So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level. Login nec 2561 datasheet post Please use English characters only. Ask Talk to Expert.


If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 and 4 the emitter and collectorand you should get a high resistance value both ways if the phototransistor is nec datasheet. An optocoupler or optoisolatoris a device that contains nec 2561 datasheet light-emitting diode LED nec 2561 datasheet a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.
