The Industrial Computer PCI DAS1601/1602 is a PCI-bus data acquisition and control card engineered for industrial measurement and process monitoring. It integrates analog input/output, digital I/O, and on-board FIFO buffering to support high-speed data capture and real-time control in demanding environments. Compatible with Windows and Linux operating systems, the card delivers flexible channel configurations and selectable gain/range settings for diverse measurement scenarios.
