The S3960 GSI 127 244-127-000-017 A1-B02 is a Meggitt/vibro-meter galvanic separation unit designed to transmit high-frequency AC signals, function as a safety barrier in voltage-signal measurement chains, and provide power up to 22 mA for sensor-side electronics.
V to V transfer function for voltage-signal transmission over shorter distances
Ex certified for use in potentially explosive atmospheres (hazardous areas)
Power supply for sensors and signal conditioners with a current output or a voltage output
The GSI127 is a galvanic separation unit from Meggitt’s vibro-meter product line. It is designed for operation with the signal conditioners, charge amplifiers and electronics (attached or integrated) used by various vibro-meter ® measurement chains and/or sensors.Compatible devices include the IPC707 signal conditioners (charge amplifiers) used by CAxxx piezoelectric accelerometers and CPxxx dynamic pressure sensors (and older IPC704 signal conditioners too), the IQS9xx signal conditioners used by TQ9xx proximity sensors (and older IQS4xx signal conditioners too), the attached or integrated electronics used by CExxx piezoelectric accelerometers, and the integrated electronics used by the VE210 velocity sensor.
The GSI127 is also compatible with industry standard IEPE (integrated electronics piezo electric) vibration sensors, that is, the integrated electronics used by constant-current voltage output sensors such as the CE620 and PV660 (and older CE680, CE110I and PV102 sensors too). The GSI127 galvanic separation unit is a versatile unit that can is used for the transmission of high frequency AC signals over long distances in measurement chains using current-signal transmission or as a safety barrier unit in measurement chains using voltage-signal transmission. More generally, it may be used to supply any electronic system (sensor side) having a consumption of up to 22 mA.
The GSI127 also rejects a large amount of the frame voltage that can introduce noise into a measurement chain. (Frame voltage is the ground noise and AC noise pickup that can occur between the sensor case (sensor ground) and the monitoring system (electronic ground) ). In addition, its redesigned internal power supply results in a floating output signal, eliminating the need for an additional external power supply such as an APF19x. The GSI127 is certified to be installed in an Ex Zone 2 when supplying measurement chains installed in Ex environments up to Zone 0. The unit also eliminates the need for additional external Zener barriers in intrinsic safety applications.
The GSI127 housing features removable screw terminal connectors that can unplugged from the main body of the housing to simplify installation and mounting. It also features a DIN-rail mounting adaptor that allows it to be mounted directly on a DIN rail.

When using the S3960 GSI 127 244-127-000-017 A1-B02 galvanic separation unit, strictly prevent environmental over-temperature and severe vibration to safeguard its 4 kVRMS high-voltage isolation performance. It is essential to ensure that the supply voltage and channel wiring perfectly match the downstream current-output signal modulators. Since this A1 version features a non-explosion-proof standard design, it is strictly forbidden to install it in hazardous areas with explosion risks.
This specific A1-B02 configuration is dedicated for use with IPC series signal conditioners (such as the IPC707) or IVC series velocity sensors configured with current modulation measurement chains. With a transmission sensitivity of 1 V/mA, it enables the long-distance and lossless transmission of high-frequency dynamic vibration signals via current modulation. Meanwhile, it provides robust galvanic separation and floating output capabilities, completely cutting off the ground loop between the field and the cabinet to powerfully eliminate frame voltage noise interference. Eliminating the need for an additional external power supply, it serves as a core industrial-grade hardware component that guarantees high-fidelity vibration monitoring signals for large turbomachinery.
