The NI-9216 C Series Temperature Input Module from National Instruments is designed for precise temperature measurements in industrial environments. Available in multiple configurations (Part Numbers: 783863-01, 783863-02, and 785186-01), this module accommodates a range of application needs with options for 60 Vrms or 250 Vrms channel-to-earth ground isolation. The device features eight differential analog input channels, allowing for efficient data acquisition at a maximum sampling rate of 400 samples per second and a resolution of 24 bits. Users can operate the module in two modes: high sample rate or high resolution, enabling optimized performance tailored to specific measurement requirements.

The NI-9216 supports PT100 RTD sensors, facilitating the detection and measurement of resistance temperatures with high accuracy. Each channel can be independently excited to enhance measurement fidelity, while the module supports integration with software such as the LabVIEW Professional Development System, LabVIEW FPGA Module, and LabVIEW Real-Time Module. The module offers a scanned mode of operation and exceptional conversion times of 200 ms per channel or 1600 ms for all channels in high resolution mode. In high-speed mode, conversion times are significantly reduced to 2.5 ms per channel and 20 ms for all channels.

The NI-9216 effectively measures resistance ranging from 0 to 400 ohms, making it a versatile choice for meeting industrial quality standards. It is housed in durable enclosures, weighing 5.7 ounces for the spring terminal model and 5.04 ounces for the D-Sub version. The recommended operating temperature ranges from -40 °C to 70 °C, with a storage temperature range of -40 °C to 85 °C. The module operates effectively in varying humidity conditions of 10% to 90% RH, and can withstand vibrations of 5 grms for random and 5 g for sinusoidal at frequencies between 10 to 500 Hz. The NI-9216 is backed by a three-year warranty, with user and maintenance manuals available for download to assist with installation and operation.
