• 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.
• 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
• Flame failure response time (FFRT) 2.0 or 3.0 seconds, depending on the amplifier and relay module selected.
- Temperature Range -40F to 140 F
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.
