The PISO-725U card is the new generation product that ICP DAS provides to meet RoHS compliance requirement and is designed as completely compatible with the PISO-725. Users can replace the PISO-725 by the PISO-725U directly without software/driver modification.

The PISO-725U universal PCI card supports 3.3 V/5 V PCI bus while the PISO-725 supports 5 V PCI bus. These cards contain 8 electromechanical Relay Output channels and 8 isolated or non-isolated Digital Input channels. The DI channels can be set to either isolated or non-isolated via a hardware jumper, and each channel will generate an interrupt signal if the state is changed, which is very useful when monitoring for contact closures/openings as it is not necessary to continuously poll the inputs. The isolated DI channels use a short optical transmission path to transfer an electronic signal between elements of a circuit and keep them electrically isolated. With 3750 Vrms isolation protection, the DI channels allow the input signals to be completely floated so as to prevent ground loops and isolate the host computer from damaging voltages. The Relay Output channels 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. All relays are de-energized (switched off) during power-on, and support ON/OFF status read back. The PISO-725U/725 can be used in a variety of applications, including contact closure, external voltage sensing, load sensing and I/O control, etc.

The PISO-725U 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 supports various OS versions, such as Linux, DOS 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.
