The 1-Channel Relay Module is a versatile switching module designed to control high-voltage and high-current circuits with a low-voltage microcontroller or other control devices. This module operates at 5V DC and provides a single channel, allowing you to control one circuit at a time.

This relay module features a Low-Level Trigger, which means it is activated when the input signal goes low (typically 0V or ground). It is compatible with a wide range of microcontrollers and control devices, making it suitable for various electronic projects and automation applications.

Each channel of the relay module typically provides a load capacity of up to 10A at 250VAC or 30VDC, making it suitable for controlling lights, fans, motors, solenoids, and various other electrical appliances or devices.

The module includes a screw terminal block for easy connection to external circuits, an LED indicator to display the relay's activation status, and may have a freewheeling diode to protect against back electromotive force when switching inductive loads.

This relay module is commonly used in home automation, robotics, security systems, and other applications where remote or automated control of electrical devices is required.
