Optoisolators consist of an input stage which consists of an LED coupled to one of a phototransistor, photodiode, or other photodetector. The light generated by the LED is isolated and cannot physically transfer the signal from input to output stages. ACPL-K73L-560E is an opto-isolator which falls into the category of opto-isolators with logic output.

Application field

The ACPL-K73L-560E opto-isolator is mainly used in industrial automation applications. It can be used for electrical isolation in relay switching, motion control, process control, power control, motor speed control, etc. Additionally, it can be used in applications that require electrical isolation such as motorized valve control, current sensing, and interface control. The ACPL-K73L-560E is also suitable for switching circuits that require a high level of galvanic isolation of low-level and high-speed digital signals, such as in security systems, or where a high level of electrical isolation is required to prevent noise interference.

Working Principle

The ACPL-K73L-560E consists of an LED which is coupled to a photodetector. The light generated by the LED is transmitted optically through an aperture in the package and will activate the photodetector, which in turn is connected to an output stage. This output stage provides a logic level signal corresponding to the input supplied to the LED side of the package. The maximum amount of voltage that can be applied to the LED side of the package is 5.5 V, and the maximum current is 20 mA. This LED will also operate in the range of 4.5 V to 5.5 V.

The logic output of the ACPL-K73L-560E is capable of providing an output voltage of 0 V to 5 V, with a maximum load of 350 mA. This output stage also includes protection circuits to protect from electrical overload, over temperature, and reverse-biased conditions. The ACPL-K73-560E can be used in a variety of applications, and is designed to provide reliable voltage switching, even at high switching speeds.
