Fireye 25SU3-5168 Flame Safeguard Amplifier 120/230 VAC High Sensitivity

The Fireye 25SU3-5168 is a high sensitivity flame safeguard amplifier designed to confirm the presence or absence of flame in industrial and utility combustion applications. This control provides reliable ignition and flame failure protection for systems incorporating single and multiple burner firing apparatus.

Key Features:

• Operates on 120/230 VAC dual voltage
• High sensitivity amplifier ideal for applications with large scanner pulse ratios (>3:1 flame-on to flame-off)
• Provides flame safeguard interlock capability for burner management systems
• Monitors flame throughout entire burner firing cycle
• Proves presence of flame during normal start-up and operation
• Provides primary shutdown contact in event of ignition or flame failure
• Compatible with Fireye UV and infrared flame scanners including 45UV5, 45RM1, 45RM2, 45RM4, 45FS1, and 45UVFS1 models

Complete System Components:

• 60-2203-2: Control chassis
• 60-2207-1: High sensitivity flame amplifier module
• 60-2301: Timer module

Typical Applications:

• Power generation facilities
• Industrial process heating
• Pulp and paper mills
• Chemical plants
• Electric utility furnaces and boilers firing gas, oil, pulverized coal, or combination fuels
• Supervised manual and semi-automatic burner management systems

During operation, the control activates auxiliary equipment to indicate flame status and permit fuel delivery and ignition. The primary shutdown contact enables visual indication, alarm functions, ignition power shutdown, and fuel shutoff valve control in the event of flame failure.
