Honeywell EC / RM 7823

The Honeywell EC7823 (230VAC) or RM7823 (120VAC) relay module is a microprocessor-based flame detection relay that can be mounted with any Honeywell 7800 series amplifier. Base and amplifier are required to complete the system and are selected according to the desired process conditions. The optional display can be mounted on the relay module or on the front of a panel door. The display can also be mounted remotely from the panel if approved for the application. Basic functions of the EC / RM 7823 include flame monitoring, system status indication, system or self-diagnosis and troubleshooting.

Note: The EC7823/RM7823 is a flame detection relay only. A switchable primary control must be used to provide safe start control, safety interlock, load switching and other functions required in flame protection systems (as described in standard EN 746-2).

Features and Benefits:
  • Interchangeable plug-in flame amplifiers i.f. desired process parameters (e.g. reaction time in case of flame failure)
  • Preservation of history files after power failure
  • Remote reset (optional)
  • Display module remotely mountable
  • Following burner control data available on (optional) display module:
    • Flame signal strength
    • Total number of duty cycles
    • Total operating hours
    • Failure history with the six most recent failures
    • Diagnostic information (flame amplifier type, flame failure response time, production code and software revision)
