Opto isolated switch
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: An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators … See more The value of optically coupling a solid state light emitter to a semiconductor detector for the purpose of electrical isolation was recognized in 1963 by Akmenkalns, et al. (US patent 3,417,249). Photoresistor-based … See more An opto-isolator contains a source (emitter) of light, almost always a near infrared light-emitting diode (LED), that converts electrical input signal into light, a closed optical channel (also called dielectrical channel ), and a photosensor, which detects … See more Usually, optocouplers have a closed pair configuration.

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. WebAnalog Switches and Multiplexers mosfets.

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.
