ICP DAS PISO-P64U-24V - Universal PCI, 64 isolated digital input
by ICP DAS

The PISO-P64U-24V universal PCI card supports 3.3 V/5 V PCI bus. These cards provide 64 optically isolated digital input (DI) channels that use either an internal or external power supply that can be selected via a jumper. The internal power is provided by an onboard isolated DC/DC converter that provides 3000 VDC isolation and is used for connecting dry-contact input devices. These DI channels are arranged into four isolated banks when using four isolated external power supplies. DI channels 0 ~ 15 are allocated to bank A, DI channels 16 ~ 31 are allocated to bank B, DI channels 32 ~ 47 are allocated to bank C, and DI channels 48 ~ 63 are allocated to bank D. The onboard photo couplers provide 3750 Vrms isolation, and act as an interface to field logic signals, eliminate ground-loop problems, and isolate the host computer from damaging voltages. These cards contains has a single DB-37 connector and a single 40-pin male header, each of which contains 32 input channels. PISO-P64U-24V also adds 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 PIO-P64U cards in one computer.
