Hello,
we would like to connect 4 different external signals to the input ports of the 4DI4DO module while we need to keep the netPI galvanically isolated against the input ports andalso the input ports need to stay galvanically isolated to each other input port.
This is not possible with the 4DI4DO module, right?
The module itself requires 24V DC so we need one 24DC power for the netPI and another galvanically isolated one for the 4DI4DO module. But each input port is connected together and with the power source for the 4DI4DO module.
But we are able to connect one external signal which will then stay galvanically isolated to the netPI if the both power sources are. Right?
We need to connect really expensive hardware and must ensure that a mayor fault will not harm the other systems.
Thanks for the clarification.
Best,
Manuel
