Earth terminal connected to DAQ DI,AI Gnd

Earth terminal connected to DAQ DI,AI Gnd

‎07-15-2016 04:47 AM

Hi Akshay here,

 

I am using DAQ  USB 6341  and was surprised to  find  the AI , DI Gnds  are conneted internally and the  Gnd is connected to Earth terminal thr'  the Power supply Unit provided for the DAQ.

 

I have worked with PXI modules  previously where there is total Isolation   between  Gnd and Earth.

 

any  ideas why and a workaround for the same.

 

 

regards

Akshay
