USB Data Acquisition Devices from National Instruments features 80 I/O Channels and BNC Connectivity

The 80-channel USB M Series devices are the industry’s highest channel-count USB multifunction data acquisition devices, the BNC USB M Series devices provide direct BNC connectivity and the USB C Series modules offer less expensive and more portable hardware. With the plug-and-play connectivity of USB, engineers and scientists have an easy-to-use, portable solution for their measurement, monitoring and control applications.



Using the 80-channel USB M Series devices, engineers can collect more data with less equipment because the devices provide high-channel-count application solutions in a single device. The NI USB-6225 and USB-6255 offer 80 channels for analogue inputs and up to 1.25 MS/s (750 kS/s aggregate) sampling rates per channel. The devices feature NI signal streaming and provide up to 48 digital input/output lines and two counter/timers. Engineers can choose either integrated connectivity or mass termination to connect to the devices. Mass termination provides access to NI signal conditioning platforms or to custom boards.



NI USB-6221, USB-6229, USB-6251 and USB-6259 BNC USB M Series devices include the standard M Series features along with direct BNC connectivity that provides up to 16 differential analogue inputs, four analogue outputs, eight digital I/O BNC connectors and up to 60 screw terminals. The BNC USB M Series features BNC connectivity directly on the USB device, eliminating the need for an extra cabled accessory to house BNC connections. BNC delivers easy and durable connectivity while achieving better noise rejection in a rugged, portable device ideal for benchtop, academic and field use. NI BNC devices have up to 1.25 MS/s (750 kS/s aggregate) sampling rates per channel, support NI signal streaming technology, provide up to 48 digital I/O lines and feature two counter/timers.



NI M Series technologies, including the NI-STC 2 system controller, NI-PGIA 2 amplifier and NI-MCal calibration, provide more performance, more accuracy and more I/O than other data acquisition devices. The new USB M Series devices combine M Series performance with Hi-Speed USB ease of use to handle a wide range of applications including automated test, process control and sensor measurements. All M Series devices support NI signal streaming technology, making it possible to acquire and generate multiple analogue and digital I/O signals simultaneously.



The USB-9237, based on the NI C Series platform, offers high-speed performance in a compact form factor for low-channel-count applications including strain, load, pressure and other bridge-based measurements. The bus-powered module removes the need for an external power supply and offers NIST-traceable calibration; 24-bit resolution; direct connectivity; 50 kS/s simultaneously sampled analogue inputs; quarter-, half- and full-bridge completion; up to 10 V internal excitation; and transducer electronic data sheet (TEDS) smart sensor compatibility.



Engineers can easily acquire data from these NI USB devices with the included NI-DAQmx driver software and NI LabVIEW SignalExpress LE, an interactive measurement software for quickly acquiring, analysing and presenting data. NI-DAQmx software offers time-saving features such as code generation; more than 3,000 measurement examples; device simulation; connection diagrams; and compatibility with LabVIEW, ANSI C/C++, C#, Visual Basic .NET and Visual Basic 6.0.



Engineers can use all of these devices with NI software, including LabVIEW, LabVIEW SignalExpress, Measurement Studio and LabWindows™/CVI and hardware such as PXI modules from NI.
