Hi gerryr1gerryr1
Your Power supply confuse me,and i am no guru either….
Here are some presumptions:
1. Power Supply is 24Vac
i. In that case D3 will do half rectification for your load.
ii. No power will get to your voltage regulator as D2 block the positive half that was allowed by D3.
iii. D1 is not doing anything.
iv. I see no power getting to your OpenSprinkler
2. Power Supply is 24Vdc
i. D3 does nothing and your load has 24Vdc
ii. No power will get to your voltage regulator as D2 block the positive that was allowed by D3.
iii. D1 is not doing anything.
iv. I see no power getting to your OpenSprinkler
You need to understand that the “AC” unit can not work properly on a “DC” supply as the Triacs require AC to switch off.
If you require a “DC” to drive your load, then you need to place a AC-DC circuit on each output to drive you relays, you still have to supply the OpenSprinkler with 24Vac to make it work
