Description
The Fireye 25SU3-2100 is a rack-mounted flame safeguard amplifier for detecting the presence of flame in single- and multi-burner systems. It accepts signals from two flame scanners and evaluates them separately or together through selectable logic. Two scanner options allow different operating settings for flame discrimination.
It operates on 24VAC or 24VDC and fits standard 19" racks. The front panel includes a keypad, eight-character display, and status LEDs. Adjustable relay thresholds, response timing, 4–20mA output, and DF1 or MODBUS communication support system setup and PLC connection.
Frequently Asked Questions
Which flame scanners are compatible with the Fireye 25SU3-2100?
It supports listed 45UV5, 45RM1, 45RM2, 45RM4, 45FS1, 45UVFS1, C9701, and C9707 models, including explosion-proof and fiber-optic versions.
How does the Fireye 25SU3-2100 respond to scanner shutter failure?
The selectable SHTR CHK setting determines whether the failed scanner signal is disregarded and whether the flame relay de-energizes under the active scanner logic.
Which mounting racks accept the Fireye 25SU3-2100?
It mounts in the 60-2471-3 full rack, 60-2471-1 half rack, or 60-2530 surface-mount rack.
