solid state plug-in amplifiers that respond to flame detector inputs to indicate the presence of flame when used with 7800 SERIES relay modules.


  • Flame failure response time of 0.8 or 3.0 seconds.
  • Flame signal strength ranges from 0.0 to 5.0 Vdc.
  • Plug into 7800 relay module through printed circuit board edge connector keyed for proper orientation.
  • Flame signal test jacks to measure amplifier flame signal voltage.
  • Color-coded labels identify flame detection type. Dynamic Self-Check Amplifier test the detectors and all electronic components in the flame detection system 7800 SERIES relay module locks out on safety shutdown with flame detection system failure.
  • Compatible with existing Honeywell flame detectors (order separately).
  • Type: Rectification
  • Flame Failure Response Time (sec): 2.0 sec or 3.0 sec
  • Self Checking: None (standard)
  • Use With Primary Safety Control: 7800 SERIES Relay Modules
  • Use With Flame Sensor: Gas: Rectifying Flame Rods C7004,5,7,8, or 9, Q179 for impedance matching for leadwire runs > 50' or Ultraviolet Flame Sensor C7012A, C
