common ground (C-GND):
All channels and the processing unit are galvanically connected. Within a crate all C-GND modules are galvanically connected.

common floating ground (CF-GND):
All channels and the processing unit are galvanically connected. The module GND is isolated from the GND of the crate. Within a crate all modules with CF-GND are galvanically isolated. A protection circuit prevents differences in the potentials between the module GND and the crate GND of greater than 60V

floating ground (F-GND):
All channels are galvanically isolated from each other and from the module GND. By default a protection circuit prevents differences in the potentials between the channels and the module GND of greater than 25V. As an option this isolation can be designed to enable potential differences from 200V up to 2,000V.
