FIREYE 25SU3-2000 Overview
The 25SU3-2000 is a Flame Safeguard Amplifier used to detect the presence or absence of a flame in a single or multi-burner environment. The 25SU3-2000 also maximizes burner discrimination with its ability to accurately differentiate the pulse rates produced by the scanners. The 25SU3-2000 has the capacity to receive pulse inputs from two flame scanners, “A” and “B,” either separately or in combination. In addition, the 25SU3-2000 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 25SU3-2000 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 25SU3-2000 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 25SU3-2000 amplifiers, as well as several different power supplies for various scanner/amplifier combinations. See Ordering Information. The 25SU3-2000 amplifier provides remote communications capability to a PLC using either Allen-Bradley DF1 or MODBUS communication protocol. Consult factory for details.
