The NI DAQCard-AI-16XE-50 is a 16-channel analog input card built for portable and embedded measurement systems. Operating at 200 kS/s with 16-bit resolution, it delivers accurate data acquisition across multiple signal levels through software-programmable input ranges and gains. This PCMCIA-based multifunction DAQ integrates analog I/O, digital I/O, and counter/timer functionality in a compact E Series form factor.
