The National Instruments NI-9226 is a C Series Temperature Input Module designed for high-performance temperature measurement applications. This module features eight differential analog input channels with an aggregate sampling rate of 400 samples per second, offering compatibility with PT1000 RTDs and thermocouples. The NI-9226 operates with adjustable configurations, allowing users to select between high sample rate and high resolution modes to suit varied application needs. It integrates seamlessly with CompactDAQ and CompactRIO systems, and provides per-channel current excitation, ensuring accurate temperature readings.

This module is capable of handling 3- and 4-wire resistance temperature detector (RTD) configurations, automatically detecting the wire type and adjusting the channel setup accordingly. Additionally, the NI-9226 is equipped with features such as open-thermocouple detection, cold-junction compensation, and channel-to-channel isolation for enhanced operational reliability. Users can choose between two calibration modes: Calibrated for stable, precise readings in ohms, and Raw for accessing uncalibrated data, which can be converted into temperature values when processed.

The NI-9226 is built to withstand harsh environments, offering an operating temperature range from -40 to 70 °C and a storage range from -40 to 85 °C. It also maintains performance in humidity levels from 10 to 90% RH during operation and 5 to 95% RH during storage. With a weight of 5.7 oz for the spring terminal model and 5.04 oz for the D-Sub connection version, the NI-9226 is lightweight yet robust. The module is backed by a three-year warranty, with user and maintenance manuals available for comprehensive support. For pricing inquiries, please contact a sales representative.
