1-Channel 5V Arduino Relay Module

1-Channel 5V Arduino Relay Module for Arduino PIC AVR DSP ARM. Single-channel relay, a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

The 5V relay module circuit, each one needs 15mA-20mA driver current and equipped with high current relay: DC 30V / 10A, AC 250V / 10A. This 1-channel module has a standard interface that can be compatible with a microcontroller.

This 5V Arduino relay module has on the high level and low level-trigger mode, friends who do not understand, have a look high-level trigger refers to the signal voltage between input and trigger, can be understand as a signal input with VCC cathode short-circuit triggered away.
Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understand as the signal input terminal and the GND negative electrode short circuit triggered away 1-channel relay module connection.

The 5V ONE Channel Relay Module is a reliable and efficient switching device that allows you to interface high-voltage devices (like fans, lights, and appliances) with low-voltage microcontrollers such as Arduino, ESP32, and Raspberry Pi. It operates on a 5V DC supply and uses a low-level trigger, making it compatible with most logic-level boards and sensors.

This compact module features a single electromechanical relay capable of handling 10A at 250V AC or 30V DC, making it ideal for both resistive and inductive loads. The built-in status LED provides visual feedback of relay activity, and screw terminals allow secure and quick connections.

Features of 1-Channel 5 Volts Arduino Relay Module:

• With an isolation groove in the control area and the load area.
• With power and relay action indication, bright when connect and go off when disconnects.
• When there is a signal in signal input, public side and the common side will break over.
• It can be not only used as a microcontroller development board module but also as a home appliance control.
• It can not only control the DC or AC signal but the 220V AC load.
• With a  permanent open and close vents contact.
• It is convenient to connect with blue KF301 terminal access control cable.

   ⚠️ Precautions & Usage Tips:

   • Do not exceed the rated current (10A) to prevent damage or fire risk.

   • Use a separate power source if controlling inductive loads like motors.

   • Install the module in a protective case to prevent accidental shorts.

   • Test switching circuits with multimeter before applying AC loads.

   • Double-check wiring and polarity before powering up.
