A dual optocoupler is used in a configuration which has the same current throughout as the LEDs. Assuming similar optocoupler features the output voltage must be equal to the noninverting input voltage. Since the op amp is within a closed loop the output voltage becomes equal to the input voltage. RC and C perform as a compensation network to prevent oscillations.
