I thought this would be SO easy to find, but no. Maybe somebody here can point me to it.
I need a cycle timer relay, adjustable for infinitely repeating on/off intervals, approximately 10 minutes on and 5 off. The timer should be powered by plugging into a standard 120v outlet, or I could hard-wire it to 120v. The relay should should switch a separate 24v DC circuit. Battery powered might be OK, but I’d much rather have the reliability of plug-it-in-and-forget-it. I want quality, not the average Lowes or Amazon junk.
Can anyone recommend a source for this? All I can find is fancy industrial equipment. Maybe I'm just calling it by the wrong name when I ask Google....

What about cycle timers?

or a Delay Relay?

I’d say that you need 2 devices.
Repeat or loop timer.
Plus a 24vdc transformer with common 120vac primary.
Does this timer run its cycle indefinitely?

Yes, I want it to run continuously, 10 minutes on, 5 off. So preferably something solid state rather than mechanical.
This looks like it would do the job, but all the YouTube videos describing it are in Indian languages like Hindi and Tamil.

After much study (learning!) I have concluded that you are exactly right.
Since a room thermostat is involved, I have ordered a 24v AC-output transformer rather than DC-output. DC would work if I set up the circuit a little differently.
Also ordered the GRT8-S1 ON/OFF Repeat Cycle Relay -- thanks, CoalisCool.... That one was a little confusing because they call it a "delay relay" as well as a "repeat cycle relay", which technically are different animals, I think.
Thanks for the help, people.

Here is a cyclic relay with two dry contacts. It is available as a panel mount or Octal base.

I looked at that and another Selec model, and found some YouTube videos explaining them in a couple of Indian languages/dialects or whatever they were. Harder to understand than the robocalls I get telling me that my internet has viruses and will be shut off if I don't pony up some cash. But surprisingly, I could pretty much comprehend how they work because there were plenty of pictures.
