The National Instruments NI-9230 is a highly versatile C Series Sound and Vibration Input Module, designed for precise measurement of signals from a variety of sensors, including integrated electronic piezoelectric (IEPE) and non-IEPE types such as proximity probes, tachometers, and accelerometers. This 3-channel module has an analog input voltage range of -30 V to 30 V and can utilize smart TEDS sensors for enhanced functionality. The NI-9230 operates at a maximum sample rate of 12.8 kS/s per channel, with each channel featuring integrated anti-aliasing filters that adjust automatically based on sample rate.

Key features include software-selectable AC and DC coupling, IEPE signal conditioning, and open/short detection for enhanced reliability. The module's internal architecture incorporates a 24-bit Delta Signal Analog-to-Digital Converter (ADC), ensuring high fidelity in signal representation through a combination of analog and digital filtering techniques. Users can configure AC or DC coupling settings via software, with the option to activate or deactivate the IEPE excitation current for AC-coupled channels.

The NI-9230 is available in two versions, one with BNC front connectors (Part Number: 784396-01) and another with screw terminal connectors (Part Numbers: 783824-01 and 783824-02). It operates within a temperature range of -40 °C to 70 °C and can be stored between -40 °C and 85 °C. The module supports non-condensing humidity ranges of 10 to 90% RH for operation and 5 to 95% RH for storage, and can withstand random and sinusoidal vibrations of 5 grms and 5 g, respectively, across a frequency range of 10 to 500 Hz.

Weighing 5.6 oz for the BNC model and 5.0 oz for the screw terminal variant, both versions are designed for ease of integration into various measurement systems. The NI-9230 is compatible with NIDAQmx driver software and works seamlessly with application development environments such as LabVIEW and LabWindows/CVI. It is backed by a three-year warranty, with user and maintenance manuals available for download. For pricing information, please contact a sales representative.
