Description
The NI PXI-7831R 1M Gate Multifunction RIO, with part number 188133K-01L, falls under the PXI R Series category. This model is designed to cater to a wide range of applications, thanks to its robust set of features which include 8 analog inputs (AI), 8 analog outputs (AO), and 96 digital I/O (DIO). The analog inputs have a resolution of 16 bits and can handle a maximum sampling rate of 200 kS/s, with a conversion time of 4 μs. The input voltage range is quite flexible at +/-10 volts, ensuring compatibility with a variety of sensors and signals. Moreover, the device can withstand a maximum input voltage of +/-42 V without sustaining damage, and operates safely within a maximum working voltage of +/-12 V.
On the analog output front, the PXI-7831R impresses with an update rate of 1 MS/s and a swift update time of 1 μs, allowing for precise control signals to be generated. The heart of this module is the Virtex-II V1000 FPGA, accompanied by 720 kbits of FPGA RAM, which together provide substantial firepower for implementing complex logic and signal processing algorithms directly on the module through the LabVIEW FPGA programming interface.
Additionally, the PXI-7831R supports signal conditioning and I/O expansion through the NI-9151 module, enhancing its versatility and making it suitable for a wide array of applications. Despite being announced as obsolete by National Instruments, this module remains available for purchase and repairs through Apex Waves, ensuring that existing systems can continue to benefit from its advanced capabilities.
