25SU5-5013 Fireye Flame Amplifier

Overview

The Fireye 25SU5-5013 is a high-sensitivity, self-checking flame amplifier designed for industrial burner management and flame safeguard systems. This modular unit confirms the presence or absence of flame to provide reliable ignition and flame failure protection. It is specifically engineered with high sensitivity and no hysteresis, making it ideal for applications with minimal differences between flame signals and background radiation. The system typically consists of a 60-2204-2 chassis, a 60-2207-3 high-sensitivity amplifier module, and a 60-2301 blank display module.

Features

• Repetitive Self-Checking: Automatically verifies scanner and control performance 12 times per minute to prevent false flame signals.
• High Sensitivity & Low Hysteresis: Optimized for accurate detection in challenging environments where discriminating between flame and background is difficult.
• Dual Scanner Support: Capable of monitoring and analyzing inputs from two separate flame scanners simultaneously.
• Dual Gain Settings: Features independent “Sensitivity A” and “Sensitivity B” adjustments to accommodate different fuel types or dual-scanner configurations.
• Selectable FFRT: The Flame Failure Response Time is adjustable to meet specific safety and compliance requirements.
• Signal Diagnostics: Includes 0–3 VDC test jacks for real-time monitoring of flame signal strength and built-in safe start checks.

Applications

The 25SU5-5013 is used in integrated safety interlock systems for single and multiple burner-fired apparatus, including power plants, industrial process heating, and electric utility furnaces. It is designed for continuous firing of gas, oil, pulverized coal, or multi-fuel combinations. This control is frequently employed as the primary safety device in supervised manual and semi-automatic burner management systems, providing comprehensive flame supervision throughout the entire burner load range.
