The Measurement Computing PCI-DAS1602/16 is a 16-bit multifunction PCI card engineered for precision data acquisition in scientific and industrial measurement applications. This full-sized PCI board integrates analog input, analog output, digital I/O, and counter/timer functionality in a single plug-and-play solution. All configuration is software-managed, eliminating manual jumper or switch settings and enabling rapid deployment in diverse control and measurement tasks.
