NPN I/O

NPN I/O is a high speed optically isolated digital Input/Output node with NPN format. In addition to the standard E-Node 32bit processor and memory with full programmability and networking it offers the following features.

Hardware Features

  • 10 Optically isolated Digital Inputs/Outputs.
  • Fully protected.
  • NPN format (Output driven to 0V when active).
  • Nominal 24V operation.
  • Individual I/O can be used as either Inputs or Outputs

Software Features provided by Control-C

  • Digital I/O Outputs set instantly. Inputs read every 0.0005 sec.
  • Digital I/O timed output pulses
    (period = 0.0005 to 60 sec. resolution = 0.0005 sec).
  • Digital I/O input filtering (preventing false signalling).
  • Digital I/O edge triggered software interrupts on all inputs.
  • Interrupts fully software configured and controlled.
  • Software induced interrupts by pulsing outputs.
  • Edge counting facility on all inputs.

Front Panel Indicators

  • 8 Segment Display - Status, programming progress and Communications indicator.
  • Digital I/O Status - Red LED. On = when I/O is in the active state (0V).
