Description
The NI-9235 is part of the C Series Analog Input category, identified by part number 785995-01. This module is designed for Strain/Bridge Input applications and features an 8-Channel configuration. It is capable of sampling rates up to 10 kS/s per channel, with an input range of ±29.4 mV/V.
The NI-9235 can measure resistance up to 120 Ω and offers continuous isolation of 60 VDC, with transient isolation reaching up to 1,000 Vrms. It is equipped with overvoltage protection that safeguards the module against voltages of ±30 V between any two terminals. Furthermore, it provides excitation current output for all eight channels, assuming minimum resistance is maintained.
Each channel of the NI-9235 boasts an independent, 24-bit ADC and input amplifier, ensuring precise data acquisition. The module also guarantees isolation from earth ground, although it does not offer isolation between individual channels. Additionally, it supports shunt calibration, featuring a software-enabled switch and precision resistor for each channel, enhancing measurement accuracy and flexibility in various application scenarios.
