This product is a USB2.0-compatible terminal that expands the input function of a PC for digital signals.Being bus-powered, it does not need an external power supply. It has the 16ch of unisolated TTL level input. In addition, it uses a protection circuit (surge protection) as its Input circuit as well as an easily-wired terminal connector. Windows driver is provided for this product.

Unisolated TTL level input
It has the 16ch of unisolated TTL level input whose response speed is 200nsec.

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 HighSpeed (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 input circuit for surge voltage protection.
DI-16TY-USB has a surge absorption diode connected to the +5V output pin at each input point to protect against surge voltages.

Windows compatible driver libraries are provided.
Using the attached driver library API-DIO(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.
