The Measurement Computing PCI-DAS1001 is a multifunction analog and digital I/O card for PCI bus systems, delivering 12-bit analog acquisition and output with software-configurable input modes, 24 bits of parallel digital I/O, and three 16-bit counters. Plug-and-play operation eliminates manual configuration; all hardware settings are managed through software. The board connects via a 100-pin high-density Robinson Nugent connector and draws power directly from the PCI bus.
