The NI 9227 C Series current input module was designed to measure 5 Arms nominal and up to 14 A peak on each channel with channel-to-channel isolation.

When used with the NI 9225 high-voltage module, the NI 9227 current module can measure power and energy consumption for applications such as appliance and electronic device test. With up to 50 kS/s per channel simultaneous sampling, you can not only measure and meter current and power but also look at quality factors such as noise, frequency, and harmonics.
