The USB-4761 is a relay actuator
and isolated D/I module for USB
bus. It provides 8 optically-isolated
digital inputs with isolation
protection of 2500 Vdc for collecting
digital inputs in noisy environments
and 8 relay actuators for serving
as on/off control devices or
small power switches. For easy
monitoring, each relay is equipped
with one red LED to show its
on/off status.
The USB-4761s 8 optically-isolated
digital input channels are ideal for
digital input in noisy environments
or with floating potentials.
Rugged Protection
The USB-4761 digital input
channels feature a rugged isolation
protection for industrial, lab and
machinery automation applications.
It durably withstands voltage up to
2500 Vdc, protecting your host
system from any incidental harms.
If connected to an external input
source with surge-protection, the
USB-4761 can offer up to a
maximum of 2000 Vdc ESD
(Electrostatic Discharge) protection.
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.
