If you look at the below diagram, the top of the curve is around the 6mA point. Thanks for the write-up, and the clear explanation of optocouplers! A typical application circuit diagram to control an ACload using a Microcontroller is shown below. Depending on your circuit you may need to add a resistor on the other side of the optocoupler as well. Isolating Circuits From Your Arduino With Optocouplers: A Optocoupler also called a photocoupler, optical isolator or opto-isolator is a small chip that transfers signals between two isolated circuits using light. This meant I could easily connect it to a breadboard. The LED is terminated over a couple of pin outs, while the three terminals of the photo-transistor is terminated over the other three assigned pin outs. If you want to know more about the internal diagram of any optocoupler ic, I recommend that you check from the Philip ECG semiconductor master replacement guide book for the correct datasheet. You need to add a suitable resistor to the input, see below. Find great deals on eBay for 4n25 and 4n

An Optocoupler can do the job. The main function of an opto-isolator is to block such high voltages and voltage transients, so that a surge in one part of the system will not disrupt or destroy the other parts.

There are many types of optocoupler and you chose one based on the requirements of your circuit. As used herein: 1. The frequency of rotation can be adjusted by the trimmer R3 and by change the capacitance of The 4N25 is an industry standard single channel Phototransistor Coupler with base connection. The question was asked by one of the interested members of this blog, Miss […] I'm using an open collector comparator LM, and I want to isolate V2 from the circuit by a 4N25 optoisolator.
The value of the CTR changes depending on the input current and the ambient temperature.
