Fireye 25SU3-2100 19 inch rack amplifier, 24 VAC/24VDC.
The 25SU3-2100 is a Flame Safeguard Amplifier used to detect the presence or absence of a flame in a single or multi-burner environment. The 25SU3-2100 also maximizes burner discrimination with its
ability to accurately differentiate the pulse rates produced by the scanners.
The 25SU3-2100 has the capacity to receive pulse inputs from two flame scanners, “A” and “B,” either separately or in combination. In addition, the 25SU3-2100 has two logic programs available, called
“Scanner Option 1” and “Scanner Option 2.” Within these two scanner options, the user may select different operating parameters, and select the scanner or scanners that will provide the pulse input for
that option. Switching between “Scanner Option 1” and “Scanner Option 2” is accomplished by an external dry contact input to the amplifier. The dynamic range for the 25SU3-2100 amplifier is 1900
pulses per second, which is consistent with the output range provided by Fireye scanners. The pulse rate output of each scanner can be checked by the user, thus facilitating the maintenance of each
scanner.
The design platform of the 25SU3-2100 is based on the global 19 inch format with the unit operating on either 24 VAC or 24 VDC. Fireye offers a full rack (60-2471-3), half-rack (60-2471-1) or surface
mount rack (60-2530), and filler plates for mounting the 25SU3-2100 amplifiers, as well as several different power supplies for various scanner/amplifier combinations.
