compactdaq ground

[nobody725]

I have a compactdaq cDAQ9172 and the following boards:

NI9205, NI9263, NI9425, NI9477

All of them are stated ch-ground isolation.  I know that the ch-ground is isolated from the PC ground.

Are these ch-grounds isolated to each other or they still share a common ground but isolated from the PC ground.

Because each of above module will be connected to different sources.  I don't want these module boards to have common ground.

Thanks

Hi,

I just know that the C-Series Modules within a cRIO Chassis are isolated from each other, so everyone has it's own ground.

I assume it's the same with a cDAQ module, however let me check this.

Hi,

All Modules, except NI 9233/34 and NI 9402 are isolated from the chassis and the other modules.
