Contec DO-32(USB) - Opto-isolated Digital Output Module for USB2.0

32 Channels of Opto-isolated Open Collector Digital Outputs


Contec's DO-32(USB) is a USB 2.0 compliant module that extends the digital signal output functions of a PC. DO-32(USB) has 32 opto-isolated output channels for 12 - 24VDC operation. Using expansion modules, the number of output channels can be extended up to 128 lines. In addition, this product can be directly attached onto 35-mm DIN rails for embedded applications. Windows driver is bundled. A Labview library is also available.

  • The output section is a high sink current, open collector type using high-capacitance transistors. 150 mA/24 VDC or 50 mA/48 VDC max. (per channel).
  • Screwless connector plug allows you to easily attach and detach wires without using any special tools.
  • Easy to extend number of I/O channels using an expansion module: Adding optional modules (up to 3 units) can easily increase the number of I/O channels. The unique structure for connection by stacking enables easy and compact system configuration.
  • The design that is convenient to embedded: On the attachment which a 35mmDIN rail can install directly, it can be attached and detached easily.
  • Easy-to-develop application: Visual Basic, Visual C++, Delphi and C++ Builder sample programs and utility software are bundled.
