Hi,
I've got following problem:
I want to use an output of my Ni 6528 card for swithing on vacuum valve. So... I've connected a relay to one of the output of my card, just so as it is on the picture(then the relay swithes next circuit with 24V vacuum valve).

Now, the documentation of the Ni 6528 shows follownig circuit with an isolated ground:

I am not sure if by connecting 0V om my power supply, there is already isolated ground connected to PX.Y- or not? How can I check it, or what would be "isolated ground" in my circuit?
As powersupply I use this https://www.electro-tech-online.com/custompdfs/2010/07/txl.pdf
24V 9A
As the relay I use Finder relays 55.33 series : **broken link removed**
I've observed recently(unfortunatelly), that one of my outputs is demaged and it doesn't work any more. I am not sure what is the reason of this. The current of the coil of the relay is much lower then 150mA(what is when the relay swithes on?). 6 other outputs with same relays works fine. I will appreciate any hints. Many thanks in advance for your help.
Regards,
Martin
