NI PXI-6221

16-Bit, 250 kS/s, 16 Analog Inputs

  • Two 16-bit analog outputs (833 kS/s)
  • 24 digital I/O; 32-bit counters; digital triggering
  • NIST-traceable calibration certificate and more than 70 signal conditioning options
  • Correlated DIO (8 clocked lines, 1 MHz)
  • Select high-speed M Series for 5X faster sampling rates or high-accuracy M Series for 4X resolution.
  • NI-DAQmx driver software and NI LabVIEW SignalExpress LE interactive data-logging software

The National Instruments PXI-6221 is a low-cost multifunction M Series data acquisition (DAQ) board optimized for cost-sensitive applications. Also consider the high-speed M Series devices for 5X faster sampling rates or the high-accuracy M Series devices for 4X resolution and superior measurement accuracy.

Low-cost M Series devices incorporate advanced features such as the NI-STC 2 system controller, NI-PGIA 2 programmable amplifier, and NI-MCal calibration technology to increase performance and accuracy. To learn more about M Series technologies, device specifications, and information on recommended cables and accessories, please refer to the data sheet and specifications.

Driver Software
M Series devices work with multiple operating systems using three driver software options including NI-DAQmx, NI-DAQmx Base, and the Measurement Hardware DDK. 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 data acquisition device includes a copy of NI LabVIEW SignalExpress so you can quickly acquire, analyze, and present data without programming. In addition to LabVIEW SignalExpress, M Series data acquisition devices are compatible with the following versions (or later) of NI application software – LabVIEW 7.x, LabWindows™/CVI 7.x, or Measurement Studio 7.x; or LabVIEW with the LabVIEW Real-Time Module 7.1. M Series data acquisition devices are also compatible with Visual Studio .NET, C/C++, and Visual Basic 6.
