I would like to replace the relay which triggers a water pump, with a relay which times out after, say, 10 minutes. And if it times out, it stays locked out until reset.
Needs to be 230v AC on both sides of the relay.
If it doesn't time out, the next time it's triggered it should come on normally.
I've spoken to everyone from RS to Farnell, and they have everything but that device. Making me wonder if I was using the wrong terminology.
I've got about 10cm by 12cm space to replace the standard relay currently inside the box (an ancient RS 348-403).
(I noticed that the question warns me that "The question you're asking appears subjective and is likely to be closed". It either exists as a thing, in which case it has a particular name it's known by (eg: "no-retriggering timeout relay"), or it doesn't. I'm asking a question in the vein of "what's the name of the device which reduces voltage". Note that the question is clearly "what is the name of", rather than "what do you call" - the latter would indeed be subjective!)
