Hello, thanks for taking time and possibly helping me understand some of the components in this circuit. I am looking at adapting this circuit for 24V (which really means close to 30V). [APS.jpg] IC1 is a PIC817 and according to the datasheet ( PC817 Datasheet ) it can handle up to 80V (VCEO= max 8…

Need help understanding components

1N1524 = 12V 1W zener diode. so yeah, a typo (missing '1')
