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.
