APPLICATION
The RM7895A Relay Module is a microprocessor based
integrated burner control for automatically fired gas, oil or
combination fuel single burner applications. The
RM7895A consists of the Relay Module. Subbase,
Amplifier and Purge Card are required to complete the
system. Options include Keyboard Display Module (KDM),
Personal Computer Interface, Data ControlBus™* Module,
Remote Display Module, First-Out Expanded Annunciator
and Combustion System Manager™* Software.
The RM7895A is programmed to provide a level of safety,
functional capability and features beyond the capacity of
conventional controls.
Functions provided by the RM7895A include automatic
burner sequencing, flame supervision, system status
indication, system or self-diagnostics and
troubleshooting.
