Introduction
The USB-4700 series consists of true plug & play data acquisition devices. No more opening up your computer chassis to install boards just plug in the module, then get the data.
It’s easy to use and efficient. USB-4718 offers 8 thermocouple inputs with 16-bit resolution, up to 0.1% input range accuracy. Portable design makes the USB-4718 suitable for field
research. Also, the input channels can be set separately making handling multiple type of sensors with just one USB-4718 module possible.
Reliable and rugged enough for industrial applications, yet affordable for home projects, the USB-4718 is the perfect way to add measurement and control capability to any USB
capable computer. The USB-4700 series is fully plug and play and easy to use. It obtains all required power from the USB port, so no external power connection is ever required.
