HCPL-540K-300 Optoisolators - Logic Output

The optoisolator HCPL-540K-300 is an isolated digital signal transmission module used in a wide variety of applications from general purpose to industrial level. Optoisolators, typically Logic Output, provide electrical isolation between two circuits while allowing digital signals to be transferred between them. This module specifically serves as an isolated high voltage digital signal transmission module.

Basic Working Principle

An optoisolator integrates an infrared LED and a photosensitive semiconductor element, such as a photodiode or a photosensitive transistor. The LED forms the input part of the circuit, while the photosensitive element is the output. When the LED is activated, it emits an invisible infrared radiation which is detected by the photosensitive element and the current is amplified, allowing it to drive the output circuit. The HCPL-540K-300 uses two internal LEDs, one of which is turned off when the input logic level is high, and the other when the input logic level is low. When either LED is illuminated, a current signal is produced which is then amplified and used to drive the output circuit.

Field of Application

The HCPL-540K-300 optoisolator has a wide range of application fields, from general purpose to industrial applications. This module is well suited for digital signal transmission in industrial systems, such as electric vehicle chargers, motor control, and elevator control. It can also be used in applications such as optical networking, robotics, microcontrollers, and process control. The HCPL-540K-300 is robust, reliable and can withstand harsh operating environments. It offers a high degree of isolation voltage and noise suppression, making it well-suited for use in devices and systems where reliable communication is required.
