Input for PWM or analog dimming signals to control brightness.

The is a Zero-Cross Phototriac Coupler (also called a Phototriac or SSR driver). It is designed to interface low-voltage control logic (e.g., microcontrollers, 5V logic) with high-voltage AC loads (e.g., motors, solenoids, heaters, lamps) by driving an external power triac or directly controlling small AC loads. sn51dp datasheet
