Contec DI-16TY-USB - Digital Input Terminal for USB2.0

16 Channels of Unisolated TTL Level Digital I/O


Contec's DI-16TY-USB 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 16 channels of unisolated TTL level inputs. In addition, it uses a protection circuit (surge protection) as its Input circuit and uses a standard terminal connector, which allows easy wiring. Windows driver is bundled with this product. A Labview library is also available.

  • It has the 16ch of unisolated TTL level input whose response speed is 200nsec.
  • 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.
  • DI-16TY-USB has a surge absorption diode connected to the +5V output pin at each input point to protect against surge voltages.
  • 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.
  • Wiring is easy as the terminal connector (screw type) is used.
