Description
Honeywell R7861A1026 UV Flame Amplifier with Dynamic Self-Test (FFRT: 2.0 or 3.0 sec)
Overview
The Honeywell R7861A1026 is a solid-state, plug-in ultraviolet (UV) flame amplifier designed for use with Honeywell 7800 Series relay modules in industrial and commercial burner management systems. This amplifier provides reliable flame detection by processing UV flame signals and includes a dynamic self-check feature to continuously monitor system integrity, ensuring safe and efficient combustion control.
Key Features
-
Dynamic Self-Test: Continuously verifies detector and internal circuitry integrity, ensuring system reliability and automatic safety shutdown if a fault is detected.
-
Selectable FFRT: Supports selectable flame failure response times of 2.0 or 3.0 seconds to match system safety requirements.
-
Reliable Flame Monitoring: Processes UV flame detector inputs to confirm flame presence with a flame signal voltage range of 0.0 to 5.0 Vdc.
-
Plug-and-Play Integration: Directly plugs into 7800 Series relay modules using a keyed edge connector for secure and straightforward installation.
-
Test Jacks for Diagnostics: Built-in flame signal test jacks allow technicians to measure amplifier flame signal voltage easily during commissioning and maintenance.
-
Color-Coded Labeling: Clear identification for UV detection type to support quick field service and system organization.
-
Wide Compatibility: Works seamlessly with Honeywell UV flame detectors, including the C7061, for gas, oil, or coal burner systems.
