GSI130 244-130-000-204 Galvanic Separation Units
Description:
The GSI130 galvanic separation unit is used for supplying transducers and conditioners and for reading off signals given by them. 
It is used in 2-wire transmission systems. In a more general application it serves for supplying any electronic system with a consumption of less than 20 mA.
This unit outputs a voltage signal proportional to the current consumed by the conditioner. This voltage signal is directly available for analysis of the conditioner signal.
The GSI130 module avoids any problems due to voltage differences between the measuring point
and the signal processing (e.g. earth loops).
The use of the GSI130 in an installation avoids the need to mount Zener barriers, which  generate additional voltages drops and limit the length of the transmission line and the dynamic range of the system.
