  • Entry
  • Associated product(s)
This article contains a statement on the input extension of a fail-safe controller with 3SK1

QUESTION:
How can I multiply inputs of a fail-safe controller or read in sensors with voltages other than 24 V DC to a failsafe PLC?

 

ANSWER:

The SIRIUS 3SK1 safety relays offer such an option with their basic unit and input expansion modules. This means you can expand the number or connectable sensors for each F-input terminal of the fail-safe controller. This FAQ shows the different options for using the 3SK1 device series as input expansion modules.
