产品介绍：The PISO-P16R16U is a universal PCI card supporting both the 5 V and 3.3 V PCI bus, while the PEX-P16R16i/PEX-P8R8i is a PCI Express card. Each contain 8 or 16 photo coupler digital inputs that provide 3750 Vrms isolation protection, allowing the input signals to be completely floated so as to prevent ground loops. They are also equipped with 8 or 16 relay output channels to enable the control of the ON/OFF state of external devices, drive external relays or small power switches, or activate alarms, etc. The PISO-P16R16U/PEX-P16R16i is fully compatible with the PISO-P16R16, and users can easily replace the PISO-P16R16 with the PISO-P16R16U/PEX-P16R16i without any need for software/driver modification when using PCI Express computers.Note: The product name for the PISO-P16R16E (PCI Express) card has been amended to the PEX-P16R16i (all features remain the same). The prefix "PEX" indicates the card is based on the "PCI Express interface".These cards support 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.
