I found one at one point, but cant find it now. And the guy who recommended it now cant recall it either.
12-24VDC. I need a device that when I apply 12 or 24v (24v preferred) it activates and passes the current through to the solenoid (external target device). Regardless of whether the power is cut, the device cuts power to the solenoid after a programmed interval has passed and waits. When power is cut from the device, it resets. Lather rinse repeat. Max power delivery is under 5 seconds. Realistically, only 1 second.
This is a mechanical doorbell solenoid that will die (melt) if power isnt removed in a reasonable amount of time. The device that activates it has demonstrated that it cant be trusted to cut power as programmed. Twice. (burning out both the device as well as the source) I figured a $20 relay is cheaper than constantly replacing $100 worth of equipment.
Or if you know of a 12/24V WIRED (traditional, old school) SOLID STATE electronic two door doorbell for $20 or less, I can go that route. Unfortunately every single solid state electronic doorbell I can find is wireless. That wont fly.
suggestions?
