Honeywell R7847A1082 Amplifier
The Honeywell R7847A1082 Amplifier is a high-precision, solid-state plug-in module designed for 7800 Series Relay Modules and R7140 burner control systems. This green rectification flame amplifier identifies the presence of a flame by processing signals from gas flame rectification rods (C7004, C7005, C7007, C7008, C7009) or C7012A/C ultraviolet flame sensors. For installations where leadwire runs exceed 50 feet, the Q179 amplifier adapter is required for proper impedance matching to maintain signal integrity.
Engineering for high-demand industrial combustion, the R7847A1082 provides a selectable 2-second or 3-second flame failure response time (FFRT). Technicians can monitor performance via flame signal test jacks, which output a flame signal strength ranging from 0.0 to 5.0 Vdc. This unit serves as the direct replacement for R7847A1082/U and R7847A1108, ensuring seamless mechanical and electrical compatibility. The non-self-checking design makes it a standard choice for specific burner sequences requiring reliable, fast-acting flame detection without the complexity of dynamic self-check logic.
Key Benefits
- Compatible with Honeywell 7800 Series and R7140 primary safety controls.
- Supports rectification flame rods and specific UV sensors for versatile fuel applications.
- Features test jacks for real-time Vdc flame signal strength diagnostics.
- Selectable FFRT of 2 or 3 seconds to match specific utility or safety code requirements.
- Color-coded green casing ensures easy identification and prevents installation errors in the field.
Common Questions
Which sensors work with the R7847A1082?
This amplifier is designed for rectification type flame detectors including C7004 through C7009 gas flame rods, or C7012A and C ultraviolet flame sensors. It is not compatible with self-checking UV scanners.
What is the minimum acceptable flame signal?
For stable operation, the minimum acceptable flame signal strength is 1.25 Vdc, though a range of 2.0 to 5.0 Vdc is optimal for avoiding nuisance shutdowns.
How do I handle long leadwire runs?
When the distance between the sensor and the 7800 series relay module exceeds 50 feet, you must use a Q179 adapter to provide the necessary impedance matching.
