Description
The NI USB-7846R Multifunction Reconfigurable I/O Device, part of the R Series and manufactured by National Instruments, is designed to be used with USB 2.0 connectivity and is configured via the LabVIEW FPGA application tool. It boasts a small signal bandwidth of 1 MHz and a large signal bandwidth of 500 kHz. The device is built around a powerful Kintex-7 160T FPGA, allowing for extensive customization and performance tuning.
With 48 bidirectional digital channels, users can handle a wide array of digital signals, and the 500 kS/s sampling rate ensures accurate and timely data acquisition. The device operates at a clock frequency rate of 80 MHz, providing the responsiveness needed for demanding applications. Additionally, the USB-7846R offers 16 analog channels, with 8 dedicated to inputs and 8 to outputs, all benefiting from analog DC input/output coupling.
The inclusion of 3 DMA channels facilitates efficient data transfers, minimizing CPU usage and enhancing system performance. Designed for flexibility, the device supports an input voltage range of 9-30 V and is equipped with overvoltage protection to safeguard against unexpected power spikes. This makes the NI USB-7846R a robust and reliable solution for a broad range of measurement and control tasks.
