DC300K-E-0A3-21-0000-0 HONEYWELL

Product Dimensions：

The R7824C Rectification Flame Amplifier is a solid state plug-in 

amplifier that responds to a rectified signal from a C7024E,F SelfCheck 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 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.

ï 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.

ï Plug-in to 7800 SERIES Relay Module through printed 

circuit board edge connector keyed for proper orientation.

ï Flame signal test jacks measure amplifier flame signal 

voltage.

ï 0.0 to 5.0 Vdc Flame signal strength reading range.

ï Color coded label identifies flame detection type:

ó Greenórectification. Redóinfrared.

ó Purpleóultraviolet. Blueópulsed rectification.

ó Whiteóoptical.

ï R7847B, R7848B, R7849B Dynamic Ampli-CheckÆ 

circuitry tests all flame amplifier components 12 times per 

minute. The 7800 SERIES Relay Module locks out on 

safety shutdown with amplifier failure.

ï 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.
