The NI‑9217 is a resistance temperature detector (RTD) input module. You can configure the NI‑9217 for two sample rate modes: high sample rate or high resolution. The NI‑9217 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‑9217 features calibration and includes a channel‑to‑earth ground double isolation barrier for safety, noise immunity, and a high common-mode voltage range.
Applications and Use Cases of NI-9217
The NI-9217 C Series RTD Input Module is a C Series module designed for high-accuracy temperature measurement using RTDs (such as PT100/PT1000). It features built-in excitation, high resolution, and channel-to-channel isolation, making it ideal for applications requiring precise, stable, and low-noise temperature acquisition.
