What is the maximum power on NI usb 6210 ?

[gumus]

Hi all,

I have to measure 400VAC i need therefore a transformator,which makes the voltage lower than -+10V.i need to know maximum power and maximum current for the ni usb 6210,so that i can order the suitable transformator.

Can anybody help me for it ?

thank you!

thank you!

Input current during overvoltage condition -+20mA max/AI pin,so that means maximum current for my DAQ device right?

Input current during overvoltage condition

±20 mA max/AI pin

Hi Gumus,

the Input current during overvoltage condition doesn't contain the information, which you are serching for. If you look in the Datasheet, you will find the following Information:

If the input voltage is approximately 10V, than you can calculate the input current I=U/R= 10V / 10G Ohm = 1nA. Like you see, you don't have to calculate the input current or input power of the NI USB-6210, because the input resistance is so big.
