Contec DIO-1616HN-USB - Opto-Isolated Digital I/O Module for USB2.0

16 Opto-Isolated Inputs, 16 Channels of Opto-Isolated (5 - 50VDC) Level Digital I/O


Contec's DIO-1616HN-USB is a USB2.0-compliant digital I/O unit that provides digital input /output function to a PC via USB port. The unit's compact design (188.0(W) x 78.0(D) x 30.5(H)) makes it easy to install the within a electrical panel or device using DIN rail mounting jigs, or on the floor or wall. This product is compatible with digital input and output signals at 5 - 50VDC which features 16 channels of opto-coupler isolated inputs (compatible with current sink output) and 16 channels of opto-coupler isolated open-collector outputs(compatible with current sink type), equipped with output transistor protection circuit (surge voltage protection and over current protection). A Windows driver and LabVIEW library are available.

  • Installation on the floor / wall /ceiling is possible by screw fastening, magnet, rubber feet, etc. In addition, DIN rail mounting mechanism is equipped as standard with the product, making it easy to install the product within the panel or the device.
  • Compact design of 188.0(W) x 78.0(D) x 30.5(H) does not require special installation location.
  • Adoption of terminal connector (with screws) enables to achieve easy wiring.
  • This product has 16 channels of optocoupler isolated inputs, compatible with current sink output of of 5 - 50 VDC whose response speed is 200µsec. 16 channels share one common. As the power to run the opto-couplers is supplied internally, no external power supply is required.
  • This product has 16 channels of opto-coupler isolated open-collector outputs (current sink type) whose response speed is 200µsec, supporting driver voltages of 5- 50 VDC for I/O. The output rating is max.100mA per channel. Common terminal provided per 8 channels, capable of supporting a different external power supply.
  • As the USB I/F on PC is isolated from the input and output interfaces by opto-couplers, this product has excellent noise performance.
  • Using the attached digital I/O driver 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.
  • Using the dedicated library VI-DAQ makes it possible to make a LabVIEW application.
