Description
The NI USB-7856R Multifunction Reconfigurable I/O Device, manufactured by National Instruments, is offered with two distinct part numbers, 782916-01 which is enclosed, and 782916-02 which is not, providing versatility for various application needs. This device boasts 8 analog input/output channels with a high-resolution 16-bit analog to digital converter, ensuring precise measurements and control.
With a maximum sampling rate of 1 MS/s per channel, the USB-7856R is well-suited for high-speed data acquisition. Its extensive digital I/O capabilities include 48 channels, with 32 channels capable of operating up to 80 MHz and an additional 16 channels capable of up to 10 MHz, allowing for robust digital communication and control.
At its core, the USB-7856R is powered by a Kintex-7 160T FPGA which includes 600 DSP48 slices, 101,400 LUTs, 202,800 flip-flops, and 11,700 kbit/s BRAM, enabling complex, user-defined processing and logic implementation. Data transfer is efficient and flexible, offering both programmed I/O and DMA across 3 dedicated DMA channels.
The device operates with a power consumption of 20 W and requires an input voltage ranging from 9 V to 30 V, with overvoltage protection up to 40 V at the input voltage terminal. This ensures a robust operation even in fluctuating power environments. The USB-7856R is designed to handle a maximum working voltage of ±12 V between a channel and earth, making it a reliable choice for a wide array of industrial and research applications.
