DC 5V 30A High Power 1-Channel Relay Module is a robust switching module designed for controlling high-current AC and DC loads using microcontrollers and automation systems. Equipped with a 30A high-power relay and optocoupler isolation, it provides reliable operation, electrical protection, and improved noise immunity. The module supports both high-level and low-level triggering through a configurable jumper, making it compatible with Arduino, Raspberry Pi, ESP32, STM32, and other control platforms. Featuring onboard status LEDs, screw terminals, and mounting holes, it is ideal for home automation, industrial control, motor switching, and high-power electrical applications.

وحدة ريليه عالية القدرة 5 فولت 30 أمبير بقناة واحدة هي وحدة تحكم قوية مصممة لتشغيل وفصل الأحمال الكهربائية ذات التيارات العالية باستخدام المتحكمات الدقيقة وأنظمة الأتمتة. تحتوي على ريليه بقدرة 30 أمبير مع عزل ضوئي Optocoupler لتوفير حماية أفضل وتقليل التشويش الكهربائي. تدعم التشغيل بمستوى إشارة مرتفع أو منخفض من خلال وصلة اختيار (Jumper)، مما يجعلها متوافقة مع Arduino وESP32 وRaspberry Pi وغيرها. كما تتميز بمؤشرات LED، وأطراف توصيل لولبية، وثقوب تثبيت، مما يجعلها مناسبة للأتمتة المنزلية والتحكم الصناعي والمشاريع عالية القدرة.

Relay Modules

The DC 5V 30A High Power 1-Channel Relay Module is a heavy-duty relay interface board designed to safely control high-current electrical loads from low-voltage control systems. The module incorporates a high-quality 30A relay capable of switching up to 250V AC or 30V DC, making it suitable for demanding industrial and automation applications.

An integrated optocoupler isolation circuit separates the control and relay sections, improving system stability and protecting sensitive microcontrollers from electrical interference. The module supports both high-level and low-level trigger modes, selectable through an onboard jumper.

With power and relay status LEDs, secure screw terminals, and mounting holes for installation, this relay module offers a reliable solution for switching motors, pumps, heaters, lighting systems, and other high-power devices.
