The PEX-730A card is the new generation product that ICP DAS provides to meet RoHS compliance requirement. The PEX-730A card is designed as easy replacement for the PISO-730A. Users can replace the PISO-730A by the PEX-730A directly without software/driver modification.
The PISO-730A/730A-5V supports 5 V PCI bus, while the PEX-730A supports PCI Express bus. These cards provide 32 isolated digital I/O channels (16 x DI and 16 x DO) and 32 TTL-level digital 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, these DIO channels allow the input signals to be completely floated so as to prevent ground loops and isolate the host computer from damaging voltages. Each digital output offers a PNP transistor and integral suppression diode for the inductive load. The open collector outputs (DO 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 card 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.
These cards support various OS versions, such as Linux, DOS and 32/64-bit Windows 10/8/7/2008/2003/XP. DLL and Active X control together with various language sample programs 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 quickly and easily develop their own applications.
