R7849A1023

The Honeywell R7849A1023 flame amplifier 2 OR 3 SEC Flame FAILURE RESPONSE TIME.

Datasheet

Installation Guide

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

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 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, R7851B, R7852B Dynamic Ampli-Check® circuitry tests all flame amplifier components 12 times per minute. The 7800 SERIES / R7140 Relay Module locks out on safety shutdown with amplifier failure.
• R7824C, 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 and R7140 Relay Module locks out on safety shutdown with flame detection system failure.
