Honeywell R7847A1074 Amplifier
The Honeywell R7847A1074 Amplifier is a solid-state, plug-in component specifically designed for use with 7800 Series Relay Modules and R7140 Series primary safety controls. This rectification flame amplifier offers a selectable flame failure response time (FFRT) of either 0.8 or 1.0 seconds, providing high-speed detection and safety shutdown capabilities for industrial and commercial burner applications. Designed for maximum compatibility, it supports rectifying flame rods (models C7004, C7005, C7007, C7008, C7009) and can be used with a Q179 for impedance matching on lead wire runs exceeding 50 feet. It is also compatible with ultraviolet flame sensors (C7012A and C).
Encased in a green-coded housing for easy identification of the rectification type, the R7847A1074 provides a reliable 0.0 to 5.0 Vdc flame signal strength measurement via on-board test jacks. This allows technicians to perform accurate flame signal monitoring and troubleshooting without interrupting burner operation. This unit is the direct replacement for R7847A1074/U and R7847A1090 models, ensuring a seamless fit into existing Honeywell flame safeguard systems. Its keyed edge connector ensures correct orientation during installation, reducing the risk of equipment damage during field service.
Key Benefits- Field-Selectable FFRT: Choose between 0.8 and 1.0 second response times to meet specific safety requirements for various burner configurations.
- Enhanced Monitoring: Integrated test jacks provide precise DC voltage readings for real-time signal strength verification.
- Direct Retrofit: This flame signal amplifier serves as a direct drop-in replacement for legacy R7847A1090 and R7847A1074/U units.
- Broad Sensor Compatibility: Seamlessly integrates with standard rectifying rods and specific UV sensors, allowing for flexible fuel applications.
- Rugged Solid-State Design: Built to withstand commercial boiler room environments while maintaining signal accuracy and response consistency.
What does the green color coding signify on this amplifier?
The green label identifies this as a rectification type amplifier, preventing accidental installation of incompatible infrared or ultraviolet-only amplifiers into the 7800 series module.
Can I use this amplifier for lead wire runs longer than 50 feet?
Yes, when using rectifying flame rods with lead wires over 50 feet, a Q179 connector is required for proper impedance matching to maintain signal integrity.
Is this model a self-check amplifier?
No, the R7847A1074 is a non-self-checking amplifier. Systems requiring dynamic self-checking must utilize a different R7847 series model and compatible sensors.
