National Instruments NI-9217

The National Instruments NI-9217 (Part Number: 779592-01) is a high-performance C Series Temperature Input Module designed for industrial applications requiring precise resistance and temperature measurements. Featuring four 24-bit analog input channels, the NI-9217 offers exceptional precision and reliability, accommodating both three- and four-wire resistance temperature detectors (RTDs) through automatic detection and configuration. The module supports a wide operating temperature range of -200 to 850°C, utilizing a 1 mA current excitation per channel to ensure accurate readings. Its integrated circuitry effectively compensates for lead resistance in 3-wire configurations, enhancing measurement integrity.

The NI-9217 provides flexibility with two selectable sample rate modes: high-speed and high-resolution, with conversion times of 2.5 ms in high-speed mode and 200 ms in high-resolution mode. This adaptability allows users to meet varying industrial requirements for speed and accuracy. Noise immunity is a standout feature, with the module achieving noise levels as low as 0.003°C in high-resolution mode, alongside robust common-mode rejection to mitigate interference and safeguard data integrity. The design includes a ±250 Vrms common-mode voltage specification and integrated ±30 V overvoltage protection, ensuring durability across diverse electrical setups.

Furthermore, the NI-9217 is energy-efficient, consuming up to 350 mW in active mode and as low as 1 mW in sleep mode, contributing to system sustainability with minimal thermal dissipation even at elevated operating temperatures. Its Mean Time Between Failures (MTBF) is rated at 891,597 hours at 25°C, highlighting its dependability in demanding environments. Ideal for applications in manufacturing, automotive, aerospace, and energy sectors, the NI-9217 is an indispensable tool for temperature monitoring systems, quality control processes, and environmental monitoring tasks where precision is critical.
