P49: Fast digital I/O

Expansion module
16IN+8OUT digital opto-isolated "fast" inputs and outputs
ISA bus

  • Expansion module, applicable to all pre-set boards (e.g. P48), allowing 16 inputs + 8 opto-isolated digital outputs to be added.
  • These I/Os are "fast" because they are handled directly by the host board's microprocessor.
  • The opto-isolation of the signals allows galvanic isolation from the "field", thus ensuring maximum protection against interference and accidental failure.
  • The solid-state components used for the output stages provide protection against short-circuits, over-temperatures due to excessive dissipation and reversed polarity of the external supply voltage.
