Can anyone tell me in the attached circuit why use always-on optotriac to drive TRIAC?
What is the purpose of using phototriac in the circuit?
This circuit is used to control the speed of ac motor and between pin 1 and 2 of CN2 is placed the RV1 (potentiometer).
Usually use phototriac for isolation but in this circuit, we don't need isolation. There is not a DC source or microcontroller for turning on the optotriac.
