The NI AT-MIO-16XE-50 is a 16-bit multifunction data acquisition board for PC AT series computers, delivering 20 kS/s analog input sampling with 16 single-ended or 8 differential channels. It integrates analog input, analog output, digital I/O, and counter/timer functions on a single ISA card, eliminating jumper configuration through software-managed Plug and Play setup via the DAQ-PnP bus interface chip.
