  • Support the PCI Express x1
  • 32 Optically-isolated Digital Input Channels
  • 32 Optically-isolated Digital Output Channels(Source, PNP)
  • Built-in DC/DC converter with 3000 VDC isolation
  • Card ID function (SMD Switch)

The PEX-P32A32 supports PCI Express bus. These cards provide 32 optically-isolated Digital Input channels and 32 optically-isolated Digital Output channels, arranged into four isolated banks. Each Digital Output channel includes a PNP transistor and an integral suppression diode for the inductive load. Isolated input channels 0-15 are allocated to Group A, while channels 16-31 are allocated to Group B. Isolated output channels are allocated to Groups C and D. The photocoupler input for the PISO-P32A32U-5V can be powered by either an internal current source or an external power supply, while the input for the PEX-P32A32 operates using an external power supply only.

The PEX-P32A32 also include an onboard Card ID switch that enables the board to be recognized via software if two or more boards in the same 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.
