Information About RM7890B1030
The RM7890B1030 is part of Honeywell’s 7800 Series relay module family for single-burner applications. It uses interchangeable plug-in flame amplifiers and requires a compatible Q7800 subbase and flame amplifier for operation. The control supports intermittent pilot operation, a fixed 4- or 10-second pilot flame establishing period, and an intermittent main flame establishing period. Its integrated diagnostics, non-volatile memory, LED sequence indication, and optional communication interfaces support burner system monitoring and troubleshooting.
Key Features:
- Primary Burner Control: Provides on-off control for automatically fired gas, oil, or combination fuel burners.
- 120 VAC Operation: Designed for 120 VAC power at 50/60 Hz.
- Intermittent Pilot: Supports intermittent pilot ignition with a fixed 4- or 10-second pilot flame establishing period.
- Burner Sequencing: Controls automatic burner operating sequences and flame supervision.
- Flame Monitoring: Supports selectable relight or lockout operation following loss of flame.
- Diagnostics: Provides system and self-diagnostic functions with five LEDs for sequence indication.
- Non-Volatile Memory: Retains historical files and lockout status after power loss.
- Optional Interfaces: Supports keyboard display, remote display, Modbus communication, and local or remote annunciation options.
The RM7890B1030 delivers the reliability and precision required for automatic burner sequencing and flame supervision applications.
