Description
The Part Number for this product is 785995-01. It falls under the Category of C Series Analog Input, specifically the Model NI-9235. This model is described as the NI 9235 Conformal Coated, 8 Channel Quarter-Bridge Input, highlighting its capability to handle multiple inputs efficiently.
It features 8-Channel inputs, making it versatile for various applications. The Sample Rate is quite high at 10 kS/s/channel, ensuring quick data collection. The Input Range is also very accommodating at ±29.4 mV/V, suitable for a wide range of measurement needs.
The device is designed to work with 120 Ω Quarter-Bridge Strain Gage, showing its compatibility with standard sensors. Isolation is robust, with 60 VDC (continuous), 1,000 Vrms transient protection, ensuring safety and reliability. It also features Overvoltage Protection of ±30 V between any two terminals, adding an extra layer of security for the device.
One of the notable features is the Excitation Current Output, which is provided to all eight channels at minimum resistance. This is crucial for precise measurements. The ADC and Input Amplifier are independent and feature a 24-bit resolution per channel, ensuring high-quality data acquisition.
The device has Ground Isolation, meaning it is isolated from earth ground, which is critical for preventing ground loops and ensuring accurate measurements. However, it’s important to note that there is No isolation between channels; they share a common excitation supply. Lastly, the Shunt Calibration feature is software-enabled, with a precision resistor per channel, allowing for easy calibration and maintenance.
