I’ve been looking to build a timer circuit for a test device, all the circuit has to do is turn a DPST (Double pole, single throw) relay on and off every 15 minutes.
I came across the following site, which has a circuit that looks like it does what I want, what I’m not 100% cretin about is what pin to use on the Cmos 4060B:
site: 24 Hour Timer
I’ve used the email at the top of the page to contact the author, but have had no reply.
From the table for circuit {1}, setting the range connection to pin 13 looks to be what I’m looking for.
Could someone who has built similar type circuits or has used the 4060B confirm if I could get the correct 15 min on/off on that pin.
Or would I be best setting it to some other pin which has a smaller range with 15 mins being in the middle somewhere.
