Description
The Part Number 785995-01 refers to a C Series Analog Input module, specifically the NI-9235. This module is designed as a Strain/Bridge Input Module, equipped to handle various data acquisition needs with precision. It features an 8-Channel configuration, allowing for multiple inputs to be processed simultaneously. Each channel is capable of a Sample Rate of 10 kS/s/channel, ensuring rapid data collection and processing.
The Input Range of the NI-9235 is ±29.4 mV/V, providing a wide range of signal measurement capabilities. It also boasts a Maximum Resistance Measurement of 120 Ω, enabling it to work with a variety of sensor types and configurations. The module ensures safety and reliability with 60 VDC continuous, 1,000 Vrms transient Isolation, and Overvoltage Protection of ±30 V between any two terminals.
One of the key features of the NI-9235 is its Excitation capability, which is built-in and supplies current to all eight channels at minimum resistance. This is critical for ensuring accurate measurements across all channels. Additionally, each channel is equipped with an independent, 24-bit ADC and Input Amplifier, ensuring high-resolution data acquisition.
The module is designed with Ground Isolation, operating independently from earth ground to prevent ground loop issues and ensure signal integrity. However, it is important to note that there is No Isolation between channels; they share a common excitation supply. Lastly, Shunt Calibration is available, facilitated by a software-enabled switch with a precision resistor per channel, allowing for easy and accurate calibration of the module.
