A high-quality,
imported 5V relay module featuring two channels for controlling two
high-voltage devices simultaneously. Ideal for automation, home automation, and
DIY projects, it allows safe switching of AC or DC devices using a 5V control
signal from microcontrollers or other low-power systems.
Description:
A 5V 2-Channel
Relay Module is an electrically operated switch used to control
high-voltage appliances using low-power signals from microcontrollers
like Arduino, PIC, Raspberry Pi, or ESP32. It contains two relays,
allowing independent control of two different AC/DC loads. These relays
can switch high-power devices (up to 250V AC or 30V DC, 10A) using
a low-power 5V signal.
The module
features optocoupler isolation for added protection and includes
built-in flyback diodes to prevent voltage spikes when switching off
inductive loads like motors or solenoids.
