UE48-2OS

Safety relay for all common safety applications

Your Benefits

  • One module for all common applications simplifies machine integration
  • 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

Overview

Safety relay for all common safety applications

The UE48-20S safety relay can connect all common safety solutions. In the field of emergency stop pushbuttons, mechanical and non-contact safety switches it not only controls the signals, but controls the cross circuit detection and sequence monitoring as well. The signals of the opto-electronic protective device are directly taken over and converted by the safety relay. The relay detects objects on the pressure-sensitive mat when it registers a short-circuit on the input circuit.

At a glance
  • Ideal for the evaluation of emergency stop pushbuttons, safety switches, safety light curtains, safety laser scanners, and safety pressure sensitive mats
  • Cross-circuit detection and sequence monitoring at the dual-channel input signal
  • 2 safety outputs, 1 application diagnostic output
  • Manual or automated reset
  • External device monitoring (EDM)
  • Coded version for all slots
