Optoisolators - Logic Output

ACPL-K71T-56OE is a type of optoisolator designed for combining logic output.Optoisolators provide electrical isolation in electronic circuits and systems across two different circuits in order to isolate logic outputs from each other.Unlike other coupling approaches that require direct physical connection of the two circuits, an optoisolator provides an efficient, yet secure way to provide meaningful communication and transfer of data across two different circuits without having them connected physically.

Working Principle

The principle of the ACPL-K71T-560E optoisolator is based upon light transmission across two different paths. It features a separate LED and a phototransistor that are mounted on different sides of a package housing. The LED part of the optoisolator generates light when an external electric current is supplied to the LED, which is then transmitted to the phototransistor. The phototransistor then converts the light to electric current and this electric current is supplied to the associated electronics.

The LED and phototransistor are mounted into a housing that separates the two components physically, thus providing electrical isolation between the two circuits. The device ensures sufficient operation of the circuit by using electrical potential difference that can be as high as 60 volts. The optoisolator is also designed to ensure efficient operation of the circuit even in the presence of stray light or surrounding ambient light.

Application Field

Optoisolators are widely used in different devices and systems that require isolation between two or more circuits. The ACPL-K71T-560E optoisolator is ideal for use in various automatic control equipment, regulators, digital electronics, communication systems and automotive electronics. It is suitable for devices and systems that often sense and control logic signals.

The ACPL-K71T-560E optoisolator is ideal for connecting a wide range of input and output signals from sensing and control applications, such as signals from sensors, switches, actuators, and transistors. Optoisolators can also function as switches to switch on/off solenoids. Other applications for optoisolators include power supplies, digital memory systems, analog signal isolators, level detectors, temperature sensors, and display devices.

Additionally, the ACPL-K71T-560E optoisolator is designed for use in signal and power isolation between different circuits. With this type of optoisolator, the circuit’s logic output is isolated from short circuit, electromagnetic interface (EMI) and electrical interference, thus, enhancing the signal integrity and response time.
