Information About RM7840G1022
The RM7840G1022 integrates burner sequencing and flame safeguard functions into a single control module for industrial and commercial combustion systems. It supports 10-, 15-, or 30-second or intermittent main flame establishing periods and 4- or 10-second pilot flame establishing periods. The control includes a selectable second-stage pilot valve, 5-second early spark termination, and user-selectable airflow checking for configurable burner sequences. Pre-purge timing is determined by the ST7800A pre-purge timer card, while post-purge can be programmed through the S7800A1142 display.
Key Features:
- Microprocessor-Based Control: Provides integrated burner sequencing and flame safeguard functions for automatically fired single-burner applications.
- Valve Proving: Incorporates valve proving functionality with LHL-LF proven purge operation.
- Flexible Flame Timing: Supports 10-, 15-, and 30-second or intermittent main flame establishing periods.
- Selectable Pilot Period: Provides 4- or 10-second pilot flame establishing periods.
- Interrupted Pilot: Uses an interrupted pilot sequence for burner ignition control.
- Second-Stage Pilot Valve: Allows selection of a second-stage pilot valve configuration.
- Early Spark Termination: Provides a 5-second early spark termination period.
- Burner Interlocks: Includes running interlocks and a user-selectable airflow check.
The RM7840G1022 delivers configurable burner sequencing, valve proving, and flame-safety control for demanding combustion applications.
