WebMay 6, 2024 · I'm using 4n35 Optocoupler. Here's the signal flow, 230V -> Bridge rectifier + Filter -> R + R + optocoupler Input -> optocoupler output (CTR = 1) ->Arduino. Intially I thought of using 10mA as I C = I F which gives me 230V/10m=23kohm (12k + 12k standard) But this gives me an I 2 loss of 1.2 + 1.2 Watts. In case I use 1mA as I C = I F, I need a ...

Simply, the transistors in the optocouplers are NPN, so should be used for "low side switching". That is what the first circuit is doing. The second circuit is doing "high side switching" and should be done with PNP optocouplers.

Since the opto output transistor can handle the short circuit current of C1, you can eliminate R2 and D1. R1 x C1 is the R-C time constant, 4.7 ms for the values shown. This is a bit short for a bouncy switch. You want the time constant to be longer than the longest bounce pulse width. ray-ban sunglasses rb2132 new wayfarer flashWebAn optocoupler provides signal transfer between an isolated input and output using an infrared Light Emitting Diode (LED) and a silicon phototransistor (Figure1). The LED sends a beam of infrared energy to an optical receiver inside a single package with a light conducting medium between the emitter and the detector. This mechanism provides ray ban sunglasses oversizedWebDec 10, 2024 · An opto-isolator connects input and output sides with a beam of light modulated by input current. It transforms useful input signal into light, sends it across the dielectric channel, captures light on the output side and transforms it back into electric signal.
