The National Instruments PCI-MIO-16XE-50 (also designated PCI-6011E) is a 16-bit multifunction DAQ board delivering 20 kS/s analog input sampling on a PCI bus platform. This card integrates analog input, analog output, digital I/O, and counter/timer functionality in a single 68-pin SCSI-II connector interface, making it suitable for control systems, high-speed data logging, and sensor signal measurement.
