Optoisolators are electronic components that integrate a light source with an electric isolation circuit in order to transfer signals between two circuits without allowing them to interfere with each other. In recent years, optoisolators have experienced a tremendous growth in their application field, and one of the most popular is the ACFL-6212U-560E. This article will discuss the application field and working principle of the ACFL-6212U-560E.

Application Field of the ACFL-6212U-560E

The ACFL-6212U-560E is typically used in logic output optoisolators applications. It has a built-in logic-level converter and can be used to optically isolate logic signals from microprocessors, FPGAs, or other digital systems. It is capable of transferring data signals up to 20 Mbps over a distance of up to 1000 feet. The ACFL-6212U-560E also has a high common-mode transient immunity of 1500V/us and is able to withstand transient voltage peaks up to 15V with a single pulse. This makes it suitable for applications that require a high level of noise immunity, such as industrial Ethernet, automotive, medical, and industrial control systems.

Working Principle of the ACFL-6212U-560E

The basic working principle of an optoisolator is to transfer the signal from one side to another with the help of a light source and a receiver. The ACFL-6212U-560E follows this principle to isolate the logic output from its input. It has an integrated transistor output which is connected to the receiver diode. When the logic input is high, the diode is turned on, which allows the light to pass through the diode. This light is then detected by the light source, which triggers the integrated transistor output. This is how the signal is transferred to the output side without allowing the two circuits to interfere with each other.

The ACFL-6212U-560E is also equipped with short-circuit and over-current protections. It provides a maximum output current of 150 mA with an operating voltage of 65 - 260V. The maximum power rating is 25W and the minimum switching frequency is 200 kHz.

In conclusion, the ACFL-6212U-560E is an optoisolator designed for logic output applications. It features a built-in logic level converter, high common-mode transient immunity, and short-circuit and over-current protections. Its features make it suitable for a wide range of applications that require noise immunity and high speed data transmission.
