PCM-3753I

The PCM-3753I is a 96-ch digital I/O PCI-104 module. The card emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The 96 I/O lines are divided into twelve 8-bit I/O ports: A0, B0, C0, A1, B1, C1, A2, B2, C2, A3, B3 and C3. Users can configure each port as input or output via software.

Features

  • Supports dry/wet contact
  • Keeps the last output value after system hot reset
  • Interrupt handling capacity
  • “Pattern match” and “change of state” interrupt functions
  • Output status read-back
  • Interrupt output pin for simultaneously triggering external devices
