The CompactPCI card cPCIDIO offers 32 optically isolated digital I/O, optimised for 24V. Each digital I/O can be used as digital input or output and interrupt source as needed. The board also features a Timer an and a Watchdog for the outputs.

The main applications areas are automation technology, process technology, measurement technology, control technology and in construction of test control units.


  • 32 digital I/O, optically / galvanically isolated from the computer and optimised for 24V (binary)
  • Each IO freely usable as an input or output and interrupt source
  • Galvanic isolation voltage min. 1500Vrms


  • Max. 1A output current per output
  • Direct connection of resistive, capacitive or inductive loads
  • Permanently short-circuit proof with automatic restart attempts and overvoltage protection
  • Short-circuit recognition for diagnostic purposes
  • Programmable, computer-independent Watchdog for the outputs


  • Switching threshold optimised for 24VDC
  • Input current at 24VDC approx. 3 mA each input
  • Each input can trigger interrupts, with programmable edge
