4 Channels 5V Relay Module

A 4-channel relay module for controlling high-power devices from microcontrollers like Arduino, Raspberry Pi, and other development boards. Each relay has both normally open (NO) and normally closed (NC) terminals, giving you flexibility in how you wire your circuits.

Status LEDs on each channel provide visual feedback on relay state.

Key Features

• 4 Independent Channels – Control four devices separately
• NO and NC Terminals – Both connection types available per relay
• Status LEDs – Visual indication of each relay's state
• 5V Logic – Direct connection to most microcontrollers
• Mechanical Relays – Suitable for AC and DC loads

Specifications

• Channels – 4
• Operating Voltage – 5V DC
• Relay Type – Mechanical
• Outputs per Channel – NO (Normally Open), NC (Normally Closed), COM (Common)

Compatibility

• Arduino
• Raspberry Pi (with level shifting)
• AVR, PIC, ARM, MSP430 microcontrollers

Ideal For

• Home automation
• Appliance control
• Lighting systems
• Motor switching
• Industrial control projects
