Description
The Part Number 785995-01 refers to a high-quality C Series Analog Input module, specifically the NI-9235. This module is designed to offer exceptional performance with its 120ohm, 8-Channel, 24-Bit, 1/4 Bridge Input Module capabilities. It is an ideal solution for applications requiring accurate data acquisition.
The NI-9235 features 8 channels, allowing for multiple data points to be collected simultaneously. Each channel supports a sample rate of 10 kS/s, ensuring high-resolution data capture. The input range of ±29.4 mV/V is suitable for a wide variety of sensors and signals.
For safety and reliability, the module provides isolation up to 60 VDC continuous, with the capability to withstand 1,000 Vrms transient conditions. This ensures protection for both the module and the attached sensors. Additionally, it features overvoltage protection of ±30 V between any two terminals, further enhancing its durability and lifespan.
The excitation supply is integrated within the module, capable of supplying the required output current to all eight channels at minimum resistance. This feature simplifies the setup and ensures consistent performance across all channels.
Each channel is equipped with an independent, 24-bit ADC (Analog-to-Digital Converter) and an input amplifier, providing high precision and accuracy for measurements. The ground isolation feature allows the module to operate independently from earth ground, reducing the risk of interference and noise in the data.
While the module does not offer isolation between channels, as all EXC terminals connect to a common excitation supply, this design choice ensures a compact and efficient module, suitable for many applications. Additionally, the shunt calibration is software-enabled, featuring a switch and precision resistor for each channel, simplifying the calibration process and ensuring accurate readings.
