time relay why no output?
I bought a time relay on AliExpress. Now I'm having a problem: when the module triggers, I get no output, no matter what I try. I've already tried the other two, and the same thing happens. Then I tried a different one, and that one didn't give me any output either.
Here is the link to the product: https://de.aliexpress.com/item/1005002240092867.html?spm=a2g0o.order_list.order_list_main.82.45505c5fqbkvYE&gatewayAdapt=glo2deu

On the output page, this is nothing more than a switch. ie if you want to turn on a light, for example, then you need to have a voltage source on the output page. from there you go to COM. then proceeds from NO to the lamp and from the lamp back to the clamping source.
ATTENTION!
Even if the relay is 230 volts, please do not work with mains voltage! that can kill you life-threatening.
This also does not release a "voltage" but only a contact is switched (connection terminal NC / COM / NO)
Like a change switch.
What is a relay and How does a relay work? – YouTube
what do I have to do or buy
I don't know what you want to do
Completed my answer above.
My project is to open a turtle tank with a push rod and to close for this I already have a touch button ah bridge and the time relay. with the relay I wanted to regulate the current before.
You have to explain more.
You lack understanding Relay .
A relay is like a remote control switch which is switched via a coil.
Switching the relay after a certain timer, which makes the electronics on the circuit board.
The switches on a relay often have 3 connections, such as a conventional changeover switch (exchange contacts).
Yes, a relay is installed on your two circuit boards.
Watch the video " Switching process of a relay " here at Wikipedia, and look at the "Switch" and the 3 connections (English NC, COM, NO).
https://de.wikipedia.org/wiki/Relais
Use now 2 connectors (COM and NO) of the relay to switch another circuit (no "Touch Button" …. is also a switch/button…); Use both ports COM and NC as switches/buttons.
Good luck!
