The National Instruments PXI-6233 is an isolated M Series multifunction data acquisition (DAQ) board. It combines the safety and performance benefits of isolation with high-performance timing, amplification, and calibration technologies to offer accurate measurements and precise control.

Isolation provides:
1. Safety from transients
2. Noise rejection
3. Reduced ground loops
4. Common-mode voltage rejection

The PXI-6233 is ideal for test, measurement, control, and design applications in environments with high voltages and electrical noise. You can use the PXI-6233 to read from encoders, flow meters, and proximity sensors as well as control valves, pumps, and relays.

The isolated M Series family of devices incorporates advanced M Series technologies including the NI-STC 2 system controller, NI-PGIA 2 programmable instrumentation amplifier, and NI-MCal calibration technology to increase performance and accuracy. To learn more about M Series technologies, 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 and download driver software. M Series devices are not compatible with the Traditional NI-DAQ (Legacy) driver.

Application Software
With NI LabVIEW, you can create custom DAQ applications with the ease of graphical programming and power of more than 500 analysis functions. LabVIEW Full and Professional Development Systems include LabVIEW SignalExpress for interactive data logging. M Series DAQ 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; LabVIEW SignalExpress 1.x; or LabVIEW with the LabVIEW Real-Time Module 7.1. M Series DAQ devices are also compatible with Visual Studio .NET, C/C++, and Visual Basic 6.
