The PEX-P8POR8i/P16POR16i series card is the new generation product that ICP DAS provides to meet RoHS compliance requirement. The PCI-P16POR16U card is designed as a drop-in replacement for the PCI-P16POR16, while the PEX-P16POR16i card is designed as easy replacement for the PCI-P16POR16. Users can replace the PCI-P16POR16 by the PEX-P16POR16i and PCI-P16POR16U directly without software/driver modification.

The PCI-P16POR16U Universal PCI card supports both 5 V and 3.3 V while the PEX-P8POR8i/P16POR16i is a PCI Express card. These cards provide 8 or 16 optically isolated input channels and 8 or 16 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 P16POR16U series card provides 5000 Vrms and PEX-P8POR8i/P16POR16i series 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 PCI-P16POR16U and PEX-P8POR8i/P16POR16i series 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.

These cards support various OS versions, such as Linux, DOS, Windows 98/NT/2000 and 32/64-bit Windows 10/8/7/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.
