WebThis tutorial makes use of the 4N25 optocoupler chip to allow for communication between controlling devices operating at different voltages. In my examples, I use the Raspberry Pi, which uses 3.3V DC signals, and a PLC (Programmable Logic Controller) operating at higher voltages (often 24V DC). 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 … See more Resistive opto-isolators The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s.
