The PCM-UIO96C-16 is a highly versatile PC/104 input/output module providing 96 lines of digital I/O. One important feature of this card is its ability to monitor 48 of the 96 lines for both rising and falling digital edge transitions, latch them, and then interrupt the host processor notifying that a change-of-input status has occurred. This is an efficient way of signaling the CPU of real-time events without the burden of polling the digital I/O.


  • 96 Bidirectional digital I/O lines
  • Each line is capable of:
    • Input, Output or Output with Readback
    • 12mA sink current
  • Supports 48 event sense lines
    • Generates an interrupt on signal change-of-state
    • Software selectable edge polarity for each line
    • Software-enabled interrupt for each line
    • Change-of-state latched for each line
  • Write-protection mask register for each 8-bit port
  • Compatible with industry-standard I/O racks
  • Fused +5V logic supply for I/O modules
  • 16-bit PC/104 interface
  • +5 volt only operation
