Safety relays
UE45-3S1

Safety stop via time delay

Your Benefits

  • Complete monitoring and evaluation of sensors
  • Time delay provides optimal protection of brake applications
  • Adjustable time delay at the front of the device (up to 30 s) makes it easy for the user to change settings
  • Fast, tool-free exchange via coded, plug-in screw-type terminals
  • Combines the advantages of classic relays and easy circuitry

Overview

Safety stop via time delay

The UE45-3S1 safety relay monitors safety switches and emergency stop pushbuttons in applications with a safety brake.

It offers 2 safety contacts, which directly switch off some of the actuators. The other actuators must be active until the machine has come to a complete stop. These actuators can be deactivated after a certain time.

This ensures the brake stops the machine, allowing access once the machine has come to a complete stop.

At a glance
  • Ideal for evaluating emergency stop pushbuttons and safety switches
  • Cross-circuit detection and sequence monitoring at the dual-channel input signal
  • 2 N/O contacts for direct integration into a machine environment
  • 1 N/O time for stop category 1 applications, time delayed up 30 s
  • Manual or automated reset
  • External device monitoring (EDM)
  • Coded version for all slots
