I’ve got a K8055 and i’d like to connect it to a relais and an external 24 volt transformator
And my question is: on which points do i need to connect it? So which connection points do i need to use?
And do i need alternating current or decent current?

Here is the example how to connect the relay. Only DC is possible to use.
