Relay Module 5V 2 Channel

2 Channel 5V Relay Module – Dual Output Switching for Arduino & IoT Automation

The 2 channel 5V relay module allows you to control two high-voltage AC or DC devices using microcontrollers like Arduino, ESP32, NodeMCU, or Raspberry Pi. With built-in opto-isolation and indicator LEDs, this module is designed for safe and reliable automation in smart homes, DIY electronics, and industrial control systems in Bangladesh.

Each relay supports up to 10A, making it suitable for switching lights, fans, pumps, motors, and more.

Key Features:

• Operating voltage: 5V DC

• Trigger voltage: 3.3V/5V compatible

• Relay output: SPDT (Normally Open & Normally Closed)

• Max switching: 250V AC / 30V DC at 10A

• Opto-isolated inputs for protection

• Onboard power and status LEDs for each relay

• Screw terminals for easy wiring

Applications:

• Dual device automation (e.g., light + fan)

• IoT home control with Blynk, MQTT, or web interfaces

• Industrial relay switching with ESP32/Arduino

• Remote power control systems in Bangladesh

The 2 channel 5V relay module is a reliable and easy-to-use solution for controlling multiple high-power devices in your automation projects.
