Information About RM7890C1005
The RM7890C1005 is a Honeywell 7800 Series relay module designed for on-off control in semi-automatic industrial burner systems. It is suitable for single burners using gas, oil, coal, or combination fuels and provides advanced diagnostics, lockout memory, and operational feedback via onboard LEDs. The unit requires a compatible subbase and flame amplifier for full operation, and it can be enhanced with optional accessories such as PC interfaces, remote displays, and first-out annunciators. Though discontinued by the manufacturer, the RM7890C1005 remains widely used in legacy combustion safety systems.
Key Features:
- Burner Sequencing Control: Automates startup, operation, and shutdown processes.
- Advanced Diagnostics: LED indicators and lockout fault codes assist in troubleshooting.
- Modular Design: Compatible with plug-in flame amplifiers and optional accessories.
- Memory Retention: Nonvolatile memory stores fault history and sequence data through power loss.
- Annunciation Options: Supports local or remote fault annunciation and reset capabilities.
- Multiple Interfaces: Expandable with PC tools and data modules for system management.
- 120 VAC Power Input: Designed for standard industrial power systems.
- Discontinued Model: No longer in production, but still supported in many field applications.
The RM7890C1005 delivers reliable primary control and diagnostic functions for industrial burner systems.
