Description
The NI PXI-7831R is a versatile and high-performance multifunction RIO device with the part number 188133B-01. It falls under the PXI R Series category and is designed to meet a wide array of system requirements.
The model PXI-7831 has a comprehensive description that encapsulates its capabilities: NI PXI-7831R 1M Gate Multifunction RIO (8 AI, 8 AO, 96 DIO), indicating its multifaceted nature. This device boasts 8 analog inputs (AI) with 16 bits resolution, offering a sampling rate of up to 200 kS/s. The conversion time is remarkably swift at 4 μs, with an input range of +/- 10 volts. It’s built to withstand a maximum input voltage of +/- 42 V without sustaining damage, though it’s recommended to operate at a working voltage of less than +/- 12 V for optimal performance.
In addition to its impressive analog input capabilities, the PXI-7831R features 8 analog outputs (AO), each with 16 bits of resolution and a maximum update rate of 1 MS/s. The update time is incredibly fast at 1 μs, enabling efficient data processing and signal generation.
The device is also equipped with 96 digital I/O terminals, which can be programmed as inputs, outputs, counters/timers, or for custom logic to suit various application needs. This flexibility makes the PXI-7831R an ideal choice for a wide range of digital interfacing tasks.
At its core, the PXI-7831R utilizes a Virtex-II V1000 FPGA with 720 kbits of RAM, providing substantial processing power and memory capacity for complex, real-time signal processing and control applications. It is programmable through the LabVIEW FPGA module, offering a user-friendly environment for developing custom applications.
For those requiring additional signal conditioning or I/O expansion, the PXI-7831R supports interfacing with the NI-9151, further extending its versatility and adaptability to specific project requirements.
