2 Channel Relay Module without light coupling 5V

The 2 Channel Relay Module is a 5 V relay board with two independent relays, letting a microcontroller switch two separate circuits. This version is without light coupling, meaning it has no optocouplers: each control input drives its relay through a transistor on the board. It is a compact, low-cost choice for controlling a pair of loads such as a lamp and a fan, or a pump and a valve, from an Arduino.

2 Channel Relay Module Specifications

• Channels: 2 independent relays
• Relay coil voltage: 5 V DC
• Isolation: no optocoupler (without light coupling)
• Control pins: VCC, GND and 2 signal inputs
• Load terminals: COM, NO (normally open) and NC (normally closed) for each channel
• Contact rating: printed on each relay body; check it before connecting a load

2 Channel Relay Module Applications

• Switching a lamp and a fan from one Arduino
• Pump and valve control for plant watering
• Reversing small DC motors with two relays
• Home automation and timer projects
• Learning how relays work in class

What's in the Box

• 1 × 2-channel 5 V relay module

Tip: Use the NC terminal for loads that should stay on until a relay is switched. Power the board from a stable 5 V supply that shares a common ground with your microcontroller, and take great care with mains voltage: disconnect power before wiring and keep the high-voltage side covered.
