Frequently asked questions

What type of measurement module is the NI-9219?

The NI-9219 is a four-channel isolated 24-bit high-precision general-purpose analog measurement module.

What physical quantities and sensors can the NI-9219 measure?

It can measure voltage, current, and resistance, as well as signals from strain gauges, RTDs, and thermocouples.

Can the NI-9219 channels measure different types of signals simultaneously?

Yes, because the channels are electrically isolated, all four channels can perform different types of measurements at the same time.
