Relay Module (1-Channel)

Boost Control with Precision: 1-Channel Relay Module for Reliable Switching

Looking for a compact and powerful control solution? The 1-channel relay module is your go-to device for managing AC/DC loads with pinpoint accuracy. Designed for microcontrollers like Arduino and Raspberry Pi, this module delivers dependable switching performance with minimal complexity—ideal for home automation, industrial systems, or DIY electronics projects in Pakistan.

What Is a 1-Channel Relay Module?

A 1-channel relay module is an electronic switch that uses low-voltage signals to control high-voltage circuits. It serves as an interface between a microcontroller (like Arduino) and a power-demanding device such as lights, motors, or appliances. The single relay allows for the control of one electrical load, making it the perfect solution for simple but critical automation tasks.

Key Features of the Relay Module (1-Channel)

• Voltage Compatibility: Operates efficiently at 5V DC, making it suitable for Arduino, Raspberry Pi, and other microcontroller boards.

• Switching Capacity: Controls up to 10A at 250V AC or 10A at 30V DC, ensuring safe handling of high-power devices.

• SPDT Relay: The Single Pole Double Throw (SPDT) configuration offers both normally open (NO) and normally closed (NC) terminals for versatile applications.

• Optocoupler Isolation: Protects your control board from voltage spikes and interference through electrical isolation.

• LED Indicator: A built-in LED shows relay status, helping you easily monitor operations.

• Compact Design: Ideal for small enclosures or tight spaces without sacrificing performance.

• Screw Terminals: Makes it easy to connect wires securely—no soldering required.
