Adjustable Time Relay
Traditional Cyclic Interrupter - 50/50 times, i.e. the same amount of relay work and the same amount of break
If we set e.g. 60 sec then the relay works for 60 seconds and there is a break for 60 seconds
There is a similar extended circuit breaker in another auction, but with 2 adjustable times - work and break
Relay contacts 10A NO NC (make/break)
The generator and the heart of the system is CD4541
potentiometer and DIP -y for adjusting the work and break times
The times are in 4 sub-ranges
generally from 0.5 to 3500 sec for the relay's work and break
Principle of operation of the system
After switching on the 12V power supply, the system starts cyclical operation on off....
