NI-9238

The NI‑9238 performs differential analog input. The measurement range is compatible with many low-voltage sensors such as current shunts and current transducers in high-current applications. When used with higher-voltage C Series Voltage Input Modules, the NI‑9238 can measure power and energy consumption for applications such as appliance test, industrial machine monitoring, power quality analysis, phasor measurements, and harmonic analysis.
