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-4751 is a 48-bit digital IO module with USB interface. Its 48 bits are divided into six 8-bit IO ports and users can configure each port as input or output via software. USB-4751 also provides one event counter and three 16-bit timers, which can be cascaded to become a 32-bit timer.
