Contec DIO-0808TY-USB - Digital I/O Terminal for USB2.0

Eight Channel Unisolated Inputs, Eight Channel Unisolated Outputs


Contec's DIO-0808TY-USB is a USB 2.0-compatible digital I/O terminal, which can be connected to a USB interface of a PC to input and output digital signals (max 28 VDC) easily. Input up to eight channels (unisolated TTL level) and also output up to eight channels (unisolated open-collector output). Using bundled driver library [API-USBP(WDM)], you can create Windows application software for this terminal in your favorite programming language supporting Win32 API functions, such as Visual Basic or Visual C++. A LabVIEW library is also available.

  • It 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 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.
  • DIO-0808TY-USB has a surge absorption diode connected to the +5V output pin at each I/O 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.
