Optocoupler Arduino 24V at Claire Fahey blog

Optocoupler Arduino 24V. I need to switch up to 16 24v relays. A basic optocoupler uses a led. I have the system currently working using a tlp521 oprocoupler and bc337 npn. Mct2e is 6 pin optocoupler but here we are using only 4 pins as shown in the figure. The circuit of arduino and optocoupler interfacing is shown in figure 2. It is built around arduino nano, mct2e optocoupler, mosfet, resistor, and other few components. I am again assuming 1.4 v for the optocoupler and 2.1v for the green led and guessed 20ma for those optoelectronics. So moving to a teensy lc instead of the arduino mega, an esp8266 wifi module instead of the ethernet shield, and hoping to use. Pc817 optocoupler pinout, working and example with arduino. Pc817 is an optoisolator consists of an infrared diode and phototransistor. As such i would like to electrically isolate the arduino and the 24v circuit using an optocoupler to switch the 24v on and off with a 5v digital signal from the arduino. In electric circuits, we use mostly filters.
