PRODUCT DATA
APPLICATION
The R7824C Rectification Flame Amplifier is a solid state
plug-in amplifier that responds to a rectified signal from a
C7024E,F Self-Check Ultraviolet Flame Detector to indicate
the presence of flame when used with the 24 Vdc RM7824
Relay Module.
The R7847A,B Rectification Flame Amplifiers are solid state
plug-in amplifiers that respond to a rectified signal from a
rectification type flame detector to indicate the presence of
flame when used with 7800 SERIES and R7140 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
and R7140 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 plugin amplifiers that respond to an infrared signal from a C7015
Infrared Flame Detector to indicate the presence of flame
when used with 7800 SERIES and R7140 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 and
R7140 Relay Modules.
The R7851B Optical Flame Amplifiers are solid state plug-in
amplifiers that respond to optical signals from C7927 and C7962
Flame Detectors to indicate the presence of flame when used
with 7800 SERIES and R7140 Relay Modules.
The R7852A,B Infrared Flame Amplifiers are solid state plugin amplifiers that respond to an infrared signal from a C7915
Infrared Flame Detector to indicate the presence of flame
when used with 7800 SERIES and R7140 Relay Modules.
The R7851C Dynamic Self-Check Optical Flame Amplifier is a
solid state plug-in amplifier that responds to ultraviolet signals
from C7961E Dynamic Shutter-Check ultraviolet flame
detectors to indicate the presence of flame when used with
7800 SERIES and R7140 Relay Modules.
The R7861A Self-Check Ultraviolet Flame Amplifier is a solid
state plug-in amplifier that responds to an ultraviolet signal
from a C7061 Self-Check Ultraviolet Flame Detector to
indicate the presence of flame when used with 7800 SERIES
and R7140 Relay Modules.
The R7886A Dynamic Self-Check Ultraviolet Amplifier is a
solid state plug-in amplifier that responds to a pulsed direct
current signal from a C7076A,C Ultraviolet Flame Detector
with adjustable sensitivity to indicate the presence of flame
when used with 7800 SERIES and R7140 Relay Modules.

R7824, R7847, R7848, R7849, R7851, R7852, R7861, R7886 AMPLIFIERS FOR 7800 SERIES AND R7140 RELAY MODULES
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 and R7140 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 and R7140 Relay Module
locks out on safety shutdown with amplifier failure.
• R7824C 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 and R7140 Relay Module locks out on safety
shutdown with flame detection system failure.
