VKINGING VK702NH-SD 800ksps DAQ LAN Precision High Speed Data Acquisition Card for 8CH Acquisition

Description:

The VK702NH-SD is a 24-bit Ethernet (LAN) data acquisition card. VK702NH-SD features true differential input, 24-bit ADC, 8-channel simultaneous acquisition, maximum 800ksps sampling rate and adjustable pre-gain unit. Data can be stored offline. Using multiple high-precision 24-bit ADC units and input filter units, the data acquisition card features high rate, high resolution, high precision, low noise, high common-mode rejection ratio, wide measurement range, low temperature drift, etc. Thus, it is suitable for various occasions of precision and high-rate acquisition.

It adopts industrial-grade devices, with low temperature drift and strong anti-interference ability. Its shell adopts all-metal shielding, which can adapt to the application of strong industrial interference, and has the advantages of shockproof and anti-interference.
