Hi, I am interested in buying an ESP32 based 10io digital PLC. I would like to control LED lighting that runs on 12V AC (not DC). It is unclear to me how I can connect a 12V AC V_com to this unit. I have an external LED driver (12Vac). I want to use PWM to dim the LED.
Does this work?
LED PSU load ------- LED ------ I0.0 (is this optocoupled?)
LED PSU neutral ---------------- GNDCOM1
PLC PSU + ------------------------- Vdc
PLC PSU - ------------------------- GND
