The 2-Channel 5V Relay Module allows you to control two high-power devices independently using 5V TTL signals from a microcontroller such as Arduino, PIC, ARM, or MSP430. Each channel features a relay with screw terminals and an LED indicator showing the relay state.
The compact modular design makes it easy to integrate into breadboard or project enclosure setups for home automation, motor control, and other switching applications.
Key Features
- 2 Independent Channels – Control two devices separately
- 5V Relay Coils – Powered directly from 5V microcontroller supply
- TTL Compatible – 5V/12V/24V TTL-level control signals
- Status LEDs – Visual indication of each relay state
- Screw Terminals – Secure connections for high-power loads
Specifications
- Drive Current: 20mA
- Control Signal: 5V/12V/24V TTL level
- Max Switching Voltage: 250V AC / 30V DC
- Dimensions: 35 × 50 × 15mm
Ideal For
- Home automation and smart switching
- Motor and pump control
- Lighting control systems
- Arduino and microcontroller relay projects
Package Contents
- 1× 2-Channel 5V Relay Module
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
