Vibro-Meter S3960 GSI 127 244-127-000-017 A1-B02 galvanic separation unit

Description

The Vibro-Meter S3960 GSI127 244-127-000-017 A1-B02 is a GSI127 galvanic separation unit designed to provide electrical isolation between vibration sensors and monitoring systems. It supplies power to compatible signal conditioners and sensors with either current or voltage outputs while ensuring reliable signal transmission in industrial condition monitoring systems. The unit features 4 kVRMS galvanic isolation between the sensor side and monitor side, 50 VRMS isolation between the power supply and output (floating output), high frame-voltage rejection, and supports both µA-to-mV transfer for long-distance current signal transmission and V-to-V transfer for short-distance voltage signal transmission. It is compatible with standard IEPE vibration sensors and is available in Ex-certified versions for hazardous-area applications.
