The R7847A,B Rectification Flame Amplifiers are solid state plugin amplifiers that respond to a rectified signal from a rectification type flame detector to indicate the presence of flame when used with 7800 SERIES Relay Modules.
The R7847C Self-Check Rectification Flame Amplifier is a solid state plug-in amplifier that responds to a rectified signal from a C7012E,F Self-Check Ultraviolet Flame Detector to indicate the presence of flame when used with 7800 SERIES Relay Modules. This is not European Community (CE) approved for EC7810, EC7820, EC/RM7830 or EC/RM7850 Relay Modules. The R7848A,B Infrared Flame Amplifiers are solid state plug-in amplifiers that respond to an infrared signal from a C7015 Infrared Flame Detector to indicate the presence of flame when used with 7800 SERIES Relay Modules.
The R7849A,B Ultraviolet Flame Amplifiers are solid state plug-in amplifiers that respond to an ultraviolet signal from a C7027, C7035 or C7044 Ultraviolet Flame Detector to indicate the presence of flame when used with 7800 SERIES Relay Modules. The R7851B Optical Flame Amplifiers are solid state plug-in amplifiers that respond to optical signals from C7927, C7935, C7915, and C7962 Flame Detectors to indicate the presence of flame when used with 7800 SERIES Relay Modules.
Honeywell R7824, R7847, R7848, R7849,R7851,R7861, R7886 FEATURES
- Flame failure response time of 0.8 or 1 second; or 2.0 or 3.0 seconds, depending on the amplifier and relay module selected. See Table 1.
- Plug-in to 7800 SERIES Relay Module through printed circuit board edge connector keyed for proper orientation.
- Flame signal test jacks measure amplifier flame signal voltage.
- 0.0 to 5.0 Vdc Flame signal strength reading range.
- Color coded label identifies flame detection type:
- Green - rectification. Red - infrared.
- Purple - ultraviolet. Blue - pulsed rectification.
- White - optical.
- R7847B, R7848B, R7849B Dynamic Ampli-Check® circuitry tests all flame amplifier components 12 times per minute. The 7800 SERIES Relay Module locks out on safety shutdown with amplifier failure.
- R7824C and R7847C Dynamic Self-Check Rectification Amplifier, R7851C Dynamic Self-Check Optical Flame Amplifier, R7861 Self-Check Ultraviolet Flame Amplifier and R7886A Dynamic Self-Check Ultraviolet Amplifier test the detectors and all electronic components in the flame detection system 12 times per minute. The 7800 SERIES Relay Module locks out on safety shutdown with flame detection system failure.
NOTE: NOTE:R7824C, Series 2 or greater, and R7847C, Series 4 or greater, pulse shutter when signal of 1.5 Vac is sensed.
