  • Usage up to category 3 according to EN ISO 13849-1
  • LED status indicators
  • Control using safety relays
  • 3 redundant time-delayed safety contacts
  • Fixed time delay of 0.5 s
  • 1 auxiliary contact
  • Earth fault/ground fault monitoring can be selected
Relay outputsThe outputs are electrically decoupled and of redundant design. ConnectionBy using suitable wiring the following function can be selected:
  • Earth fault/ground fault monitoring to detect short circuits between the connection cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.
