I would like to purchase a cDAQ-9185 chassis and 4 modules type NI 9231 (8 channel IEPE, 24 bits, 51.2 kHz max.):

https://www.ni.com/en-us/shop/model/ni-9231.html
Now I would like to clarify in advance whether I can then operate the total of 32 channels with the full sampling rate of 51.2 kHz without running into any trouble.
I could not find anything in the datasheets that contradicts this, simulation runs as well.
The 1Gbit network connection should not be a problem:
Net data rate: 4 modules * 8 channels * 51.2 kHz * 24 bits/sample = 37.5 Mbit/s
Can anyone confirm to me that this is safe?
Thank you very much!

Your calculation is about right - https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019QYVSA2&l=en-US
37.5Mb/s doesn't seem too much and much within Ethernet capabilities unless your local network is too much loaded.
