The PISO-P32A32U universal PCI card supports 3.3 V/5 V PCI bus. These cards provide 32 optically-isolated DI channels and 32 optically-isolated DO channels, arranged into four isolated banks. Each DO 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 can be powered by either an internal current source or an external power supply, while the input for the PISO-P32A32U operates using an external power supply only.

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-P32A32-5V can be powered by using either an internal current source or an external power supply, while the input for the PISO-P32A32U operates using an external power supply only.

The PISO-P32A32U 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.
