The NI USB-6251 BNC is a USB high-performance M Series multifunction DAQ module optimized for superior accuracy at fast sampling rates. It is ideal for applications such as data logging and benchtop sensor measurements. It provides 8 analog input, 2 analog output, 8 digital I/O, 1 APFI, and 2 user-defined BNC terminals.

The USB-6251 BNC is designed specifically for mobile or space-constrained applications. Plug-and-play installation minimizes configuration and setup time, while direct screw-terminal connectivity helps keep costs down and simplifies signal connections.

This module also features new NI Signal Streaming technology, which allows for DMA-like bidirectional high-speed streaming of data across the USB bus. For more information about NI Signal Streaming, see the Resources tab.

Each module also features an OEM version. See the Resources tab or use the left navigation to get pricing and technical information. Certified power supply included.

Driver Software
NI-DAQmx driver and measurement services software provides easy-to-use configuration and programming interfaces with features such as DAQ Assistant to help reduce development time. Browse the information in the Resources tab to learn more about driver software or download a driver. M Series devices are not compatible with the Traditional NI-DAQ (Legacy) driver.

Application Software
Every M Series DAQ device includes a copy of NI SignalExpress LE so you can quickly acquire, analyze, and present data without programming. In addition to SignalExpress, M Series DAQ devices are compatible with the following versions (or later) of NI application software: LabVIEW 7.1, LabWindows™/CVI 7.x, or Measurement Studio 7.x. M Series DAQ devices are also compatible with Visual Studio .NET, C/C++, and Visual Basic 6.0.
