Description
The product with part number 190996D-03L / 779070-01 falls under the category of PC-based Multifunction DAQ and is identified by the model PCI-6251. This model, the NI PCI-6251, is characterized by its impressive capabilities, including 16 AI (Analog Input), 24 DIO (Digital Input/Output), and 2 AO (Analog Output) channels.
It boasts a 16-bit resolution, ensuring precise data acquisition and signal processing. The maximum sampling rate can reach up to 1.25 MS/s (million samples per second) for single-channel operations and 1 MS/s for multi-channel operations, allowing for efficient data collection from multiple sources simultaneously.
The device supports 16 single-ended or 8 differential analog input channels, providing flexibility in connecting a variety of sensors and signals. Additionally, it features 2 analog output channels for generating signals or outputting data. The 24 bi-directional digital I/O channels enhance the device’s versatility in interfacing with other digital devices or systems.
Compatible driver software options include NI-DAQmx Base, Measurement Hardware DDK, and NI-DAQmx, ensuring seamless integration and ease of use with a variety of software environments. The PCI-6251 is supported by several Application Development Environments (ADEs) such as LabVIEW, LabWindows/CVI, Measurement Studio, and Microsoft Visual Studio, offering a wide range of development possibilities for users.
This DAQ device is compatible with signal conditioning equipment such as NI SCXI and SCC, allowing for the enhancement of signal quality or the adaptation of signals for specific measurement needs. The digital line drive capability of 24 mA and a digital line clocking speed of up to 10 MHz enable high-speed digital communications. Lastly, it is equipped with 6 DMA (Direct Memory Access) channels, facilitating the rapid transfer of data to and from the device without burdening the host computer’s CPU.
