WebMay 7, 2024 · What does the opto buy you? You’re already got a relay that provides isolation. A resistive divider may be a cleaner solution. All things considered, without a schematic, all you’re getting are guesses as to the appropriateness of an optocoupler. WebMay 16, 2016 · The optocoupler will pull the output to ground. You'll want to be careful in general how much current you expect the opto to sink/source, zero-level will start creeping up quickly. Hence the tradeoff with speed, stronger the pull-up and faster it'll go up but then your zero level can easily creep too high. May 16, 2016 at 14:30 Add a comment 0 premier tv north huntingdon

WebFig. 5.0.1 Transistor Optocouplers& Opto Sensors. Optocouplers or opto isolators consisting of a combination of an infrared LED (also IRED or ILED) and an infra red sensitive device … WebYour biggest potential problem is that the opto-coupler acts like a constant current source. As you turn it on it will always be current limited by the gate capacitance charging. In addition the Opto has to provide current through the 10k resistor, which to hold your device on (VGS > 2.5 V @10 A) requires 0.25 mA.
