Note: Individual modules cannot be combined with the IO systems of other manufacturers.

  • Dry contact switching
  • 5 A output current per relay
  • Up to 230 V AC switching voltage per relay
  • Switching operation counter: two input words (switching operations *1,000)
  • Transient filter for protection against high-frequency relay switching (10 Hz)
  • A blue LED indicates the module's operating status
  • Green LEDs (one for each output) indicate the output status
  • Two changeover relays
