Dear Sirs,
I have an expensive, not very reliable timer relay that I would like to
replace with something cheaper and more reliable.
(The old one is an electro-mechanical monstrosity.)
I think it is going to be a timer off delay. When activated it runs a chain for
seven seconds, then stops. There is a latch relay which latches and holds
for a while, then it is unlatched and the timer starts, runs the chain, then
stops. My problem is a second set of contacts in the timer, which serves to
disable another part of the circuit so the chain contactor will not latch itself in
and the chain keep running.
This (I hope) is what the timing diagram look like . . .
Any hints as to what I might be able to replace it with?
Thanks, Poet.
