Working Principle

The EL1017-G optoisolator integrates an infrared LED and a photovoltaic output transistor. When voltage is applied to the LED, it emits an infrared light which is absorbed by the photopransistor. This voltage causes the phototransistor to turn on, which in turn controls the output voltage. Depending on the voltage applied, the circuit can be modified to provide either a high logic level or a low logic level at the output. Furthermore, the EL1017-G can also be used in combination with logic circuits to detect short circuit and overvoltage conditions.

Conclusion

The EL1017-G Optoisolator is a powerful, versatile device that can be used in a variety of electronic applications. By utilizing the combination of an infrared LED and a photovoltaic output transistor, the EL1017-G provides high input-to-output isolation, high common mode rejection, low power consumption, and a wide operating temperature range. This makes it an ideal component for industrial, automotive, and domestic electronics.
