NI Module for Current Measurement

[shifat046]

I need some suggestions about a current module that can measure up to +3A to -3A current. Lately, I have been using NI 9203 embedded on NI cDAQ9178 for current measurement. But, it has only a range of +20mA to -20mA.

I want to measure phase currents of a 3-Phase 4-pole BLDC Motor and I have a NI cDAQ9178. Can you please suggest a good current module for this setup?

There are several stanard c-series modules that have current measurement ranges in excess of 3 amps.

Assuming you have looked at those ones, what is the limitation of them ?
