Description
The NI-9226 is identified by its part number 157643D-01L, which also has alternative identifiers including 785189-01, 783864-01, 783864-02, 783704-01, and 157643A-01L. This module falls under the C Series Analog Input category and is designed specifically for precise data acquisition tasks.
The NI-9226 features 8 channels and boasts a sample rate of 400 S/s aggregate, making it capable of handling multiple signals simultaneously. It supports a wide resistance range from 0 Ω to 4000 Ω, ensuring versatility across various applications. The module’s resolution is a high 24-Bit, offering detailed and accurate readings.
One of the standout features of the NI-9226 is its accuracy, which reaches up to 0.15 °C analysis efficiency. This makes it an ideal choice for applications requiring precise temperature measurements. Users can select between high example rate or high resolution modes depending on their specific needs, further enhancing the module’s flexibility.
The NI-9226 is equipped with an OTL configuration that automatically detects 3- or 4-wire OTL, simplifying setup and reducing potential configuration errors. When it comes to data, the module offers two calibration mode options: Calibrated, which returns calibrated, fixed-point data in ohms, and Raw, which returns uncalibrated, binary values. This allows users to choose the data representation that best suits their analysis requirements.
In terms of physical specifications, the module comes in two models with different weights. The Spring Terminal Model weighs 5.7 oz, whereas the DSUB Model is slightly lighter at 5.04 oz. This difference in weight provides options for system designers to select the model that best fits their hardware configuration needs.
