7800 SERIES Relay Modules

APPLICATION

The Honeywell EC/RM7823A Relay Module is a 

microprocessor based flame detector relay that can be fitted 

with any 7800 SERIES Flame Amplifier to provide relay action 

from one dpdt relay when flame is or is not present. The 

EC/RM7823A system consists of a relay module, wiring 

subbase and flame amplifier. Options include keyboard 

display module (KDM), personal computer interface, Data 

ControlBus Module™, remote display mounting and 

Combustion System Manager™ Software. 

Functions provided by the EC/RM7823A include flame 

monitoring, self-diagnostics and troubleshooting.The 

EC/RM7823A is a solid state replacement for the R7023B,C 

Flame Detector Relays.

The EC7823/RM7823 is a flame detector relay only. A 

switchable primary control must be used to provide safe-start 

check, safety lockout, load switching and other functions 

required in Flame Safeguard systems.
