Optoisolators - Logic Output are devices used for transmitting signals with electrically isolated circuits, and are especially useful when transmitting digital logic signals as they provide protection from interference and enhances signal quality. One of the most common examples of this type of device is the H11L2M-V optoisolator. Its application and working principle are outlined below.

Overview of the H11L2M-V

The H11L2M-V is a …… transistor output optoisolator which combines an LED, optical coupler, and signal amplifier in one package. It has a rated input voltage of 6V, a min/max current of 16mA/30mA, a peak output voltage of 400V, and a frequency range of 50kHz to 700kHz. The package is 8 pins with a side-viewable window and it has a wide operating temperature range of -55° - 100° Centigrade.

Application Fields

The H11L2M-V is used in a variety of applications including Isolated Power Supplies, Switching Circuits, Renewable Energy Power Systems, Automotive and Industrial Applications, and other high power or temperature applications. It is often utilized for signal transmission when significant signal isolation is required. It is also often used as a buffer between a logic circuit and a power circuit, and due to its high level of insulation it can protect logic circuits from any interference. Ultimately, it is an ideal choice for any device requiring a reliable signal transmission in a powerfully insulated circuit.

Working Principle of the H11L2M-V

The H11L2M-V operates by converting electrical signals into optical signals, and then back again into electrical signals. This is done via two separate circuits, the light-emitting circuit and the light-receiving circuit. In the light-emitting circuit, electrical signals energy the LED, which emits light. This light is then received by the phototransistor in the light-receiving circuit, which is then converted back into electrical current and amplified. The amount of amplification is determined by the size of the phototransistor, and this ultimately determines how much electrical current is needed to be supplied by the light-emitting circuit.

Conclusion

The H11L2M-V optoisolator is a powerful and reliable way of transmitting signals in isolated circuits. It is heavily used in applications where power and temperature sensitivity is important, and it is often used as a buffer between logic circuits and power circuits. Its two-part circuit structure of the light-emitting and light-receiving circuits makes it very efficient at its task of converting electrical signals into optical signals and back again. Ultimately, the H11L2M-V optoisolator is an ideal device for any application requiring a powerful and reliable signal transmission between electrically isolated circuits.
