产品描述
The USB-4700 series consists of
true Plug & Play data acquisition
devices. No more opening up your
computer chassis to install boardsjust
plug in the module, then get
the data.
It’s easy and efficient. Models
USB-4751 (48-bit) and
USB-4751L (24-bit) are digital
I/O data acquisition modules for the
USB bus. The 48/24 bits are divided
into six/three 8-bit I/O ports, and
users can configure each port as
input or output via software. The
USB-4751 and USB-4751L
also provide one event counter and
three 16-bit timers, which can be
cascaded to become a 32-bit timer.
Data collection is simple. Simply
plug the data acquisition module
into an available USB port and our
easy-to-use Windows software
does the rest. The software
converts your PC into a real-time
strip chart recorder. Data can be
printed in graphical or tabular
format. It can also be exported to
a text or Microsoft Excel file.
