It has been designed to allow for quick response time and off-line design, taking less power to operate.

Application Field

Due to its enhanced output drive strength and quick response time, ACPL-021L-560E optoisolator can be used in various application fields. It is ideal for architectures with heavy node traffic, like those found in data centers and large banks. It can also be used in industrial automation systems which require quick and efficient responses. It can be used to increase the reliability of systems where errors in communication can have serious consequences, or in architectures where equipment needs to be isolated from each other for security reasons.

Working principle

The working principle of ACPL-021L-560E optoisolator is based on the modulation and transfer of photons across an isolated interface. The optoisolator is composed of two separated components: an LED emitter and a transimpedance amplifier detector. When an electrical signal is applied to the LED emitter, the photons emitted are then received by the transimpedance amplifier. The transimpedance amplifier then modulates the electrical signal and sends it to the output circuit. This process helps to electrically isolate the input and output circuits, allowing the output signal to remain unaffected by the input signal, even when both signals have different voltages or frequencies.

Conclusion

In conclusion, ACPL-021L-560E optoisolator is a great device that can be used to quickly detect signals with a high degree of accuracy. It is ideal for applications requiring quick response time, heavy traffic node architectures, and increased system reliability. Thanks to its isolated transistor and LED detector channels, it is able to electrically isolate input and output signals, ensuring that the output signal remains unaffected by the input signal.
