Hello Manuel,
your understanding is absolutely right.
With the DIO module the intension was
a.) not to load the netPI's internal power supply with additional power/current needed on the DO side
b.) galvanic isolation of the DI's and DO's
This is why we decided to shift the "load problem" to the module itself by giving the user the option to power it with any power supply he wants
And yes, in best case you have two power supplies, one for netPI and one for the DOs with no common GND to keep netPI isolated.
Thx
Armin
