4 kVRMS galvanic separation between the sensor side and the monitor side
50 VRMS galvanic separation between the power supply and the output signal (floating output)
High rejection of frame voltage
µA to mV transfer function for current-signal transmission over longer distances
V to V transfer function for voltage-signal transmission over shorter distances
Ex certified for use in potentially explosive atmospheres (hazardous areas)
Compatible with industry standard IEPE (integrated electronics piezo electric) vibration sensors

GSI127 DESCRIPTION

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.

The GSI127 galvanic separation unit is a versatile unit that can is used for the transmission of highfrequency 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 (nA) when supplying measurement chains installed in Ex environments up to Zone 0 ([ia]). The unit also eliminates the need for additional external Zener barriers in intrinsic safety (Ex i) applications.

The GSI127 housing features removable screwterminal 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.
