2 Ch Relay Module Board 5V Low Level - Opto-Coupler
The 2 Channel Relay Module Board 5V Low Level is a reliable interface module designed to allow low-voltage microcontrollers to safely control high-voltage and high-current electrical devices. Equipped with two independent 5V relays, optical isolation through opto-couplers, and status indicator LEDs, it provides enhanced protection and stable switching performance. Each relay can handle loads up to 10A at 250VAC or 10A at 30VDC, making it suitable for home automation, industrial control, robotics, and IoT projects. The module is compatible with popular platforms such as Arduino, ESP32, PIC, AVR, ARM, and other TTL logic systems.
تُعد لوحة الريليه ثنائية القنوات 5 فولت مع العزل الضوئي Opto-Coupler حلاً عمليًا وآمنًا للتحكم بالأجهزة الكهربائية ذات الجهد أو التيار المرتفع باستخدام المتحكمات الدقيقة منخفضة الجهد. تحتوي على ريليهين مستقلين بقدرة تحميل تصل إلى 10 أمبير عند 250 فولت AC أو 30 فولت DC، بالإضافة إلى عزل ضوئي ومؤشرات LED لعرض حالة التشغيل. تدعم التشغيل بالمستوى المنخفض (Low Level Trigger)، وتتوافق مع لوحات Arduino وESP32 وPIC وAVR وغيرها من أنظمة التحكم الإلكترونية.
The 2 Channel 5V Relay Module with Opto-Coupler Isolation is designed to provide a simple and safe method for controlling AC and DC loads from microcontroller-based systems. The module integrates two high-quality electromagnetic relays, allowing independent switching of two separate devices or circuits.
Each relay is driven through an opto-coupler isolation circuit that helps protect the control electronics from electrical noise, voltage spikes, and interference generated by switching high-power loads. This makes the module especially suitable for automation and industrial applications.
The relay inputs are configured as low-level triggers, meaning the relay activates when the input signal is pulled LOW. Indicator LEDs are provided for each channel to display relay activation status, simplifying troubleshooting and system monitoring.
With standard control interfaces and low current requirements, the module can be directly connected to Arduino, ESP32, STM32, Raspberry Pi (through suitable GPIO interfacing), PIC, AVR, ARM, MSP430, and other TTL-compatible controllers.
