Description
The National Instruments PCIe-6251, part number 779512-01, is a high-performance DAQ board from the M Series, capable of handling 16 single-ended or 8 differential analog input channels with a 16-bit resolution. It delivers a maximum sample rate of 1.25 MS/s for single channels and 1.00 MS/s for multiple channels. The board also features 2 analog output channels with a maximum update rate of 2.86 MS/s for one channel and 2.00 MS/s for two channels, both with a 16-bit DAC resolution.
In addition, there are 24 digital I/O lines and 8 correlated DIO lines available for various digital interfacing needs. The PCIe-6251 is designed for use with NI-DAQmx, NI-DAQmx Base, and Measurement Hardware DDK driver software, providing high compatibility with a range of development environments while being incompatible with the Traditional Legacy NI-DAQ driver.
The board leverages the PCI Express interface, ensuring high-speed data transfers with a bandwidth of 250 MB/s per direction. For maintaining accuracy and performance, a regular calibration interval is recommended, ensuring that the PCIe-6251 continues to deliver reliable data acquisition for sophisticated applications.
