Light and compact devices deliver high-performance I/O for portable USB applications such as field measurements and laptop-based data acquisition.
Two new USB-powered M Series data acquisition (DAQ) devices from National Instruments deliver faster sampling rates and more digital I/O features than previously released bus-powered M Series devices for USB.
The NI USB-6212 and USB-6216 are available with 68-pin SCSI mass termination, screw terminals or 50-pin IDC connectivity to provide multiple connectivity options.
The USB-6212 and USB-6216 enhance the NI USB-621x product offering with a 60% improvement in analogue sampling rates while maintaining high absolute accuracy of 2.7mV at +/-10V and 89uV at +/-200mV.
The devices also provide sixteen 400Ksample/s analogue inputs and two 250Ksample/s analogue outputs, both with 16bit resolution.
These light and compact devices deliver high-performance I/O for portable USB applications such as field measurements and laptop-based data acquisition.
The new devices also feature improved digital I/O by providing more channels, 32bit counters and 32 bidirectional digital lines for screw-terminated devices or 24 bidirectional digital lines for 68-pin devices.
The USB-6212 and USB-6216 mass terminated devices deliver 68-pin cabled connectivity to terminal blocks and custom accessories while 50-pin IDC connectors on OEM devices offers easy board mating for integration in embedded systems.
Additionally, the USB-6216 provides optional 60V CAT I isolation for protection against transient voltages, improved noise immunity and ground-loop removal.
The USB-6212 and USB-6216 are shipped with NI-DAQmx driver software and NI LabView SignalExpress LE, a limited-feature version of the interactive measurement software for quickly acquiring, analysing and presenting data with no programming required.
The NI-DAQmx driver delivers time-saving features such as code generation for both LabView and text-based languages; 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.
These devices are fully RoHS-compliant, demonstrating the NI commitment to eliminating certain hazardous substances from products to benefit the environment.
