WebFeb 12, 2024 · Joined Sep 17, 2013. 13,330. Feb 12, 2024. #5. The CTR for an opto with an analogue output is just the ratio of the output device current to the input diode current. For example, if the diode current is 5mA and the CTR is 120% the maximum current through the output device will be 5mA x 1.2 = 6mA. WebJun 11, 2024 · The CTR is fixed for any particular unit and can fall between the range of 50% to 300%. You have no choice or control in what you get unless you screen the …
WebJul 17, 2024 · Very simply, an optocoupler integrates an infrared LED alongside a photodetector (usually a phototransistor) and acts like an optical switch. When the LED receives an input signal, the LED turns on and supplies photons to the base of the phototransistor. This then turns on the phototransistor, allowing current to flow through a …
