The NI PCI-6071E is a multifunction data acquisition board for PCI bus computers, integrating analog input/output, digital I/O, and counter/timer functions into a single E Series platform. It delivers 1.25 MS/s sampling across 64 single-ended or 32 differential analog input channels with 12-bit resolution, supporting 15 software-selectable input ranges. The board combines 2 analog output channels, 8 digital I/O lines, and dual 24-bit counters/timers with 50 ns timing resolution to address industrial automation, laboratory automation, research, and manufacturing test requirements.
