R7847A1033 Honeywell Flame Amplifier
$260.00
The Honeywell R7847A1033 is a rectification flame amplifier for use with Honeywell 7800 Series relay modules. It offers a selectable flame failure response time (FFRT) of 2.0 or 3.0 seconds, reads flame signal levels from 0.0 to 5.0 Vdc, and is compatible with rectifying flame rods and ultraviolet sensors. Built for reliable flame detection in gas, oil, or coal burner systems.

The Honeywell R7847A1033 STANDARD. 3S FFRT. RECOMMENDED FOR CYCLED HEATING EQUIPMENT. USE WITH Flame ROD, PHOTO- CELL, OR C7012A,C.
Overview
Solid-state plug-in flame amplifier designed to process flame detector inputs and indicate flame presence when used with the Honeywell 7800 Series primary safety control relay modules. Ideal for burner systems needing durable, reliable flame monitoring with moderate response times.
Key Features
Flame Failure Response Time (FFRT): Selectable at 2.0 seconds or 3.0 seconds for different startup requirements or safety margins.
Flame Signal Range: 0.0 Vdc to 5.0 Vdc signal reading via test jacks, allowing measurement of signal strength.
Detection Type Compatibility:
• Rectifying flame rods (gas sensors): C7004, C7005, C7007, C7008, C7009, Q179
• Ultraviolet flame sensors for gas, oil, coal: e.g., C7012A/CConnector & Installation: Plug-in design using printed circuit board (PCB) edge connector, keyed for proper orientation into 7800 Series relay modules.
Color Coding: Green label to denote rectification type amplifier, for quick visual identification
Environmental & Operating Conditions:
• Operating temperature: −40°F to +140°F (−40°C to +60°C)
• Storage: −40°F to 150°F (−40°C to +65°C)
• Humidity: continuous up to ~85% RH, non-condensingSafety & Control: Used with primary safety control via 7800 Series relay modules. When system fails or flame detection fails, relay module performs lock-out for safety.
