Safety relays

This product family has been phased out!
Time-delayed contact expansion for all safety relays

Your Benefits

  • Offers all needed contact paths in a compact form
  • Time delay for optimal protection of brake applications
  • Fast diagnostics via status information reduces downtime
  • Fast, tool-free exchange via coded, plug-in screw-type terminals
  • Combines the advantages of classic relays and easy circuitry


Time-delayed contact expansion for all safety relays

The UE11-4DX safety relay expands evaluation units from the safety relays product family group. It has four safety outputs and two application diagnostic outputs and can switch an array of actuators. All safety outputs have a predefined time delay.

At a glance
  • Contact expansions enable four additional safety outputs for evaluation units in the safety relay product family group
  • 4 safety outputs, 2 application diagnostic outputs
  • Predefined time delays
  • Feedback signal for external device monitoring (EDM)
  • Coded type for all plug-in positions
