  • Supports PCI Express x1
  • Card ID Function(SMD Switch)
  • Digital Output status readback
  • 64 optically isolated DO (open collector) channels
  • Four isolated banks when using four isolated external power supplies
  • 3750 Vrms photo-isolation protection



The PEX-C64 supports PCI Express bus. These cards provide 64 optically isolated digital output (DO) channels, each of which includes a darlington transistor that provides 3750 Vrms isolation, and an integrated suppression diode for inductive load. These DO channels are allocated into four isolated banks when using four isolated external power supplies. These DO channels act as an interface to field logic signals, eliminate ground-loop problems, and isolate the host computer from damaging voltages. These cards contains has a single DB-37 connector and a single 40-pin male header, each of which contains 32 output channels.

The PEX-C64 also adds a Card ID switch on-board. Users can set Card ID and then recognize the board by the ID via software when using two or more PEX-C64 cards in one computer.

The cards support various OS versions, such as Linux, DOS, Windows. DLL and Active X control together with various language sample program based on Turbo C++, Borland C++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual Basic.NET and LabVIEW are provided in order to help users to quickly and easily develop their own applications.
