Description
The NI-9208 module, manufactured by National Instruments, falls within the category of C Series Analog Input devices. This module is identified by several part numbers, including 785041-01, 780968-01, and 780968-02. Notably, the version labeled with part number 780968-02 is conformal coated, offering additional protection against environmental factors.
Designed to interface with CompactDAQ/CompactRIO systems, the NI-9208 is equipped with front connectors of two types: Spring Terminal and D-Sub. This module boasts a high channel density with 16 analog input channels, and it employs a Delta-Sigma ADC type for data conversion. The input impedance is specified at 85 Ω.
In terms of electrical isolation from Earth ground, the NI-9208 ensures a level of 250 Vrms or 60 VDC, enhancing the safety and reliability of measurements. The device operates in a high-resolution mode to effectively remove 50/60 Hz noise, supporting applications that require precision and noise immunity. The maximum sample rate achievable by the module is 500 samples per second (S/s), and it utilizes a scanned sampling mode for data acquisition. With a resolution of 24-bits, the NI-9208 is capable of capturing minute changes in signal, making it suitable for a wide range of measurement and monitoring applications.
