USB-4718 8-ch Thermocouple Input USB Module with 8-ch Isolated Digital Input
Call for Price
The USB-4700 series consists of true Plug& Play data acquisition devices. No more opening up your computer chassis to install board-just plug in the module, then get the tata. It’s easy and efficient. USB-4718 offers 8 thermocouple inputs with 16-bit resolution, up to 0.1% input range accuracy, or 4 ~ 20 mA inputs.
Reliable and rugged enough for industrial applications, yet inexpensive enough for home projects, the USB-4718 is the perfect way to add measurement and control capability to any USB capable computer. The USB-4718 is fully USB plug and play and easy to use. It obtains all required power from the USB port, so no external power connection is ever required.
