PCI Express Basic (250 to 500 kS/s, 16-Bit)

Optimized for cost-sensitive applications, these low-cost NI multifunction data acquisition (DAQ) boards for the PCI Express bus are ideal for adding general-purpose I/O to desktop computers.

With guaranteed measurement accuracy at a low price, NI multifunction DAQ devices are used in a wide variety of applications, including laboratory automation, scientific research, design validation, manufacturing test, and embedded OEM applications. To learn more about absolute accuracy specifications, refer to the Specifications tab on individual product pages.

High-Throughput PCI Express Bus
PCI Express offers dedicated bandwidth of up to 250 MB/s in each direction to each device, and NI X Series devices feature a native PCI Express interface with optimizations for high throughput and low latency. For high-channel-count applications, consider PXI Express to synchronize multiple devices and achieve system expandability with the PXI platform.

Data Acquisition Software
Working with easy-to-use driver software featuring an intuitive application programming interface makes a big impact on completing a project on time and under budget. These NI data acquisition boards are shipped with NI-DAQmx multithreaded driver software that provides ease of use, flexibility, and high performance on multiple programming platforms, including NI LabVIEW and LabWindows™/CVI, ANSI C/C++, and Microsoft Visual Studio .NET. NI-DAQmx features free LabVIEW SignalExpress LE data-logging software and hundreds of shipping examples to help you get started quickly with your application.
