The NI-9226 is a resistance temperature detector (RTD) input module. You can configure the NI-9226 for two sample rate modes: high sample rate or high resolution. The NI-9226 is compatible with 3- and 4-wire RTD measurements, and it automatically detects the type of RTD (3- or 4-wire) connected to the channel and configures each channel for the appropriate mode. The module provides per-channel current excitation. The NI-9226 features calibration and includes a channel-to-earth ground double isolation barrier for safety, noise immunity, and a high common-mode voltage range.
