Honeywell EC7890B1010 burner control module:
The Honeywell EC7890A,B/RM7890 is a microprocessor based integrated burner control for automatically fired gas, oil or combination fuel single burner applications. The EC/RM7890 system consists of the Relay Module, Subbase and Amplifier. Options include Keyboard Display Module (KDM), Modbus module, Data ControlBus Module, and Remote Display Module. The EC/RM7890 is programmed to provide a level of safety, functional capability and features beyond the capacity of conventional controls. Functions provided by the EC/RM7890 include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and troubleshooting.

Features:
-Preignition Interlock Input
-Selectable Intermittent/Interrupted Pilot Function (full pilot flame and main flame establishing periods apply if interrupted pilot feature selected)
-Run/Test Switch for interrupted pilot setup.
-Blinkum fault annunciation on safety shutdown (power LED blinks a fault code)
-Built-in features set up only using the S7800A1142 display.
-Valve Proving System.
-The Valve Proving System feature provides a systematic way of testing the valve seat integrity to assure the valves are indeed in the closed state programmed to test at the time of startup, at the end of the call for heat, or both times

Safety features:
-Closed loop logic test.
-Dynamic AMPLI-CHECK.
-Dynamic input check.
-Dynamic safety relay test.
-Dynamic self-check logic.
-Expanded safe-start check.
-Internal hardware status monitoring.
-Tamper resistant timing and logic.
-Access for external electrical voltage checks.
-Application flexibility.
-Communication interface capability using modbus.
-Dependable, long-term operation provided by microcomputer technology.
-First-out annunciation and system diagnostics are provided by a 2 row by 20 column Vacuum Fluorescent
-Display (VFD) located on the optional Keyboard Display Module.
-Five (LEDs) for sequence information. (See Fig. 1.)
-Interchangeable plug-in flame amplifiers.
-Local or remote annunciation of RM7890 operation and fault information using the optional Keyboard Display Module.
-Non-volatile memory; EC/RM7890 retains history files and sequencing status after loss of power.
-Provides 0.8 or 3.0 second FFRT, depending on amplifier selected. EC7890A1029, EC7890B1028 are 1.0 or 2.0 second FFRT.
-Remote reset (optional)
-Selectable relight (0.8 second FFRT amplifier only) or lockout on loss of flame.
-Shutter drive output (EC/RM7890B).
-Burner controller data (optional):
-Flame signal strength.
-Hold status.
-Lockout/alarm status.
-Sequence status.
-Sequence time.
-Total cycles of operation.
-Total hours of operation.
-Fault history providing the six most recent faults
