Description
The product with the Part Number 785995-01 falls under the Category of C Series Analog Input. It is specifically the Model NI-9235, which features a NI 9235 Spring Terminal, 8 Channel Quarter-Bridge Input. This model is designed to accommodate 8 channels, making it versatile for a range of applications.
It boasts an impressive Sample Rate of 10 kS/s/channel, ensuring high-speed data acquisition. The Input Range is quite flexible, at ±29.4 mV/V, which allows for a broad spectrum of signal strengths to be accurately measured. Safety features include Isolation at 60 VDC (continuous), 1,000 Vrms (transient), offering protection against unexpected voltage spikes. Additionally, the Overvoltage Protection is rated at ±30 V between any two terminals, further safeguarding the device from electrical damage.
The Excitation Supply is thoughtfully built-in, catering to all eight channels at minimum resistance, which simplifies the setup process. Each channel is equipped with an Independent, 24-bit ADC, ensuring high-resolution data acquisition. Moreover, there is an Input Amplifier for each channel, enhancing the signal quality.
When it comes to grounding, the Ground Isolation feature ensures that the device is Isolated from earth ground, minimizing noise and interference. However, it’s important to note that there is No isolation between channels, as they share a common excitation supply. This design choice might influence how signals are processed and separated.
Lastly, the Shunt Calibration mechanism is facilitated by a software-enabled switch and precision resistor per channel, allowing for accurate and easy calibration of the device.
