Introduction
The PEX-P8R8i board utilizes the PCI Express bus and is designed as an easy replacement for the PISO-P16R16U board without requiring any modification to either the software or the driver.
The PEX-P8R8i board provides 8 photocoupler Digital Input channels with 3750 Vrms isolation protection, and allows the input signals to be completely floated to prevent ground loops. The boards are also equipped with 8 Relay Output channels that can be used for controlling the ON/OFF state of external devices, for driving external relays or small power switches, or for activating alarms, etc.
