View Data Sheet and Specifications

The NI USB-6218 is a bus-powered isolated USB M Series multifunction data acquisition (DAQ) module optimized for superior accuracy at fast sampling rates. It offers 32 analog inputs; 250 kS/s single-channel sampling rate; two analog outputs; eight digital input lines; eight digital output lines; four programmable input ranges (±0.2 to ±10 V) per channel; digital triggering; and two counter/timers. For improved accuracy and safety, 60 V, CAT I isolation is provided.

The USB-6218 is designed specifically for mobile or space-constrained applications. Plug-and-play installation minimizes configuration and setup time, while direct screw-terminal connectivity keeps costs down and simplifies signal connections. Because this module is bus-powered from USB, you can discard unnecessary external power supplies.

The USB-6218 also features NI signal streaming technology, which gives you DMA-like bidirectional high-speed streaming of data across USB. For more information about NI signal streaming, view the Resources tab.

Driver Software
NI-DAQmx driver and measurement services software provides easy-to-use configuration and programming interfaces with features such as the DAQ Assistant to help reduce development time. 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 LabVIEW SignalExpress LE data-logging software so you can quickly acquire, analyze, and present data without programming. In addition to LabVIEW 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, ANSI C/C++, and Visual Basic 6.0.
