Hallo Syed,
15000rpm means a frequency of 900kHz! Switching speed of 4n35 is specified to be 7µsec typical, depends of course on actual design. So, I think you would need a faster opto. On the other hand, it highly depends on your code and the clock frequency of micro what maximum frequency your system can handle... Kai |
