Connecting to irrigation valve

badgandalf

Hi all,

I want to connect a shelly one to control a 24 V irrigation valve. The shelly would get 220 V AC input and I need to get 24 V output. Is that possible? How should I do it?

Thanks a lot,

Ignacio

You need an additional transformer that supplies the 24V.

The Shelly is not a transformer. But it would be better if the Shelly is also operated with 24VDC.

Thanks. So I understand I have to supply 24 V in to get 24 V out.

The shelly 1 has a dry contact. (Potential free) What you feed into I comes out of O. L, N and SW can have a different supply, but for safety reasons the advice is to operate them with 24V. take a look at the connection diagrams, maybe it will be more understandable for you.
