features and benefits
The PEX-P8POR8i is a PCI Express card.
These cards provide 8 Isolated input channels and 8 PhotoMOS Relay output channels.
Both the isolated DI channels and the PhotoMOS Relay channels use a short optical transmission path to transfer an electronic signal between elements of a circuit and keep them electrically isolated.
The PEX-P8POR8i card provide 2000 VDC for DI channel isolation protection, allowing the input signals to be completely floated so as to cut down ground loops, block voltage spikes, and isolate the host computer from damaging voltages.
PhotoMOS Relays are used where it is necessary to control a circuit using a low-power signal (with complete electrical isolation between the control and controlled circuits), or where several circuits must be controlled by one signal.
These cards can be used in various applications, such as controlling the ON/OFF state of external devices, driving external relays or small power switches, activating alarms, contact closure, sensing external voltages or switches, etc. The PEX-P8POR8i card also adds a Card ID switch on-board.
Users can set Card ID and then recognizes the board by the ID via software when using two or more cards in one computer. 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.
