Would it be possible to modify SC-2040 so one can connect mA signal to the input instead of V signal? Anyone has tried to do it? Any comment welcomed. Thanks.
Check out the link below. This should work with the SC-2040. I hope this helps.

Thanks toddd, Sure it does help. We can see that SCXI boards have space for precision resistor. However, I am not sure if I can do the same with SC-2040. Circuit-wise it should work, yet my concern is physical location.
