Relejni modul 1 rele 5V opto KY-019

Zanesljivo preklapljanje za vaše projekte

The 5V single-channel relay module with optocoupler KY-019 is a popular module for controlling high-voltage devices via microcontrollers such as Arduino, ESP32, Raspberry Pi, and others. The optocoupler provides electrical isolation between the control part and the load, increasing system safety and reliability. The module allows control of AC loads (up to 250V) or DC loads (up to 30V), making it suitable for home automation, smart devices, robotic projects, and various DIY applications.

It is suitable for beginners, students, hobby projects, and professional applications where powerful consumers such as lights, motors, pumps, or household appliances need to be controlled with a microcontroller. The optocoupler enables galvanic isolation between the control circuit and the power supply, reducing the possibility of damage to the microcontroller in case of interference or overvoltage surges at the output. This is especially important when working with inductive loads such as motors or electromagnetic valves..

Ključne lastnosti

• Kompaktna in robustna izvedba

Tehnične specifikacije

Inženirski “PRO” nasvet

The module is fully compatible with Arduino IDE and most development boards (Arduino Uno, Nano, Mega, ESP8266, ESP32, Raspberry Pi). It requires a 5V logic control signal. When used with 3.3V logic (ESP32, Raspberry Pi), it is recommended to use a transistor or logic converter for reliable operation.

Primeri uporabe

• Avtomatizacija doma (luči, ventilatorji)
• RC modeli in robotika
• Industrijski krmilni sistemi
