R7824, R7847, R7848, R7849,
R7851, R7861, R7886 Amplifiers for
7800 SERIES Relay Modules
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 an 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 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.
he R7861A Self-Check Ultraviolet Flame Amplifier is a solid
state plug-in amplifier that responds to an ultraviolet signal
from a C7061A Self-Check Ultraviolet Flame Detector to
indicate the presence of flame when used with 7800 SERIES
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 Relay Modules.
FEATURES
• Flame failure response time (FFRT) 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
(see Table 2):
— 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.
