Introduction

Optoisolators are electronic components used to provide electrical isolation between two circuits. By isolating two circuits, optoisolator reduce the level of interference or noise between the two circuits, which can often be damaging. Specifically, ACPL-M484-500E optoisolator belongs to optoisolators with logic output. It has two different input/output circuitry: low-voltage input/high-voltage output, and high-voltage input/low-voltage output. The high-voltage output provides increased output strength and can drive heavier loads. In this article, the application field and working principle of ACPL-M484-500E optoisolator is discussed.

Application field

ACPL-M484-500E optoisolator is mainly used as the isolation element in AC power electronic circuits. The high-voltage output of the optoisolator allows it to drive heavier loads for improved electrical isolation. This makes ACPL-M484-500E an ideal choice for applications such as medical equipment, industrial control systems, appliances, and other AC powered devices where electrical isolation must be maintained. In addition, the optoisolator can be used in applications where a signal must be transmitted from one side of an optically isolated boundary to the other without any direct electrical connection between the sides, such as isolators for input systems.

Working principle

ACPL-M484-500E optoisolator works by using two different input/output circuitry: low-voltage input/high-voltage output and high-voltage input/low-voltage output. In the case of low-voltage input/high-voltage output, the optoisolator is composed of an LED light emitting component and a separate high-voltage output circuit. When the LED light emitting portion is energized with a low power input voltage, it produces light that is detected by the output circuit. The output circuit then pulls the high-voltage output up. In the case of high-voltage input/low-voltage output, the optoisolator is composed of an LED light emitting component and a separate low-voltage output circuit. When the LED light emitting portion is energized with a high power input voltage, it produces light that is detected by the output circuit. The output circuit then pulls the low-voltage output down.

Conclusion

ACPL-M484-500E optoisolator is an ideal choice for applications requiring electrical isolation between two circuits or signal transmission from one side of an optically isolated boundary to the other. It has two different input/output circuitry: low-voltage input/high-voltage output and high-voltage input/low-voltage output. The high-voltage output of the optoisolator allows it to drive heavier loads for improved electrical isolation. This makes ACPL-M484-500E an ideal choice for applications such as medical equipment, industrial control systems, appliances, and other AC powered devices where electrical isolation must be maintained.
