The Measurement Computing / IOtech DaqBoard/3005 is a 16-bit, 1 MHz multifunction data acquisition board for PCI bus computers. It integrates analog inputs, analog outputs, digital I/O, and counter/timer functions with deterministic timing across all signal types. The board supports simultaneous and synchronous operation, making it suitable for industrial automation, scientific experimentation, and manufacturing test applications requiring precise measurement and control with minimal latency.
