Safety functions such as emergency stop, safety door or light grid monitoring can be implemented easily with the PSRmultifunction device range – and all using a single device. In total there are four function versions available each with three connection methods.

Your advantages

  • Your cost advantage compared to conventional safety relays: three safety functions in a single device
  • Space savings in the control cabinet, thanks to the low housing width of just 22.5 mm
  • Easy maintenance and startup, as no software configuration is required
  • Short installation time, thanks to the push-in connection
  • Wide usage range and low storage costs, thanks to compatibility with a wide range of sensors
  • Easy installation of the motor control, thanks to compatible connections with CONTACTRON

The multifunctional safety relays in detail

PSRmultifunction overview  

Use of three different safety functions

The PSRmultifunction safety relays have three sensor circuits which can each be wired with single or dual 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.

 

Typical applications

Use in smaller machine units  

Multifunctional safety relays, suitable for small machines

The multifunctional safety relays can be optimally used for small machines with up to three safety functions. Possible fields of application include:

  • Food processing machinery
  • Packaging machines
  • Assembly and handling machinery
