Thank you for the information… and i have one more p512. Geert Van Droogenbroeck on November 18, at I am now getting persistent CMOS Technology file 1.

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 optoxoupler both ways if the phototransistor is good. Distorted Sine output from Transformer 8.

I like the way you explain things. PNP transistor not working 2.

I started life with nothing and I’ve still got most of it left. I hope it helps.

How reliable is it? Looking for the pinout of P Optocoupler. If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. How to set up an optocoupler to use it in the output of flyback converter? First of all thanks for sharing such an useful information. Mihai on August 27, at P Optocoupler u can try this ring detector p52 Hi, Both methods are correct.

It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages of circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2.

In my example an ohmmeter is connected at the output, in order to see the change in resistance. You have JavaScript disabled or are viewing the site on a device that does no support JavaScript. I have connected to the Ring Red wire to the pin 1 of optocoupler tough a capacitor and a resistor in serial and have connected Tip Green wire to the pin 2 through a 1N diode. Arvind Vijaykumar on June 1, at Sanu sebastian on August 19, at P Optocoupler I seem to be unable to post a link at the moment, but google Toshiba TLP – it should get you the data sheet.

The nice thing about standards is that you have so many to choose from. Choosing IC with EN signal 2. The optocoupler is FL C F, should i just join the emittor and collector pins? How do you get an MCU design to market quickly? I guess, it should work mostly the same as a normal triac. Mihai on September 17, at Thank you for the information.

Input port and input output port declaration in top module 2. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it should be high open circuit or at least greater than 1 megohm both ways, and this resistance should go down lower than ohms when voltage is applied to the LED, and should remain low even if the voltage is no longer present dwtasheet the LED.

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.

Sunil on March 3, at 3: Digital multimeter appears to have measured voltages lower than expected. Good design is as little design as possible.
