selecting type of relay

Posted by Rusty on September 23, 2006, 4:51 pm

doing some shopping for time delay relays at http://macromatic.com/, well
actually
reading as they don't sell directly any TDRs

am looking for a 24 vac/vdc relay which will break a signal after a 30-40 min
interval
once energized.
I think the type is called an "Interval On" based on
http://macromatic.com/support/kb/kb.php?kba=kba116tdr

can someone confirm this, please?

Try www.grainger.com they sell a number of ice cube relays. I've used
interval time relays for that purpose. If you buy one that is double pole
double throw, it will both make and break contacts once its timed out

started search by first entering search argument "ice cube relay" without the
quotes
then searched within results (not new search) with argument "double pole"
without the
quotes
then searched within results "24" without the quotes

could not find a single 24 vac/dc with interval up to 40 min (or more)

if you have a sample product or product code, please post it

compare that to the Time Delay Relay link on

Most of the time delay relays wwg sells have 120 volt coils, but see if this
works: note, it says 300 hours, but I'm sure it's a typo.

Here is another one that may work, but I can't get a clear enough
description of its function. It says on delay/interval, if it functions as
interval, it'll work. Contact WWG technical assistance for clarification.
