National Instruments PXIe-6251 Multifunction I/O Module
The NI PXIe-6251 (Part Number: 779777-01) is a member of the M Series by National Instruments. This Multifunction I/O Module is designed with astounding preciseness at a swift sampling rate. The PXIe-6251 requires a cable such as the SHC68-68-EPM 2 m shielded cable and a connector block like the SCB-68A for operation. This module has a 2.8 MS/s maximum update rate, 8 DIO, 24 digital I/O, 16 analog inputs, 16 bits analog input/analog output resolution, 2 analog outputs, and more. This module can be used with the NI-DAQmx and NI-DAQmx Base drivers.
The PXIe 6251 module, along with the other modules in the M Series, can be utilized for test, control, and design applications. When the module is employed for test, it can be utilized with NI signal conditioning for applications, such as component characterization, electronics test, and sensor measurements. When the NI PXIe-6251 is utilized for control applications, the digital lines can be used for pulse-width modulation to control valves, pumps, motors, lamps, and fans. This M Series module can execute numerous control loops at the same time. In addition, with the NI SoftMotion Development Module for LabVIEW, the user can generate a fully customized motion controller with the PXIe-6251. The National Instruments PXIe-6251 Multifunction I/O Module can be used to measure and confirm prototype designs as well. With the use of NI LabVIEW SignalExpress, the user can alter tested and confirmed LabVIEW SignalExpress projects to LabVIEW applications for instantaneous NI PXIe-6251 use. This capability helps tighten the gap between test, control, and design applications.
PXIe-6251 Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
