Connection of time relay switch-on delay (Hager EZD100)?
Hello, I'm interested in the connection to this timer relay. A1=L, A2=N, and B1 is the trigger contact, so far everything's clear. I'm interested in the contacts that then transmit the voltage to the device. I think 15 is a changeover contact, 16 a normally open contact, and 18 a normally closed contact. But where do these contacts get the voltage to switch on? From A1?
Thanks for your help!

The thing behaves like a normal light switch, only that the "automatic" is actuated instead of by hand.
In the case of a normal light switch, it is also necessary to apply current so that it can switch this current.
That's the same with the relay. The circuit to be switched is connected there.
15, the contact connection is connected to 16 or to 18.
You can then feed 230V that gets the relay, 230V from elsewhere, also other phase possible or any other voltage, eg 12V from alarm systems or 24V in industrial controls, mainly only a maximum of 240V and no more than 8 amperes.
If it is a potential free contact, you can take any voltage that the contact stops according to the data sheet.
You can take them from A1.
If A 1 zb 230 V AC is applied, you can also apply 24 V DC to the potential free contact zb and switch a corresponding component with it.
