Fireye 25SU3-2000 Amplifier

The Fireye 25SU3-2000 Amplifier is a high-performance 19-inch rack-mounted flame safeguard amplifier specifically engineered to detect flame presence in complex single or multi-burner environments. As a veteran-grade flame signal amplifier, this unit excels in burner discrimination by accurately differentiating pulse rates between 0 and 1900 pulses per second, ensuring precise flame safeguard control even in high-interference settings. The hardware supports dual-channel inputs, allowing for the simultaneous analysis of signals from two Fireye flame scanners, designated as "A" and "B," with independent logic programs for specialized firing sequences.

Operating on a flexible 24 VAC/VDC power platform, the 25SU3-2000 features a robust keypad entry system with password protection to prevent unauthorized field adjustments. Technicians can utilize the integrated 4-20mA analog output for real-time flame signal strength monitoring and scalable remote diagnostics. With its CE Approved status and Modbus RTU communication capabilities, this amplifier integrates seamlessly into modern PLC or SCADA architectures for comprehensive burner management. For total system reliability, the unit includes adjustable Flame Failure Response Time (FFRT) settings ranging from 1 to 6 seconds and independent relay pull-in thresholds.

• Enhanced Burner Discrimination: Advanced pulse rate differentiation prevents nuisance shutdowns in multi-burner arrays.
• Dual Scanner Input: Capable of managing two separate flame scanners with selectable logic for versatile monitoring.
• Industrial Digital Communication: Supports remote monitoring via Modbus or Allen-Bradley protocols for streamlined system integration.
• Tactical User Interface: Features an eight-character alpha-numeric display and front-panel LEDs for immediate status verification.
• Customizable Timing: Fully adjustable flame relay delay (0 to 10 seconds) and FFRT windows to match specific site requirements.

• Can this amplifier be retrofitted into older rack systems? Yes, the unit is designed for a standard 19-inch global format and is compatible with 192SU3 modernization adapters for legacy wiring racks.
• What types of scanners are compatible with the 25SU3-2000? It supports various Fireye scanners, including 45UV5, 45RM1, 45RM2, and 45RM4, as well as fiber optic and explosion-proof versions.
• How do I check individual scanner outputs? The pulse rate output for each scanner can be checked directly through the keypad interface, allowing for preventative maintenance without specialized tools.
