The 3SK121 output expansions can be used for Standard and Advanced basic units.

3SK1211 output expansion

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

3SK1213 output expansion

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

Note:

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