Optoisolators - Logic Output, such as H11L3VM, are unique and influential electrical components used in a wide range of applications. They are designed with an incredibly high level of isolation between input and output for the protection of sensitive circuits from interference. In this article, we will explore the application field and working principle of the H11L3VM Optoisolator.

The H11L3VM contains a infrared LED and a separate photovoltaic module. The LED connected to an input signal creates light when an input current is present, and the photovoltaic module receives this light and generates an output current. This input/output current pair amounts to electrical isolation, meaning that the input current is not connected to the output current. The output current is also constant, no matter whether the input current is high, low, or changes over time. The current capacity ranges from 5mA to 40mA, and the peak voltage rating is up to 50V.

The H11L3VM Optoisolator is used in a variety of applications, such as automotive electronics, computer systems, electronic machine tools, and communication systems. In automotive electronics, the H11L3VM can be used to interface different systems with one another, protecting sensitive circuits from interference and providing isolation from high voltages. In computer systems, it helps to control logic and send out electrical signals, allowing various pieces of hardware to communicate even with different voltage levels. It can also be used in electronic machine tools, as well as for audio and control potentiometers. And in communication systems, it helps protect sensitive circuits from interference, resulting in better signals and improved transmission rates.

The working principle behind the H11L3VM Optoisolator is quite simple. When an input current is present, the LED generates light, and the photovoltaic module converts this light into an output current. This output current is then amplified by the photopolymers or an amplifier, creating a high-level output voltage.

At the same time, this output voltage is isolated from the input voltage, preventing it from being affected. Additionally, the H11L3VM features a Schmidt trigger circuit, which helps filter out low-frequency noise and provide a high accuracy output voltage. The output current is also constant, meaning that the voltage output remains constant over varying input current.

The H11L3VM Optoisolator is a valuable component for a wide range of applications, offering users an incredibly high level of isolation between input and output. Not only can it protect sensitive circuits from interference, but it can also increase the accuracy and reliability of the system by providing a constant output voltage. All of these features make the H11L3VM a powerful and useful device for multiple applications.
