The National Instruments DAQCard-1200 is a 12-bit multifunction I/O card for portable data acquisition via PCMCIA Type II interface. It combines analog input/output, digital I/O, and timer/counter functionality in a compact form factor, delivering up to 100 kS/s sampling and ±0.5 LSB typical accuracy. Designed for measurement and control applications requiring power efficiency and mobility, it integrates with Windows-based systems and LabVIEW development environments.
