Now I'm quite confused. I've found exactly what I'm looking for, and for less than twenty dollars. I'm all set. All of a sudden, I read the application pdf for the unit. The delay on break is supposed to keep whatever powered unit (pump, motor, lamp, etc) deenergized for a set period of time following the broken circuit. This is supposed to safeguard against unwanted cycling in case power is reapplied too soon after the break.
So if you set it for 120 seconds "delay on break", mains voltage will be cut for a guaranteed 120 seconds even if power is reapplied to the relay coil. EXACTLY the opposite of what I'm trying to accomplish. I'm almost certain that some of the data sheets for these "delay on break" relays describe the delay as MAINTAINING mains power for the set period of time. Is this a matter of some nomenclature I'm not yet aware of?
Anyone know the story here? This is kind of a electrical/electronic crossover question. Perhaps I need to ask at some sort of electrical trade forum. Can anyone recommend one? This is so frustrating. The sales/tech help at Digi-key is absolutely no help whatsoever. I really can't blame them. I should be able to describe exactly what I'm looking for, but for some reason, this application just seems to confuse.
