72DUVS4 Fireye Amplifier

Overview

The Fireye 72DUVS4 is a solid-state, plug-in ultraviolet (UV) flame amplifier module designed for use with Fireye D-Series burner management controls, including the 70D10, 70D20, 70D30, 70D40, and 70D41 chassis. It is specifically engineered to work with 45UV5 series self-checking scanners. This amplifier enhances combustion safety by continuously monitoring the flame detection system for component failures during every burner firing cycle. Its self-checking capability utilizes a scanner shutter mechanism to verify the integrity of the UV tube and associated electronics, making it a critical component for industrial applications requiring high safety standards and continuous operation.

Features

• Ultraviolet Self-Check (UVSC) technology provides continuous monitoring of the flame detection system.
• Shutter-based verification checks for component failures such as a “runaway” UV tube or electronic faults.
• Plug-in design allows for easy installation and maintenance within compatible Fireye D-Series chassis.
• Built-in test jacks facilitate flame signal readout using a standard DC voltmeter.
• Reliable solid-state construction ensures longevity in demanding industrial environments.
• High discrimination capabilities for accurate flame detection.

Applications

The 72DUVS4 is primarily used in industrial and commercial burner management systems where safety and reliability are paramount. It is ideally suited for continuous or long-term burner operation, such as in steam boilers, large water heaters, and industrial furnaces. By providing a 2-4 second FFRT and repetitive self-checking, it is frequently employed in systems burning gaseous fuels or light oils where rapid detection of flame loss is necessary to prevent the accumulation of unburned fuel and potential combustion hazards.
