SIRIUS®
5.2.4 Isolated version: USB
The (standard) SIRIUSi modules are isolated between themselves and the main board.
Some modules generate power for electronics and for external pins: this power supply is again isolated against other
modules, the main board and the housing.
Inside of one module, the power supply pins, counter and analogue inputs are not isolated between themselves (they
have the same ground) that is available on the GND connector pin (e.g. The analogue input and the counter of one
ACC+ module share the same GND).
