This article discusses the application field of the HCNR201#550, as well as its working principle. Application FieldThe HCNR201#550 optoisolator is designed for use in industrial applications where electrical isolation and noise immunity are required. Its transmissive output enables it to be used in a wide range of applications, such as noise suppression in analog circuits, over-voltage protection, signal isolation, and temperature monitoring.In addition, the HCNR201#550 is suitable for a variety of industrial automation applications, including: PLCs, motor starters, and DC drives. The optoisolator is used to isolate the control logic signals from the power circuit in order to improve noise immunity and provide a higher degree of safety for data. Working PrincipleThe HCNR201#550 optoisolator is a transistor-photo-voltaic output device that uses light to provide electrical isolation between two circuits. It consists of a light source and a photo-diode. The light source is typically an LED, which emits light when an electrical current is applied. This light is received by the photo-diode, which converts the light into an electrical current. The current is then passed through a transistor, which amplifies the current and provides the output signal.The optoisolator works in two stages. In the first stage, the LED emits light when it receives an electrical current. This light is received by the photo-diode, which converts it into an electrical current. In the second stage, the amplified current is sent to the output terminal by the transistor.The HCNR201#550 optoisolator is a low power device, consuming only 5 mW of power. It is also optimized for industrial applications, providing a low transmission delay of 2 µs and a wide operating temperature range of -30℃ to +100℃. The optoisolator is also protected by a surge protector, making it suitable for use in areas with large voltage transients.ConclusionThe HCNR201#550 optoisolator is a multi-purpose device designed for industrial applications. It offers a transmissive output, enabling a wide range of applications, including communications, signal isolation, and noise suppression. Additionally, it is optimized for industrial applications, providing a low transmission delay, a wide operating temperature range, and surge protection. Together, these features make the HCNR201#550 an ideal choice for industrial applications requiring electrical isolation and noise immunity.
