Product Details
The Honeywell flame amplifier R7851B1018 is designed for use with 7800 series and R7140 relay modules, offering a flame failure response time of 0.8 or 3.0 seconds and a flame signal strength range from 0.0 to 5.0 VDC. It plugs into the 7800 relay module through a printed circuit board edge connector that is keyed for proper orientation, and includes flame signal test jacks to measure amplifier flame signal voltage. Color-coded labels identify the type of flame detection, while the dynamic self-check amplifier tests both the detectors and all electronic components within the flame detection system. The 7800 series relay module locks out on safety shutdown if a flame detection system failure occurs. This amplifier is compatible with existing Honeywell flame detectors, which are ordered separately. The product includes a warranty with specified terms.
