Card PCI Express 64 kênh đầu vào số (DI) cách ly quang ICP DAS PEX-P64 CR
The PEX-P64 series supports PCI Express bus. These cards provide 64 optically isolated digital input (DI) 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. These DI channels are arranged into four isolated banks when using four isolated external power supplies. DI channels 0 ~ 15 are allocated to bank A, DI channels 16 ~ 31 are allocated to bank B, DI channels 32 ~ 47 are allocated to bank C, and DI channels 48 ~ 63 are allocated to bank D. The onboard photo couplers provide 3750 Vrms isolation, and act as an interface to field logic signals, eliminate ground-loop problems, and isolate the host computer from damaging voltages. These cards contains has a single DB-37 connector and a single 40-pin male header, each of which contains 32 input channels.
The PEX-P64 series also adds a Card ID switch on-board. Users can set Card ID and then recognize the board by the ID via software when using two or more PEX-P64 series 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.
