Isolation between ground potentials
The whole internal power supply of each Irinos-Box is galvanically
isolated from the
ILink power supply . This also covers the
analogue ground AN_GND. Hence the analogue ground potentials of
two Irinos-Boxes are also galvanically isolated. All analogue inputs of
the same Irinos-Box have the same ground potential.
This separation of ground potentials prevents ground loops, which
typically lead to measurement problems. Nonetheless it is
important, that all signal sources are properly connected to the
Irinos-System.
