188133J-01

Description

The NI PXI-7831R is a multifunction RIO device with a part number 188133J-01 and falls under the PXI R Series category. Manufactured by National Instruments, this device is designed to be a versatile tool in any engineer’s toolbox, thanks to its reconfigurable I/O capabilities.

At the heart of the PXI-7831R lies the Virtex-II V1000 FPGA, which offers a generous 720 kbits of RAM, enabling complex data processing and control algorithms to be executed directly on the device. This FPGA is integral to the device’s multifunction capabilities, allowing for high-speed and precise control and measurement tasks.

The device boasts 8 analog inputs, each with 16 bits of resolution, capable of sampling rates up to 200 kS/s, and a conversion time of just 4 μs. The input range is a flexible ±10 volts, with a maximum input voltage tolerance of ±42 V, ensuring a wide range of sensors and signals can be accommodated. Additionally, the PXI-7831R features 8 analog outputs, also with 16-bit resolution, providing a maximum update rate of 1 MS/s and an update time of 1 μs, enabling quick and accurate actuation or signal generation tasks.

Complementing the analog capabilities are 96 digital I/O terminals. These terminals are programmable, allowing them to function as inputs, outputs, counters/timers, or for custom logic, offering unparalleled flexibility in interfacing with a variety of digital devices and sensors.

Programming the PXI-7831R is made accessible through the LabVIEW FPGA module, which allows developers to design custom logic and control algorithms, further enhancing the device’s adaptability to specific application needs. Moreover, the device supports signal conditioning and I/O expansion when interfaced with the NI-9151 module, giving users the ability to scale their systems according to project requirements.
