NI-9228

The NI‑9228 performs differential analog input. With channel-to-channel isolation, your entire system, including the device under test, is protected from harmful voltage spikes up to the isolation rating. The NI‑9228 is simultaneous sampling with two options for filtering: a low-latency filter or a 50/60 Hz rejection filter. The low-latency filter enables users to use this module in industrial or control applications while getting better external noise rejection.

Applications and Use Cases of NI-9228

The NI-9228 C Series Current Input Module is a C Series analog input module designed for high-current measurement (up to 5 Arms) with channel-to-channel isolation and simultaneous sampling. It is ideal for applications requiring accurate current waveform acquisition and electrical power analysis.
