Product list Multifunctional safety relays
Several safety functions of a switching device can be processed with the multifunctional safety relays.
With the PSRmultifunction device range, you can realize simple safety functions such as emergency stop, safety door and light grid monitoring particularly easy – with just one device. In total there are four function versions available, each with three connection methods.
Your advantages

- Space saving in the control cabinet, thanks to the compact housing
- Proven safety, thanks to force-guided relay contacts
- Short installation time, thanks to the push-in connection
- Compatible with a broad range of sensors
Multifunctional safety relay
Three safety functions in just one safety relay. Safety functions already integrated into the device reduce potential wiring errors.
- Overall width 22.5 mm
- No software configuration required
- TÜV-certified
- PLe in accordance with ISO 13849 and SILCL 3 in accordance with IEC 62061
- Screw, spring-cage, or Push-in connection
- Compatible connections with the CONTACTRON hybrid motor starter
The multifunctional safety relays save space
The PSRmultifunction safety relays have three sensor circuits which can each be connected via one or two channels:
- A higher-level sensor circuit S0
- Two local sensor circuits S1 and S2
The local sensor circuits S1 and S2 each provide a standard function such as a safety door or a light grid. When a fault occurs, both sensor circuits can be reactivated separately.
The higher-level sensor circuit S0 monitors both local sensor circuits. If it is triggered, the safety circuits protected by S1 and S2 are switched off.
