GSI124 244-124-000-021 Galvanic separation unit

The versatile GSI 124 galvanic separation unit replaces
its predecessors: GSI 122, GSI 123 and GSI 130. The
GSI 124 is for use with piezo-electric transducers with
integrated electronics (eg. CE XXX), piezo-electric transducer signal conditioners (eg. IPC XXX) and proximity
probe signal conditioners (eg. IQS 4XX series).
The unit is intended for use in 2-wire transmission systems at high frequencies. More generally, it may be used
to supply any electronic system having a consumption of
less than 20 mA.
The GSI 124 avoids the use of Zener barriers for Exi
applications. It allows the transmission of AC signals
over long distances. The unit rejects a large amount of
the RMS voltage of ground noise and avoids AC noise
pickup which can occur between the sensor case and
the poles of the sensor.
