timer

[timegoesby]

Anyone have an idea of where I can buy a timer? Once activated, I want it to energise a relay from between 5 to 10 minutes for 10 to 20 seconds.

TIA

RS do a variety of them.

type "lighting timer" into the search box.

Chromalock make timers in Coventry. I think the number is 02476 466279

What type of voltage is operating the relay?

I bought two digital plug in the wall timers for £3.99 the pair from a local home&Bargain store near me. Aldi where also selling a similair product before xmas.

I never explained that properly. Once activated, it energises a relay every 5 to 10 minutes (selectable) for 10 to 20 seconds (selectable) and repeats the sequence every 5 to 10 minutes until de-energised.

settings I assume. It has to maintain its settings if a power outage.

They do retain their settings even unplugged, but I guess they are not the type you need as the minimium on/off period is 60 seconds

What you need is an 11 pin flip flop relay and base.Basically two timers in one,or you can use two seperate timers.As someone else says Chromalock do them so do various other manufacturers. regards,Mark.

It needs to be externally started, by an external 240v supply. When

24v it goes through its sequence. When no 240v it is totally off, with no switch of the relay contacts.

[Andy Hall]

OK. In that case, search for multifunction timer. They have those which will fit onto DIN rails (e.g. as in a consumer unit or equivalent small case, or a relay base or just standalone.

You'll also find them listed as "asymmetrical recycler"

For example, and I am sure there are others, 440-9350, would appear to do what you want.
