Description
Honeywell R7847B1031 Rectification Flame Amplifier with Ampli-Check for 7800 Series, 2.0/3.0 sec FFRT Overview The Honeywell R7847B1031 is a solid-state, plug-in rectification flame amplifier designed to detect flame presence in industrial and commercial burner systems. Engineered for use with Honeywell 7800 Series relay modules, this unit features Ampli-Check self-testing to ensure continuous operational safety and system reliability. Key Features Ampli-Check Self-Test: Continuously monitors amplifier and flame detection components; triggers safety lockout if a fault is detected. Selectable Flame Failure Response Time: 2.0 or 3.0-second flame failure response time options for flexible safety settings. Flame Signal Strength Monitoring: Measures flame signal voltage from 0.0 to 5.0 Vdc for precise diagnostics and commissioning. Plug-In Design: Easily installs into Honeywell 7800 Series relay modules via keyed printed circuit board edge connector for secure and error-free connection. Color-Coded Labeling: Identifies detection type for quick and accurate service in multi-system environments. Compatible: Works with Honeywell flame detectors (ordered separately) to provide robust flame supervision. Typical Applications Burner management systems requiring rectification flame detection with self-check capabilities. Industrial and commercial boilers and furnaces utilizing Honeywell 7800 Series relay modules. Systems demanding continuous verification of flame presence and amplifier integrity for safety compliance.
