I'm using the optocoupler MOC7811 for my project . But i dont know how to check it whether it's working or not ... Can anyone help me getting its circuit .... Also, please tell me thw working of this optocoupler ....
slotted couplers can be checked crude methode
apply 5 volts DC at transmitter anode pin 3 through a 220 ohm resistor.
and -ve to pin 1.
connect analog meter at reciever side keeping it to 1x ohm position and meter -ve prob at pin 2 and +ve probe at pin 4
of coupler. meter needle will move towads zero.
as you disconnect meter will show infinity.
if you want to test its speed you have to go for its funtional test.
