WebJan 15, 2014 · A typical optically isolated relay requires 10 to 20 times less power than an equivalent electromechanical relay. For example, a 5 mA optically isolated relay can often do the same job as an electromechanical relay that requires anywhere from 50 to 100 mA, depending on the electromagnetic force needed to close the coil. WebThe Makerfabs ESP32-S3 Parallel TFT Touch is an excellent choice for the ESP Display family. This 3.5 inch Touch is equipped with ESP32-S3, a dual-core Wi-Fi and Bluetooth 5 microcontroller SoC that operates at up to 240 MHz. It has 4MB Flash and 320KB SRAM, making it ideal for makers interested in ESP32-S3 RISC-V architecture.
WebIsolation: I do however - think it would be best to actually have the opto-isolator actually doing isolation. Maybe this could be effectively accomplished with another wall-wart power supply? Interesting that you wanted the opto-isolator to work slowly. This stackexchange thread mentions a PS2506 with a whopping 100us rise and fall time ... Webwill address output control techniques for linear and switch mode power supplies (SMPS). Specifically, it will cover control techniques using standard phototransistors and a new family of linear optocouplers.

WebThe opto-isolators datasheet tells us that the forward voltage, (V F) drop of the input light emitting diode is 1.2 volts and the maximum forward current, (I F) is 50mA. The LED needs about 10mA to shine reasonably brightly up to its maximum value of 50mA. However the digital output port of the micro-controller can only supply a maximum of 30mA.
