How are the opto devices failing? Input side or output side? If it is the input side the circuit driving the LED is not shown. What is it? Reverse voltage to the LED, according to the data sheet, should not exceed 5V.
How is the 12V supplied to the bottom opto's?Thanks your support. opto output side failing suddenly . (only bottom both opto output side failing)
