The PISO-P32A32U card is a new generation product that ICP DAS provides to meet RoHS compliance and the new PISO-P32A32U card is designed as a drop-in replacement for the PISO-P32A32. Therefore, there is no any software modification needed while users upgrade the systems from PISO-P32A32 to PISO-P32A32U.

The PISO-P32A32U supports 3.3 V/5 V PCI Bus and provides 32-channel Optically Isolated Digital Input and 32-channel Optically Isolated Digital Open-collector output that are arranged into four isolated banks. Each input channel adopts a photo-coupler input which allows either internal isolated power supply or external power selected by jumper. Each digital output channel contains PNP transistor and integral suppression diode for the inductive load. The power supply of the input port may use the external power or the power from the PC side by using a DC/DC converter. The power supply of the output port requires the external power source. The PISO-P32A32U eliminates ground-loop problems and provides isolation that protects host computer from damaging voltages.

The PISO-P32A32U also adds a Card ID switch. Users can set Card ID on a board and recognize the board by the ID via software when using two or more PISO-P32C32U cards in one computer.

The PISO-P32A32U supports various OS such as Linux, DOS, Windows 98, Windows 2000, Windows NT and Windows XP/2003/Vista/2008/7 32/64-Bit. It also provides the DLL and Active X control, and various language sample programs of Turbo C++, Borland C++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, Visual C#.NET, Visual Basic.NET and LabVIEW to help users to quickly and easily develop their applications.
