Fireye 25SU3-2150 19 inch rack amplifier, 24 VAC/24VDC, high noise immunity.
The 25SU3-2150 is a Flame Safeguard Amplifier used to detect the presence or absence of a flame in a single or multi-burner environment. The 25SU3-2150 also maximizes burner discrimination with its ability to accurately differentiate the pulse rates produced by the scanners.
The 25SU3-2150 has the capacity to receive pulse inputs from two flame scanners, “A” and “B,” either separately or in combination. In addition, the 25SU3-2150 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 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 product is based on the global 3U EUROCARD format with the unit operating on either 24 VAC or 24 VDC. Fireye offers full racks and half-racks for mounting, as well as several different power supplies for various scanner/amplifier combinations. The product includes revised circuitry and is enclosed in a metal case specifically designed to enhance electrical noise rejection.
