So when this circuit is powered the led will receive the voltage and light up. It is packaged in a 4pin dip available in wide lead spacing option and smt gullwing lead form option. Note that the timing delay response through the optocoupler in the pc817a model may not represent an accurate picture of the real delays to be expected in a physical circuit implementation. Input output isolation voltage rms is 5 0kv.
