Information About RM7890A1015

The RM7890A1015 belongs to Honeywell’s 7800 Series of relay modules, providing advanced burner management with integrated diagnostics and self-checking circuitry. It performs critical control functions such as pilot ignition, main flame monitoring, and fault annunciation. The control includes five LEDs for operational sequencing and a blinking fault LED for code indication. Designed for modularity, it requires a compatible subbase, amplifier, and purge card for operation, with optional components for data communication and remote monitoring. Nonvolatile memory retains operation history and lockout status after power loss, making it ideal for high-integrity flame safeguard systems.

Key Features:

  • Integrated Microprocessor Control: Provides full automatic burner sequencing, flame supervision, and status monitoring.
  • LED Indicators: Five front LEDs display power, sequence status, and fault diagnostics through coded blink patterns.
  • Selectable Flame Establishing Periods: Configurable 4- or 10-second pilot flame establishment to match burner characteristics.
  • Interchangeable Plug-In Amplifiers: Supports a range of Honeywell flame detectors (ultraviolet, infrared, rectification).
  • Built-In Self Diagnostics: Monitors system components and generates fault codes for troubleshooting and maintenance.
  • Nonvolatile Memory: Retains operational history and lockout information even after power interruption.
  • Optional Communication Modules: Supports PC interface, Modbus communication, and remote annunciation via optional modules.
  • Selectable Relight/Lockout: Allows choice of automatic relight or lockout on flame loss for system flexibility.
  • Remote Reset & Reporting: Enables optional remote reset capability and event logging for preventive maintenance.
  • Rugged Industrial Design: Dust-cover protected housing designed for harsh burner room environments.

The RM7890A1015 delivers the reliability, control, and safety diagnostics required for modern flame safeguard systems in industrial boilers and process burners.
