Optoisolators, also known as optocouplers, are a type of electronic component that provide electrical isolation between two points in a circuit. EL1013-G, a photovoltaic output optoisolator, is designed to provide general-purpose isolation for applications in mixed power domains and is well-suited for a wide range of high-linearity analog signal isolations. To better understand how the EL1013-G works, we must first take a look at its applications field and working principle.

Application Field

The EL1013-G has multiple potential applications in various industries. Communication systems in telecommunications and industrial control rely on the EL1013-G optoisolator for transforming and isolating signals. The device works to protect connected transducers and sensors from overvoltage, allowing for a high level of signal integrity and reliability. It also finds use in medical monitors, providing reliable high-speed signal and data isolation. Additionally, the EL1013-G can be found in automotive servo motors, providing accurate current measurement and control.

Working Principle

The working principle of the EL1013-G optoisolator is quite simple. It utilizes a single-channel, open-collector phototransistor output to provide low-noise, high-linearity isolation. Inside the device, a light-emitting diode (LED) is used to convert electrical signals into optical signals. These optical signals are then received by the phototransistor receptor, which converts the optical signal into an electrical signal on the opposite side of the isolation barrier. This allows high common-mode transient immunity and wide common-mode voltage range.

In addition to achieving isolation, the EL1013-G also offers built-in protection features. The output transistor of the device is protected from over-current conditions using a low-power circuit, meaning the device can work safely even in extreme working conditions. Moreover, the device limits the pulse-width to correspond with the input voltage range, meaning the device can be used efficiently even in harsh electromagnetic environments.

Conclusion

In conclusion, the EL1013-G photovoltaic output optoisolator is an excellent choice for analog signal isolation in multiple industries, thanks to its built-in protection features and high-linearity performance. The device is simple and efficient to use, and offers industrial-level signal and data isolation for various applications. This makes the EL1013-G a cornerstone of modern electronic designs.
