R7861A1026 | Honeywell | Flame Amplifier

The Honeywell R7861A1026 is a dynamic self-checking ultraviolet flame amplifier designed to plug into Honeywell 7800 Series relay modules. It monitors flame detector inputs to verify the presence of combustion, providing flame failure response times of 2.0 or 3.0 seconds while executing continuous self-checks on both system electronics and connected detectors.

Functionality and Signal Monitoring

This solid-state plug-in module interfaces with 7800 Series relay modules via a keyed printed circuit board edge connector for correct orientation. It features integrated flame signal test jacks that allow technicians to measure amplifier DC voltage ranging from 0.0 to 5.0 Vdc. The purple color-coded label identifies its specific dynamic self-check ultraviolet detection type, triggering a safety shutdown if any component or detector failure occurs.

System Compatibility

The amplifier is specifically engineered for use with Honeywell C7061 ultraviolet flame sensors across gas, oil, or coal burner applications. It operates in conjunction with 7800 Series primary safety control relay modules to maintain reliable flame supervision and safety interlocks.
