NI-9224

The NI‑9224 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‑9224 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-9224

The NI-9224 C Series Current Input Module is a C Series analog input module designed for industrial current measurement (4–20 mA / 0–20 mA) with channel-to-channel isolation and high noise immunity. It is ideal for applications requiring reliable current signal acquisition in industrial environments.
