Hi,
i am thinking of using an electromagnetic relay but the relay should be "power relay" as attached below. The relay should be controlled by an optocoupler, ie the optocoupler should be controlled by the microcontroller and the optocoupler should release 12Vdc voltage to the relay.
ps ...
thank you for your replica, the electric boiler will be used for home heating and will be 3 phase which will have 24 kW. While the board will contain 8 relays, so through the relays the heaters will be controlled The water temperature will be max 75 ° C and the water temperature in the water...
