Description：
Vibro-Meter GSI127 244-127-000-017 A1-B02 is a galvanic separation unit from the vibro-meter® product line, designed to provide power supply, signal isolation, and signal transmission for vibration monitoring measurement chains. The unit is used with signal conditioners, charge amplifiers, proximity sensor conditioners, velocity sensors, piezoelectric accelerometers, dynamic pressure sensors, and IEPE vibration sensors. It provides 4 kVRMS galvanic isolation between the sensor side and monitor side, ensuring reliable signal transmission while protecting monitoring systems from ground loops, electrical noise, and frame voltage interference.
The GSI127 supports both current-output and voltage-output measurement chains. It can transmit high-frequency AC signals over long distances using current-signal transmission and can also function as a safety barrier in voltage-signal transmission systems. The floating output design eliminates the need for an external power supply barrier, simplifying installation and improving measurement reliability.
