NI-9225

The NI‑9225 performs differential analog input. The wide measurement range is well suited for high-voltage measurement applications such as power metering, power quality monitoring, motor test, battery stack testing, and fuel cell tests. You can perform transient and harmonic analysis with high-speed simultaneous sampling. In addition, you can prevent ground loops and add safety to a system with 600 Vrms channel‑to‑channel isolation between the three NI‑9225 channels.
