A high-quality, imported 5V relay
module designed to control high-voltage electrical devices with a low-power 5V
control signal. it enables safe switching of AC or DC devices from
microcontrollers and other low-power systems.
Description:
A 5V Single-Channel Relay
Module is an electromagnetic switch used to control high-power
electrical devices using low-voltage signals from microcontrollers
like Arduino, PIC, Raspberry Pi, and ESP32. It allows a 5V DC signal to
switch AC (up to 250V) or DC (up to 30V) loads. The module includes
an optocoupler for isolation, a flyback diode to protect against
voltage spikes, and indicator LEDs for status display.
Specifications:
Operating Voltage: 5V DC
Relay Type: SPDT (Single Pole Double Throw)
Load Capacity:
AC: 250V @ 10A
DC: 30V @ 10A
Trigger Voltage: Low-Level Trigger (0V
activates the relay)
Optocoupler Isolation: Yes (for better
protection and stability)
Indicator LEDs: Power and relay status LEDs
Control Signal Voltage: 3.3V - 5V
(compatible with microcontrollers)
Module Dimensions: Approx. 50mm × 26mm ×
18mm
Applications:
Home Automation: Controls lights, fans, and
appliances remotely.
Industrial Automation: Controls motors,
conveyor belts, and machinery.
IoT Projects: Enables smart home device
control via Wi-Fi/Bluetooth.
Security Systems: Activates alarms, sirens,
and door locks.
Motor and Pump Control: Turns motors and
water pumps on/off.
Remote Switching: Works with wireless
control modules (RF, GSM, IoT).
HVAC Systems: Regulates heating and cooling
units.
