Dear all,
I'm trying to design some analog circuit for water vale control, here is the simple block schematic:
So the idea is:
we have two independent sources of water and one tank and we want to fill the tank.
First we supply the water trough valve1 and measuring the water pressure in tank with the sensor and compare to a reference ( eg. if the pressure is below 1bar) then we close the valve1 and open the valve2 and give the trigger to timer delay circuit ( 12h delay) and after the delay expires the output of timer circuit closes the vlave2 and opens the valve1. This have to work in loop.
How can I design the analog timer delay circuit and the compactor, what IC should i choose for compactor and the timer delay circuit ?
This circuit can work with 5VDC or 12VDC or 24VDC.
I need to chose the latching solenoid valve and relay for the valve. Do you have any recommendation for the valve and the relay?
valve has to be 1" 4bar max pressure.
Thanks for help.
Best Regards.
