I'm beginning the design of a light control system based on a microcontroller.
This is to activate the lights, what is usually used are continuous voltage relays, in ranges of 5, 12 or up to 24 VDC.
These relays are activated by the microcontroller through a transistor.
Now, we have the option of acquiring 120 Vac relays similar to RTD34615.
To activate these AC relays with the microcontroller, I plan to use a circuit similar to the following, using an opto-triac to activate the relays.
Can this electrical design have any problem or drawback?
Any comment or suggestion is welcome.
