Analog countdown timer switch needed.

[outboard1196]

I'm looking for an analog timer switch that doesn't need any power to count down like This
But I need delay start , makes contact when at zero and open contacts when counting down . This is for a signal circuit so little to no current can be rated to for AC or DC . A selection of 2-6 woukd be needed (ex can be 1-6 or 2-8 hrs )

Maybe if you added more details about what you're trying to do someone here has already figured out solution.

Kitchen windup timer. You would need to open it up and connect into the "Bell" striker with a couple of wires

Its an odd task... Probably over thinking
Its for my victron SCC enable pin , I have a high absorption voltage which my inverter doesn't like so I normally just disable the charger when using the inverter to avoid any problems. And it's usually late in the day when charging is minimal so I usually leave the charger disabled till the morning and re-enable it. I'd like to set a time so it re enables after the sun is down and I don't have to remember to re-enable it.

Turn the absorption voltage down?
Alternatively, if you’re running VRM, you could use NodeRed to automate this task for you. I have mine set up to reduce maximum current as battery voltage approaches my absorption voltage to avoid spiking a cell too high.

I found this, should work
I do have a pi set up but it's probably a short term item in the system
