Description
The NI PXI-7831R 1M Gate Multifunction RIO, part number 188133G-01, falls within the PXI R Series category. This model, the PXI-7831, is designed to offer a comprehensive solution for data acquisition and control applications.
It is equipped with 8 Analog Inputs (AI) and 8 Analog Outputs (AO), alongside a significant number of 96 Digital I/O (DIO) channels. These features enable versatile and complex signal processing capabilities. The input resolution for analog signals is 16 bits, ensuring high precision in measurements.
The maximum sampling rate for analog inputs reaches up to 200 kS/s, with a conversion time of just 4 µs. This allows for rapid data acquisition, critical in time-sensitive applications. The input signal range is +/-10 volts, providing flexibility in handling various signal levels. However, it can withstand up to +42 V without damage, although the recommended working voltage for analog inputs is below 12 V.
For analog outputs, the maximum update rate is 1 MS/s, with an update time of 1 µs, facilitating quick response times in control applications. The onboard FPGA, a Virtex-II V1000, offers 720 kbits of RAM, enabling complex, real-time signal processing and control algorithms.
The device supports programming through the LabVIEW FPGA module, offering a flexible and powerful environment for developing custom applications. It is also compatible with NI-9151 for signal conditioning and I/O expansion, further extending its utility in various scenarios.
Despite its Obsolete Status announced by National Instruments, it remains available at Apex Waves, providing a valuable resource for users requiring robust and reliable data acquisition and control solutions.
