Safety relays

This product family has been phased out!
Optimal monitoring of safety switches and emergency stop pushbuttons

Your Benefits

  • Complete monitoring and evaluation of sensors
  • The sequence monitoring takes over the evaluation of non-contact safety switches
  • 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


Optimal monitoring of safety switches and emergency stop pushbuttons

The UE43-2MF safety relay monitors safety switches and emergency stop pushbuttons via cross-circuit detection, sequence monitoring, and discrepancy time monitoring. The safety relay provides both a manual and an automated reset.

At a glance
  • Evaluation unit for emergency stop pushbuttons and safety switches
  • Cross-circuit detection and sequence monitoring at the dual-channel input signal
  • Discrepancy time monitoring is possible
  • 2 safety outputs, 1 application diagnostic output
  • Manual or automated reset
  • External device monitoring (EDM)
  • Coded version for all slots
