Introduction
The PEX-P8R8i is a PCI Express card containing 8 photo coupler digital inputs that
provide 3750 Vrms isolation protection, allowing the input signals to be completely
floated in order to prevent ground loops. Equipped with an 8 relay output channels to
enable the control of the ON/OFF state of external devices, drive external relays, small
power switches, or activate alarms. The PEX-P8R8i is fully compatible with the PISO-
P8R8, and users can easily replace the PISO-P8R8 with the PEX-P8R8i without any
need for software/driver modification when using PCI Express computers.
