Product Details
The Honeywell Flame Amplifier R7847A1074 is designed for use with 7800 series and R7140 relay modules, offering a flame failure response time of either 0.8 or 3.0 seconds. It features a flame signal strength range from 0.0 to 5.0 VDC and connects to the 7800 relay module via a printed circuit board edge connector, which is keyed for proper orientation. The amplifier includes flame signal test jacks to measure flame signal voltage, and color-coded labels identify the flame detection type. It incorporates a dynamic self-check amplifier that tests the detectors and all electronic components within the flame detection system. The 7800 series relay module locks out on safety shutdown if there is a flame detection system failure. This amplifier is compatible with existing Honeywell flame detectors, which are sold separately.
