PCI Express Card with 32 Optically Isolated Digital I/O

The PCI Express IO card PCIeDIO is a PC add-in card capable of measuring digital inputs and controlling resistive, inductive and capacitive loads in 24V DC industrial applications.

PCI Express I/O board

The card provides 32 digital, opto-isolated I/Os operating at 24V DC. Each I/O can either be used as an input or as a high side output with read-back facility. This versatility makes for multiple configurations; whether an application demands the usage of 16 inputs and 16 outputs, or 24 inputs and 8 outputs, or 3 inputs and 29 outputs, or most extreme, just 32 inputs or 32 outputs, the PCIeDIO fits. Furthermore, as up to 8 cards can be used simultaneously in one PC system, 256 digital I/Os can be operated quasi-parallel.

The PCIeDIO card uses latest FPGA technology not only to implement the PCI Express Bridge, but also to use embedded intelligence for providing many more convenient features like an on-board FIFO, programmable interrupts, programmable timer or watchdog without imposing any load on the PC's CPU.

A comprehensive, but easy-to-use software package for Windows 10, 8/8.1, 7, Vista and XP supports the PCIeDIO card on multiple versions and architectures of Windows.

  • 32 digital I/Os optimised for 24V DC, optically isolated from the computer
