The NI ‑ 9216 is an RTD input module. It can be configured for two different sample rate modes: high sample rate or high resolution. The NI ‑ 9216 supports 3 and 4 wire RTD measurements. It automatically detects which RTD type (3 or 4-wire) is connected to the channel and configures each channel accordingly. The module supplies excitation current per channel. The NI ‑ 9216 also has a calibration certificate and double insulation of the channel from ground, which ensures increased operational reliability, noise immunity and a high common-mode voltage range.
