Optoisolators can be used to safely and effectively transfer a signal from one circuit to another without any direct electrical connection between them. The EL817(S1)(D)(TU)-VG optoisolator is a photovoltaic output device that can provide an isolated transfer of an analog or digital signal. This type of optoisolator has an LED light source and a photovoltaic sensor that are used to transfer the signal from the input circuit to the output circuit. As long as a voltage greater than the minimum required to drive the LED is applied to the input, the photovoltaic sensor produces an isolated output voltage proportional to the input.

Application Field

The EL817(S1)(D)(TU)-VG optoisolator is ideal for scenarios where high-voltage isolation is required. It can be used to transfer signals between low-voltage control circuits and higher-voltage power circuits. It is also very useful in applications where high noise immunity is needed, as the photovoltaic output is not affected by electrical noise or radiation, allowing for reliable and precise signalling. It has a wide variety of applications including medical and industrial instrumentation, office automation, automotive systems, lighting control, and power supply circuits.

Working Principle

The EL817(S1)(D)(TU)-VG optoisolator consists of an LED light source and a photovoltaic sensor. When a voltage greater than the minimum required to drive the LED is applied to the input, the LED produces light which is received by the photovoltaic sensor. The sensor then produces an isolated output voltage that is proportional to the input voltage. The output can be used to control a relay, switch, or other type of circuit.

This optoisolator also has an extremely wide input voltage range, from 2.7V to 40V. It also has a wide current range, from 2 mA to 60 mA. This makes it suitable for a wide variety of applications, from low voltage logic circuits to higher voltage power networks.

The output of the EL817(S1)(D)(TU)-VG optoisolator is immuned to electrical noise and magnetic interference, which makes it very useful in areas where noise immunity is required. This optoisolator also provides an isolation voltage of 2,500Vrms, ensuring a safe transfer of signals between circuits operating at different voltages.

Conclusion

The EL817(S1)(D)(TU)-VG optoisolator is a great choice for applications that require high-voltage isolation and noise immunity. It has a wide input and output voltage range, wide input current range, and a high isolation voltage. This makes it suitable for a wide variety of applications, including medical and industrial instrumentation, office automation, automotive systems, lighting control, and power supply circuits.
