Flexible Realization of Simple Safety Requirements

with SIRIUS 3SK1 Safety Relays

Flashing lights, applause and happy prizewinners: Siemens was presented with the GIT Security Award 2014. After nomination by top-class jury, Sirius 3SK1 safety relays received the majority of the votes in the reader's survey category Safe Automation.


Overview

Are you looking for a rapid and easy way to realize safe systems? We have the solution: SIRIUS 3SK1 safety relays. The new safety relays offer outstanding simplicity, flexibility and efficiency. Their modular design ensures eased system planning, commissioning and expansion. They support the implementation of simple safety functions such as EMERGENCY-STOP and protective door monitoring up to SIL 3 and PL e - easily, without any programming knowledge and in minimum time.

The safety relays are certified in accordance with IEC 62061 and ISO 13849-1 and are internationally applicable.

To account for various requirements, the safety relay is available as Standard and Advanced basic unit range. Both device versions can both be used for stand-alone and integrated solutions.

Simplicity

The new safety relays offer convincing advantages:

  • Clearly structured product portfolio

  • Integrated functionality

  • Minimum wiring expenditures


Flexibility

You want to evaluate multiple sensors or safely disconnect multiple actuators?

Also this is supported by the new SIRIUS 3SK1 safety relays. Depending on the application, the basic unit can be flexibly expanded by input and output modules. This is owed to the safety relays' modular system design and integrated functionality. The solution is always individually matched to the application.

 

System expansion

The SIRIUS 3SK1 Safety Relays give you flexibility in configuring and commissioning, and even when expanding or adapting plants. This animation shows how easy it is to expand when the productivity of the plant is to be increased with a second conveyor belt. Simple adaptation is possible thanks to the modularity of the 3SK1 system.


Efficiency

The new SIRIUS 3SK1 safety relays can be seamlessly integrated in the automation technology concept. This ensures minimized engineering and training expenditures, which positively influences the system availability.

The safety relays' modularity ensures your flexibility.

Excellent Design

SIRIUS 3SK1 safety relays win iF product design award. An international panel of 49 judges was impressed by the design. The enclosure concept combines enhanced functionality with a slim design. It is also standard for all devices.

The enclosure concept scores with:

  • Needle-sharp laser labeling

  • removable terminals and hinged covers

The winning enclosure is also used for several systems. Not only safety relays but also motor starters are housed in the same enclosure.
