Isolated 8 Digital Input and 8 Relay Output Board. Includes CA-4002 D-Sub connector. PISO-P8SSR8AC cards provide 8 optically isolated DI channels and 8 solid-state relay output channels. The DI channels provide 3750 Vrms isolation protection, allowing the input signals to be completely floated so as to prevent ground loops, and isolate the host computer from damaging voltages.
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. Solid-state relays (SSR) control power circuits using a semiconductor device instead of moving parts to perform switching. The advantages of SSR include long-term reliability, no contact bounce, no sparking, silent operation, decreased electrical noise when switching, and faster switching than electromechanical relays.
The PISO-P8SSR8AC can be used in varous 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 cards can be installed in a 5 V PCI slot and support true "Plug & Play", with a single DB-37 connector provided for easy wiring.
The PISO-P8SSR8AC supports various OS version, such as Linux, DOS, Windows 98/NT/2000 and 32/64-bit Windows 7/Vista/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.
