A single-channel 5 V relay module that allows a microcontroller to switch high-voltage electrical devices up to 250 VAC or 110 VDC. Controlled via a standard TTL-level digital IO pin, it works with Arduino and other popular microcontrollers.
The module uses an SRD relay with optocoupler isolation (EL817) and includes a status LED to indicate whether the relay is energised. Its compact form factor is designed for dense PCB mounting.
Key Features
- Channels – 1
- Control Signal – TTL level (digital IO)
- Max Allowable Voltage – 250 VAC / 110 VDC
- Switching Capacity – 10 A
- Max Allowable Power – From C: 800 VAC / 240 W; From A: 1200 VA / 300 W
- Status LED – Indicates relay state
- Certifications – UL, CUL, TUV recognised
Ideal For
- Switching lights, motors, solenoid valves, and other high-current devices
- Arduino and microcontroller home automation projects
- Interactive installations requiring mains-voltage control
Package Contents
- 1× Single-channel 5 V 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.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
