I found the ACS108-6SA that seems to fit my needs.
1) I will control the gate with my stm32G0B1 uC.
I really don't understand why I have to connect the 24VAC Neutral to the +3.3VCC of the MCU ! It sounds like dangerous no?
i can understand that the current for the gate need to loop somewhere but why to connect the +3.3v to the neutral ?
This device seems to fit my needs and seems to have been designed for this purpose, but the schematics looks really strange at the moment to me.
2) Concerning my need to switch on / off big pump grundfos sba3-45a that is 230vac. this pump looks to have a big capacitor Should i use triac like T410 ACST1235-7GTR for example or ACST1635-8FP ?
I have also pure inductive 88W air bubble to connect on it that pollute a lot the 230vac line when switch off.
