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 and R7140 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:
- 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 and 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. NOTE: R7824C, Series 2 or greater and R7847C Series 4 or greater, pulse the shutter when signal of 1.5 Vac is sensed. Display readings of 0.7 to 2.4 Vdc are common. SPECIFICATIONS
