2 Channel 5V Relay Module

Overview

Take control of high-power devices with the 2 Channel 5V Relay Module from MOKWN. This compact yet powerful relay board lets you switch two independent AC or DC loads (up to 10A each) using the low-voltage signals from your favorite microcontroller. Whether you're automating your home, building an IoT project, or prototyping an industrial controller, this module provides a safe and reliable interface between your logic-level electronics and high-voltage appliances.

Key Features

• Dual Relay Control: Two independent channels to manage separate devices.
• High Switching Capacity: Each relay handles up to 10A at 250VAC or 10A at 30VDC.
• Low-Voltage Trigger: Easily controlled with 5V logic from Arduino, ESP32, ESP8266, Raspberry Pi, and more.
• LED Indicators: Visual status for each relay and power input.
• Screw Terminals: Secure and convenient wiring for both control and load connections.
• Optocoupler Isolation (on most versions): Provides electrical isolation between the microcontroller and the relay, protecting your board from voltage spikes.
• Standard Interface: Includes VCC, GND, and two signal pins (IN1, IN2) for straightforward integration.

Technical Specifications

• Control Signal Voltage: 5V DC
• Relay Rating: 10A @ 250VAC / 10A @ 30VDC

Applications & Use Cases

• Home Automation: Control lights, fans, and appliances with smart switches.
• IoT Projects: Integrate with ESP32/ESP8266 to build Wi-Fi-controlled relays.
• Robotics: Actuate motors, solenoids, or other high-power actuators.
• Industrial Control: Prototype PLC-like controls for machinery and equipment.
• Educational Projects: Teach relay principles and microcontroller interfacing.
• Smart Switching: Automate power to devices based on sensor inputs.

What's Included

• 1x 2 Channel 5V Relay Module
• (Screw terminals pre-soldered on the module)

Compatibility

Compatible with any microcontroller or development board that provides a 5V logic level and sufficient current (typically >20mA per channel). This includes Arduino (Uno, Mega, Nano), ESP32, ESP8266, Raspberry Pi (with level shifter if using 3.3V logic), STM32, PIC, AVR, and many others.

MOKWN Recommendation

This 2 Channel 5V Relay Module is a must-have for any maker or engineer working on automation projects. Its dual-channel design, robust switching capability, and easy interface make it a versatile addition to your electronics kit. For beginners, we recommend pairing it with an Arduino starter kit. For advanced users, consider using it with an ESP32 for IoT applications. Always ensure your load current does not exceed the relay's rating and use appropriate safety precautions when working with mains voltage.
