PEX-P64 PCI Express, 64-ch Isolated DI Board


Key Features

  • Support PCI Express x1
  • Card ID Function(SMD Switch)
  • 64-channel Isolated DI
  • Built-in DC/DC converter providing 3000 VDC isolation
  • Four isolated banks when using four isolated external power supplies
  • 3750 Vrms photo-isolation protection
  • Selectable internal or external power for DI


The ICP DAS PEX-64 board utilizes the PCI Express bus and provides 64 optically-isolated Digital Input channels that use either an internal or external power supply that can be selected via a jumper. The internal power is provided by an onboard isolated DC/DC converter that provides 3000 VDC isolation and is used for connecting dry-contact input devices. The DI channels are arranged into four isolated banks when using four isolated external power supplies, where DI channels 0 to 15 are allocated to bank A, DI channels 16 to 31 are allocated to bank B, DI channels 32 to 47 are allocated to bank C, and DI channels 48 to 63 are allocated to bank D. The onboard photocouplers provide 3750 Vrms isolation, and act as an interface between field logic signals, eliminating ground loop problems  and isolating the host computer from potentially damaging voltage spikes.

The ICP DAS PEX-P64 board also include an onboard Card ID switch that enables the board to be easily recognized via software if two or more cards are installed in the same computer. The PEX-P64 board is designed as an easy replacement for the ICP DAS PISO-P64U board without requiring any modification to either the software or the driver.

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.

Lead time: 5-7 working days from receipt of order.
