  3SK121 output expansions can be used to expand any 3SK basic device.

  3SK1211 output expansion

  A 3SK1211 output expansion is used to expand the safe circuits of a basic unit by adding another four safe circuits. These outputs have a switching capacity of AC-15 5 A at a switching voltage of 230 V. The devices can be connected to any 3SK basic unit by means of wiring. In addition, devices with a 24 V DC control supply voltage can also be connected to 3SK1 Advanced basic units and 3SK2 basic units using 3ZY12 device connectors.

  3SK1213 output expansion

  A 3SK1213 output expansion is used to expand the safe outputs of a basic unit by adding three safe outputs with high switching capacity. These outputs have a switching capacity of AC-15 10 A at a switching voltage of 230 V. The devices can be connected to any 3SK basic unit by means of wiring. As with 3SK1211, it is also possible to connect the version with a 24 V DC control supply voltage to the 3SK1 Advanced basic units and 3SK2 basic units on the 3ZY12 device connector.

  Note:

  It is only possible to expand the Standard basic units my means of wiring. Advanced basic units and 3SK2 basic units can be expanded using the 3ZY12 device connector.

  Особенности

  • Perfect adaptation of the number of inputs
  • Simple expansion of instantaneous and time-delayed safe outputs of the Advanced basic units using device connectors
  • When using the device connecter the outputs on the terminals can still be used.
  • Another two freely parameterizable shutdown functions on 3SK2 basic units when using device connectors
  • Expansion with power contacts for high AC-15/DC-13 currents in the control circuit
  • No wiring of the feedback circuit to the basic units is required when using device connectors
  • Shorter installation times
  • Less configuring and testing required
