NI 9201 voltage range

[angelmcdoggie]

Dear All,

Can I program the voltage range of NI 9201/NI 9221 even though there is only 1 nominal voltage range?

Anyway there is C function DAQmxCreateAIVoltageChan. 

I am using cDAQ-9172 & Visual C++.

Thanks and regards,

A

Hi angelmcdoggie,

You are correct that there is only one input range for the NI-9201/9221, according to the specifications. Unfortunately, this device does not have a programmable-gain amplifier, and thus you will only have the single range of ±10V for the 9201 or ±60V for the 9221. Setting the maximum and minimum input value parameters of the DAQmxCreateAIVoltageChan function to anything less than 10V and greater than -10V, respectively, will still yield a range of ±10V. Hope this helps,

Thanks for the information, Dan.
