5V DC SONGLE Power Relay

Overview

Take command of high-power devices with the 5V DC SONGLE Power Relay – the trusted switch for makers, engineers, and automation enthusiasts in Egypt. This compact yet powerful relay lets your microcontroller (Arduino, ESP32, Raspberry Pi, etc.) safely control AC or DC loads up to 10A, making it the essential bridge between low-voltage logic and high-power circuits. Whether you're building a smart home system, an industrial controller, or a robotics project, this relay delivers reliable, repeatable switching performance.

Key Features

• High Power Switching: Capable of handling loads up to 10A at 250VAC or 28VDC, ideal for lights, motors, pumps, and appliances.
• Low Coil Power Consumption: With a coil power of just 0.36W–0.45W, it can be driven directly by most microcontroller GPIO pins (with a transistor driver if needed).
• Long Operational Life: Rated for 100,000 electrical operations and 10,000,000 mechanical operations, ensuring durability in frequent-use applications.
• Wide Operating Temperature: Functions reliably in ambient temperatures from -25°C to +70°C, suitable for demanding environments.
• High Isolation: Coil-to-contact isolation rated at 1500VAC/min for safe separation between logic and power circuits.
• Low Contact Resistance: ≤100mΩ ensures efficient current flow and minimal heat generation.
• Reliable Pick-Up & Drop-Out: Coil pick-up voltage ≤75% and drop-out voltage ≥10% of rated voltage, ensuring stable switching.

What's Included

• 1x 5V DC SONGLE Power Relay

Compatibility

• Works with Arduino, Raspberry Pi, ESP32, STM32, and any 5V logic microcontroller.
• For direct GPIO control, we recommend using a transistor driver (e.g., BC547, 2N2222) and a flyback diode (e.g., 1N4007) to protect your microcontroller. Alternatively, use a relay module with built-in driver.
• Control AC or DC loads up to 10A (ensure your load is within the relay's rated limits).

MOKWN Recommendation

For most beginners, we recommend using a relay module that includes a transistor driver, LED indicator, and flyback diode – making it plug-and-play. However, if you're integrating a relay directly into a custom PCB or prefer a compact design, this SONGLE relay is an excellent choice. To ensure long-term reliability, always add a flyback diode across the coil and a suitable driver transistor.
