Safety relays

Your Benefits

  • Faster response times provide short safety distances
  • Saves space in the control cabinet thanks to its compact design
  • Reduced wiring effort for fast and easy system commissioning
  • No unnecessary outputs, thereby reducing costs


The UE12-2FG safety relay is an optimal output expansion module for opto-electronic protective devices or safety controllers. By the protection of machines and plants the safety relay takes over the electrical signals and switches the connected actuators reliably.

At a glance
  • Ideal for applications with opto-electronic protective devices and safety controllers with OSSD outputs
  • Fast response time of 10 ms
  • Compact design
  • 2 contact outputs
  • Up to 20 contact outputs via cascading
  • Feedback path for external device monitoring (EDM)
  • Screw-type terminals or plug-in screw-type terminals
  • Coded plugs for all slots
