Contact expansion of a fail-safe controller with 3SK1

ATTENTION: This FAQ has been updated!


How can I multiply the outputs of a fail-safe controller with minimum wiring effort and expand the switching capacity of a fail-safe controller?



The SIRIUS 3SK1 safety relays offer such an option with their basic unit and output expansion modules. This means you can increase the number of contacts as well as expand the switching capacity of the fail-safe controller up to 10 A. Another advantage is that the devices are already certified to the applicable safety standards.
This FAQ shows the different options for using the 3SK1 device series as contact expansion modules.
