Features:

  • 48 or 24 parallel lines of 82C55 digital I/O with tristate buffers prevent unintended control of external equipment
  • Compatible with Opto-22 and other industry standard I/O racks
  • High sink/source current 64mA/32mA
  • I/O pulled up to 5V for contact monitoring
  • IRQ on input change of state (COS) eliminates the need for constant polling
