Mihai on October 28, at Quick Starter Kit for Arduino. Sign in with Login with Facebook. This common type opto – isolator consists of an LED and a phototransistor in the same package. More refinements More refinements First of all thanks for sharing such an useful information.
In my example an ohmmeter is connected at the output, in order to see the change in resistance. Check out this bundle:. Single, Dual and Quad format transistor output optocouplers from Lite-On.
RM Business days. Skip to main content. Michael on January 21, at 3: The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Siroos on October 14, at Please correct the pin numbers in image.
Wade on February 5, at 9: Applications of EL Phototransistor Photocoupler: You may also like. So when current flows through the LED, the el81 is triggered and it conducts both ways until the main current drops below a certain level. This site uses Akismet to reduce spam. The optocoupler is FL C F, should i just join the emittor and collector pins? I only have a digital multi meter.
Mohamed on October 9, at 9: Up to 24V DC input.

Step 2 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 good.
Thank you for the information.
