VK7015 Ethernet/USB16 channel 24 bit Data Acquisition Card

VK7015 is an Ethernet/USB compatible high-speed data acquisition card. It features 16-channel input, 24-bit resolution, a single channel maximum sampling rate of 32 ksps, a total of 512 ksps for 16-channel synchronization, precise pre gain amplification, and integrated IEPE/ICP hardware. This product uses multiple high-precision 24-bit ADC units and preamplifier modules that have been developed in cooperation with our company for many years, making it characterized by high speed, high resolution, high accuracy, ultra-low noise, high rejection ratio, wide measurement range, and low temperature drift. It is suitable for various occasions of precision high-speed acquisition.
All components of the VK7015 acquisition card are of industrial grade and adopt all-metal shielding, which can adapt to applications with strong industrial interference, and has the advantages of moisture resistance, shock resistance, and anti-interference.

Description of the IEPE mode
This acquisition card can be optionally equipped with IEPE/ICP hardware functions.
The collector card is internally equipped 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 hardware jumper settings.
In IEPE mode, the output is 24V 4mA (compatible with 2mA).
16 channels can be independently configured.
