Description
The Part Number 778668-02 refers to a high-performance module within the PXI R Series, specifically the PXI-7831 model. This multifunction reconfigurable I/O (RIO) device is known as the NI PXI-7831R 1M Gate Multifunction RIO and is designed to cater to a wide range of applications requiring high-speed and precise data acquisition and control.
This module is equipped with 8 analog inputs (AI) and 8 analog outputs (AO), alongside a robust 96 digital I/O (DIO) terminals for versatile connectivity options. The analog inputs boast a resolution of 16 bits and can achieve a maximum sampling rate of 200 kS/s, with a conversion time of just 4 μs. These inputs are capable of handling voltage ranges of +/-10 V, with a tolerance of up to +/-42 V, ensuring flexibility and reliability in data acquisition tasks.
The analog outputs also offer a resolution of 16 bits and impress with a maximum update rate of 1 MS/s, accompanied by an update time of merely 1 μs. This high-speed performance allows for precise control signals to be generated, making the PXI-7831 an excellent choice for demanding control applications.
With 96 DIO terminals, this module provides ample digital connectivity, suitable for a wide array of digital communication and control applications. The onboard FPGA, a Virtex-II V1000, comes with 720 kbits of RAM, offering substantial space for implementing custom logic and algorithms using the LabVIEW FPGA programming interface. This allows for highly customized and efficient processing directly on the module, significantly reducing system latency and increasing overall system performance.
The PXI-7831 supports signal conditioning and I/O expansion through the NI-9151, broadening its application reach by accommodating additional sensor types and signal ranges. Despite its advanced capabilities, it’s important to note that this model has been announced
