Opto isolated switch
WebThe LT3748 is a switching regulator controller specifically designed to simplify the design of isolated power supplies using a flyback topology. No third winding or opto-isolator is required as the LT3748 senses the isolated output voltage directly from the primary-side flyback waveform. WebThis allows us to design solutions that provide an intuitive interface between your technology and your users. Advanced components include optical encoders, rotary …

WebYou may just be able to connect it (resistor plus LED) to the switch and control board ground. Or add a resistor to the third pin of the switch and put the opto-isolator between third pin and another. Which will short out the LED in the opto-isolator when the pump isn't running and the switch is in the other position. AutoModerator • 16 hr. ago. WebThe optocoupler's isolation gives you the advantage that you can place its output transistor anywhere you like, independent of the microcontroller's supply voltage. Driving the opto-coupler means driving its LED. If the microcontroller can't drive it directly you'll need a small transistor for that.
WebMay 18, 2014 · It would have optocouplers to isolate the limit switches. I'm thinking of using HCPL2631 logic level isolator . I chose the HCPL2631 because it's used by a RepRap Opto-Isolator board . This design seemed like a good starting point for me. I have a few questions: http://www.doc-diy.net/electronics/powerswitch/
