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.

The chassis provides rugged, modular housing for your controller (if using CompactRIO) and C Series modules. A high-performance backplane in the chassis contains the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your C Series modules. If you are using the NI CompactDAQ platform, then a Personal Computer (PC) will act as the controller of your system. However, if the CompactRIO platform is used then an embedded real-time controller will be used instead.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This device is compatible with a different programming languages depending on the platform used. If you are using the NI CompactDAQ platform then this device is compatible with LabVIEW, C/C++, Visual Basic, and .NET. However, if the CompactRIO platform is used then this device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware).
