Digital I/O Terminal for USB2.0

DIO-0808TY-USB

* Specifications, color and design of the products are subject to

change without notice.

This product is a USB2.0-compatible terminal that expands the

input or output function of a PC for digital signals. Being

bus-powered, it does not need an external power supply.

DIO-0808TY-USB has the 8ch of unisolated TTL level input and

8ch of unisolated open-collector output. In addition, it uses a

protection circuit (surge protection) as its I/O circuit as well as

an easily-wired terminal connector.

Windows driver is bundled with this product.

Using the dedicated library VI-DAQ makes it possible to create

each application for LabVIEW.

Unisolated TTL level input, unisolated open-collector

output

DIO-0808TY-USB has the 8ch of unisolated TTL level input

whose response speed is 200nsec and 8ch of unisolated

open-collector output. The output rating is max. 28VDC,

40mA per ch.

Compatible to USB1.1/USB2.0 and not necessary to power

this product externally as the bus power supply is used.

Compatible to USB1.1/USB2.0 and capable to achieve high

speed transfer at High Speed (480 Mbps). Not necessary to

power supply this product externally as the bus power of USB

is used.

Surge absorption diodes are built in the I/O circuit for

surge voltage protection.

DIO-0808TY-USB has a surge absorption diode connected to

the +5V output pin at each I/O point to protect against surge

voltages.

Windows compatible driver libraries are attached.

Using the attached driver library API-USBP(WDM) makes it

possible to create applications of Windows. In addition, a

diagnostic program by which the operations of hardware can

be checked is provided.

Terminal connector facilitating wiring

Wiring is easy as the terminal connector (screw type) is used.

LabVIEW is supported by a plug-in of dedicated library

VI-DAQ.

Using the dedicated library VI-DAQ makes it possible to make

a LabVIEW application.
