Advantech USB-4751L-AE 24-CH TTL DIO USB Module
Dove Code: AQ2005L |
Manufacturer: USB-4751L-AE


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 and efficient. USB-4751L is a 24-bit digital I/O module for the USB bus. Its 24 bits are divided into three 8-bit I/O ports and users can configure each port as input or output via software. USB-4751L also provides one event counter and three 16-bit timers, which can be cascaded to become a 32-bit timer.
