Overview

Product overview

Key product information and technical features.

The NI-9216 provides RTD temperature acquisition within a CompactDAQ system. NI lists it as a general-purpose PT100 temperature measurement option in its CompactDAQ system build guide.

Selectable high-speed and high-resolution modes balance acquisition speed against measurement noise. Channels share an isolated common ground; they are not individually isolated.

Automatic detection of 3-wire or 4-wire RTD connections.
Built-in 1 mA excitation per channel.
50/60 Hz normal-mode noise rejection in high-resolution mode.
