PCI-P8POR8/P16POR16 and PEX-P8POR8i/P16POR16i
The PCI-P8ROR8/P16POR16 supports 5 V PCI bus while the PEX-
P8POR8i/P16POR16i supports PCI Express bus. Each contain 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 DI channels provide 5000 Vrms 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.
The PCI-P8POR8/P16POR16 and PEX-P8POR8i/P16POR16i 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 card can be installed in PCI/PCI
Express slot and supports true "Plug & Play", with two DB-37 connectors provided
for easy wiring.
