GSI127 244-127-000-017-A2-B03 Galvanic Separation Unit
Functional Description
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.
