Description
5V 4 Channel Relay Module – Multi-Device Control for Arduino, ESP32 & IoT Projects
The 5V 4 channel relay module lets you control four AC or DC devices simultaneously using low-voltage microcontrollers like Arduino, NodeMCU, ESP32, or Raspberry Pi. Each relay supports up to 10A current, and the module features opto-isolation for signal protection, making it perfect for home automation, industrial control, and IoT applications in Bangladesh.
It’s ideal for projects requiring control of multiple electrical appliances such as lights, fans, pumps, or motors.
Key Features:
Operating voltage: 5V DC
Trigger voltage: 3.3V–5V logic level compatible
4 relays (SPDT) – normally open (NO) and normally closed (NC) contacts
Max switching: 250V AC / 30V DC at 10A
Opto-isolated input for safe MCU interfacing
Individual status LEDs for all 4 relays
Screw terminals for secure load connection
Applications:
Home automation (control 4 devices)
Multi-device IoT control with Blynk or MQTT
Industrial relay operations using ESP32 or Arduino
Smart farming and remote switching projects in Bangladesh
The 5V 4 channel relay module is a powerful and flexible solution for expanding automation capabilities in your embedded systems.
