25SU5-5012 Fireye Flame Amplifier

Overview

The Fireye 25SU5-5012 is a 120 VAC high discrimination flame amplifier module designed for use with the Fireye 25SU5 control system. This module is part of a repetitive self-checking flame safeguard system that provides reliable ignition and flame failure protection by monitoring the presence or absence of a flame. It is specifically engineered for demanding industrial and commercial combustion applications where superior signal discrimination is required to distinguish between the target flame and background radiation or other burner flames.

Features

• High discrimination flame signal processing to ensure accurate detection and minimize nuisance shutdowns.
• Repetitive self-checking technology that verifies scanner and control performance 12 times per minute.
• Selectable flame failure response time (FFRT) of 1 or 4 seconds.
• Integrated safety interlock capability for single and multiple burner fired apparatus.
• Compatible with a variety of Fireye remote flame scanners, including 45UV5, 45RM, and 45FS series.
• Components include a 60-2204-2 chassis, 60-2207-2 high discrimination amplifier module, 60-2223 dust cover, 60-2301 blank display module, and 48-1805 mounting screw.

Specifications

• Operating Voltage: 120 VAC (+10%, -15%), 50/60 Hz.
• Power Consumption: 15 VA.
• Temperature Range: 32 F to 125 F (0 C to 52 C).
• Humidity: 85% RH maximum, non-condensing.
• Shutter Cycle: 0.5 seconds closed, 4.5 seconds open.
• Signal Processing: High discrimination (low sensitivity) for enhanced accuracy.

Applications

The Fireye 25SU5-5012 is utilized in safety control circuits for supervised manual and semi-automatic burner management systems. It is ideally suited for power generation, industrial process heating, and electric utility furnaces and boilers. The system supports a wide range of fuels, including natural gas, propane, oil, and pulverized coal. It is commonly applied in complex multi-burner environments where high-precision flame supervision is essential for maintaining safe and continuous operation across the entire burner load range.
