72DRT1 Fireye Flame RECTIFICATION Amplifier

Overview

The Fireye 72DRT1 is a high-performance, plug-in flame rectification amplifier module designed for use with Fireye D-Series burner management controls. This solid-state component is engineered to provide reliable ignition and flame failure protection for manually started or semi-automatic oil and gas burners. By selecting the rectification method of flame detection, it ensures accurate monitoring of the combustion process through the use of flame rods or specific photocells.

Features

• Solid-state design for enhanced reliability and long service life in industrial environments.
• Plug-in module format allows for easy installation and quick selection of flame detection methods within the D-Series chassis.
• Flame rectification technology specifically designed for use with flame rods or 45CM1 photocells.
• Integrated safe-start check prevents burner startup if a flame signal (real or simulated) is detected during the start cycle.
• Built-in test jack for convenient voltage monitoring and troubleshooting.

Specifications

• Model Number: 72DRT1
• Detection Type: Flame Rectification (RT)
• Flame Failure Response Time (FFRT): 2 to 4 seconds
• Compatibility: Fireye D-Series controls (such as D40, D41)
• Input Sensors: 69ND1 flame rods or 45CM1 photocells
• Test Jack Voltage: 15 to 25 VDC (normal operating range)
• Weight: Approximately 1.0 lb

Applications

The 72DRT1 is primarily used in commercial and industrial combustion systems to provide flame safeguard protection. It is ideally suited for monitoring flames from gaseous fuels using flame rods (rectification) or light oil flames when paired with compatible photocells. Common applications include boilers, furnaces, and ovens where precise flame sensing and moderate response times are required for safe operation.
