VK7018 Ethernet/USB 8-channel 24-bit data acquisition card

VK7018 Ethernet/USB 8-channel 24-bit data acquisition card

    VK7018 is an Ethernet/USB high-speed data acquisition card with 8-channel true differential input, 24-bit resolution, single channel maximum sampling rate of 256Ksps, 8-channel synchronization, a total of 2.048Msps, precision pre gain amplification, Gigabit Ethernet transmission unit, and integrated IEPE/ICP hardware support features. This product uses multiple high-precision 24-bit ADC units and a front-end differential amplifier module developed in cooperation with our company's accumulation over the years, making it suitable for various occasions of precision high-speed acquisition due to its advantages of high speed, high resolution, high accuracy, ultra-low noise, high rejection ratio, wide measurement range, and low temperature drift.

Applications

*Weak signal measurement collection              *Low noise data collection
*Ethernet networking measurement system     *High-impedance differential signal measurement

IEPE mode description
    This acquisition card integrates IEPE/ICP hardware function support.
    The acquisition card is internally integrated with a 24V power supply unit, a constant current drive, and a receiving unit, and each channel can be individually switched to the commonly used "Analog input mode" or "IEPE mode" through software settings.
    In IEPE mode, the output is 24V 4mA (compatible with 2mA), and the ADC input is in an AC coupled input state. Eight channels can be independently switched and controlled. Differential input connection can further reduce transmission interference.

Input port connects to IEPE sensor

    For IEPE sensors, AGND serves as the negative end of the input, and AIN+ serves as the positive end of the input
* Set the corresponding input to IEPE MODE on the software.

Collection card software description

    The VK7018 USB data acquisition card can work in common operating systems such as WIN11/Win10/WIN7, LINUX, and provides a dynamic link library called by common programming languages such as Python, VB, VC, C #, C++Builder, VB, Delphi, Labview/Labwindows, and Matlab. The programming function interface is simple and easy to use, and it is easy to write applications. It provides routines such as Python, VB, VC, C#, C++Builder, VB, Delphi, Labview/Labwindows, and Matlab.
