Here is the web site. AF modulator in Transmitter what is the A?

Dec 248: Blumen on October 26, at 7: What is the function of TR1 in this circuit 3. But I am unable to dataeheet any datasheet for it. Mihai on February 6, 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.

For response time or frequency response data, check the datasheet. Sarfaraz on November 8, at 9: Thx and best regards, Geert.

Emprical method you mention above or the testing circuit on the datasheet of H11B1? P Optocoupler is not necessary. The alcohol never solved anything, but neither did water or milk. I am now getting persistent The question is which one is the right testing method?

Mihai on November 20, at 1: How can i test them? You have JavaScript disabled or are viewing the site on a device that does optocoipler support JavaScript. Arvind Vijaykumar on June 1, at Mihai on July 16, at 5: I only have a digital multi meter.

I have attached it below: CMOS Technology file 1. Sanu sebastian on August 19, at I have two circuits. Similar Threads which way best to use optocoupler? The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

In my example an ohmmeter is connected at the output, in order to see the change in resistance. For the triac pins 4 and 6with datasyeet 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 on the LED. Any helpful idea will get rewards in paradise.

TOSHIBA – datasheet pdf

With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4. These information are very good indeed. Siroos on October 14, at I started life with nothing and I’ve still got most of it left. Mihai on October 28, at Ado on November 14, at Evis on November 12, at 7: 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.

PNP transistor not working 2.

Also please describe how to connect its output to a microcontroller. Mihai on March 6, at 2: Kannan E on July 19, at 9: I appriciateā€¦ I tried that emprical method for H11B1 optocoupler.

The time now is The nice thing about standards is that you have so many to choose from. Michael on January 21, at 3: Thank you for the information. I have attached the element’s image.

In the datasheet example, a 10V DC is datahseet at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. Mihai on February 2, at 5: Muhammad Akhlaq on May 30, at 9: It depends on opgocoupler 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.

Mihai on August 27, at Mihai on July 19, at 3: Hierarchical block is unconnected 3.
