Card PCI/PCI Express 32 kênh đầu vào/ra số cách ly+32 kênh đầu vào/ra số TTL (current sourcing) ICP DAS PEX-730A CR
The PEX-730A cards provide 32 isolated Digital I/O channels (16 x DI and 16 x DO) and 32 TTL-level Dgital I/O channels (16 x DI and 16 x DO). Both the isolated DI and DO channels use a short optical transmission path to transfer an electronic signal between the elements of a circuit and keep them electrically isolated. With 3750 Vrms isolation protection, the DIO channels allow the input signals to be completely floated so as to prevent ground loops and isolate the host computer from damaging voltage spikes. Each Digital Output includes a PNP transistor and integral suppression diode for the inductive load. The open-collector Digital Output channels are typically used for alarm and warning notification, signal output control, control for external circuits that require a higher voltage level, and signal transmission applications, etc.
PEX-730A cards also add 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 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.
