The PCI-P16C16 is a 5 V PCI card that support “Plug & Play” functionality to automatically obtain I/O resources from the BIOS. This card contains 16 optically isolated digital input channels and 16 open collector (sink, NPN) digital output channels. The DI channels provide 5000 Vrms isolation protection that allows the input signals to be completely floated so as to prevent ground loops and isolate the host computer from damaging voltages. The open collector output (DO) channels are typically used for alarm and warning notification, control of signal output, control of external circuits that require a higher voltage level, and signal transmission applications, etc. The PCI-P16C16 contains a single DB-37 connector and a single 40-pin box header and includes a 40-pin to DB-37 flat cable for easy wiring.

The PCI-P16C16 supports various OS versions, such as Linux, DOS, Windows 98/NT/2000 and 32/64-bit Windows 7/Vista/XP. DLL and Active X control together with various language sample programs 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 quickly and easily develop their own applications.
