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.

PRODUCT DATA

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 rang e.

• Color coded label identifies flame detection type:

Green—rectification. Red—infrared. Purple—ultraviolet. Blue—pulsed rectification.

• 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, 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: R7824C, Series 2 or greater, and R7847C,

Series 4 or greater, pulse shutter when signal of

1.5 Vac is sensed.

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 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 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 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 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.

Flame Failure Response Time (FFRT) depends on selection of amplifier and 7800 SERIES Relay Module.

R7824C is used only with the 24 Vdc RM7824 Relay Module and C7024E,F Flame Detectors.

Circuitry tests all electronic components in flame detection system (amplifier and detector) 12 times a minute during burner operation and shuts down burner if detection system fails.

Use only Honeywell part no. 38316 Photocell.

Circuitry tests flame signal amplifier 12 times a minute during burner operation and shuts down burner if amplifier fails.

200/220/240 Vac applications require a 120 Vac, 10 VA minimum stepdown transformer (not provided) to drive the shutter. Applies to R7847C series 3 or greater; R7886A series 2 or greater; R7861 series 1 or greater. Fig. 2 shows flame detector wiring.

Use C7027, C7035 and C7044 Flame Detectors only on burners that cycle on-off at least once every twenty-four hours. Use C7012E,F Flame Detector with R7847C Amplifier, C7061A Ultraviolet Detector with R7861A Amplifier or C7076A Flame Detector with R7886A Amplifier as ultraviolet flame detection system for appliances with burners that remain on continuously for twenty-four hours or longer.

R7847A,B Amplifiers with 0.8/1 second FFRT should not be used with C7012A,C Solid State Ultraviolet Detectors.

R7824C Series 2 and greater and R7847C Series 4 and greater check flame detector system when flame reaches 1.5 Vdc or at 4.5 seconds, whichever occurs first.

Order flame rod separately; see flame detector Instructions for holder.
