3SK safety relays
• Key modules of a consistent and cost-effective safety chain
• Can be used for all safety applications thanks to compliance with the highest safety
requirements (PL e according to EN ISO 13849-1 or SIL 3 according to IEC 61508)
• Suitable for use all over the world through compliance with all globally established
certifications
SIRIUS 3SK1 Standard basic units
• Simple, compact devices for all important requirements for monitoring safety sensors and
actuators

Expansion units
• 3RO and 4RO output expansions for SIRIUS 3SK1 Standard basic units,
SIRIUS 3SK1 Advanced basic units and SIRIUS 3SK2 basic units
• Input expansion for SIRIUS 3SK1 Advanced basic units
• Power supply for SIRIUS 3SK1 Advanced basic units
•
Integration of 3RM1 motor starters possible and simple integration of a main circuit component
in a system configuration of the safety relays.
There is no need for complex wiring between the safety evaluation unit and the actuator.
• Expansion of the Standard device series by means of wiring
• Expansion of the SIRIUS 3SK1 and SIRIUS 3SK2 Advanced device series by means of wiring
or without wiring outlay by means of 3ZY12 device connectors
