Description
The NI-9235 is an analog input module that is characterized by its part number 779993-01 and falls under the category of C Series Analog Input. This module is specifically designed for precision measurement applications, providing a high level of detail and accuracy in data collection.
This model boasts a high-resolution 24-Bit analog-to-digital converter (ADC) that operates independently on each of its 8 channels, ensuring that signal integrity is maintained across multiple channels. The NI-9235 can sample data at a rate of 10 kS/s per channel, which allows for real-time monitoring and analysis of signals.
One of the key features of this module is its input range of ±29.4 mV/V, which offers flexibility in accommodating various signal levels. Additionally, it provides 60 VDC continuous isolation with transient overvoltage protection up to 1,000 Vrms, ensuring that the device and user are protected from unexpected voltage spikes.
The overvoltage protection feature of this module further enhances its reliability and durability by allowing it to withstand up to ±30 V between any two terminals. This is crucial for preventing damage to the module and the integrity of the data being collected in environments where voltage levels might fluctuate unexpectedly.
Moreover, the NI-9235 includes built-in excitation, which supplies output current to all eight channels at minimum resistance. This is particularly beneficial for applications that require a constant current supply for sensor excitation. Furthermore, the module supports shunt calibration, which is enabled through a software switch with a precision resistor, independent per channel. This feature facilitates easy and accurate calibration of the input channels, ensuring that the module delivers precise and reliable measurements.
In summary, the NI-9235 is an advanced analog input module that offers high-resolution data acquisition, multi-channel flexibility, comprehensive protection features, and convenient calibration options, making it an ideal choice for a wide range of precision measurement applications.
