Description
The NI-9235 is a product identified by the part number 151519A-02L (785995-01), which falls within the category of C Series Analog Input modules. This particular model is designed as a Strain/Bridge Input Module, offering a versatile solution for various measurement and monitoring tasks.
Equipped with 8 channels, the NI-9235 is capable of supporting measurements for 120 Ω Quarter-Bridge Strain Gage, making it a suitable choice for a wide range of applications. Each channel of the NI-9235 can sample data at a rate of 10 kS/s, providing high-resolution insights into the measured parameters.
The input range of this module is ±29.4 mV/V, ensuring a broad spectrum of signal amplitudes can be accurately captured and analyzed. With a measurement capability of up to 120 Ω, the NI-9235 is designed to accommodate a variety of strain gages and bridge inputs.
One of the key features of the NI-9235 is its robust isolation capabilities. It offers up to 60 VDC (continuous), 1,000 Vrms transient isolation, protecting the system and ensuring reliable performance even in demanding environments. The module also includes overvoltage protection of ±30 V between any two terminals, further enhancing its durability and operational safety.
The NI-9235 is designed with built-in excitation for all eight channels at minimum resistance, simplifying the setup process and reducing the need for external excitation sources. With an ADC resolution of 24-bit, independent for each channel, this module guarantees precise and accurate data acquisition, making it a powerful tool for engineers and researchers.
Additionally, the module operates in isolation from earth ground, ensuring that ground loops and interference do not compromise measurement accuracy. However, it is important to note that there is no isolation between channels; they share a common excitation supply, which should be considered when planning measurement setups.
