Card PCI Express 8 kênh đầu vào số DI + 8 kênh đầu ra Relay ICP DAS PEX-P8R8i CR


  • Supports PCI Express x1
  • Card ID Function(SMD Switch)
  • 8 channels relay output
  • 8 channels optically isolated digital input
  • Selectable DC signal input filter
  • AC Signal input with filter
  • 3750 Vrms photo-isolation protection


The PEX-P8R8i is a PCI Express card. Each contain 8 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 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 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.
