The NI 9238 is a 4-channel analog input module for NI CompactDAQ and CompactRIO chassis. The measurement range of 500 mV can be used with many low-voltage sensors such as current shunts and current transducers in high-current applications. 

When used with the NI 9225, NI 9242, or NI 9244 high-voltage modules, the NI 9238 module can measure power and energy consumption for applications such as appliance test, industrial machine monitoring, power quality analysis, phasor measurements, and harmonic analysis.
