The 4-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 four independent channels, allowing you to control four separate circuits simultaneously.

Each channel of this relay module features a Low-Level Trigger, which means it is activated when the input signal goes low (typically 0V or ground). This Low-Level Trigger configuration enhances compatibility with various control devices and microcontrollers.

Typically, each channel provides a load capacity of up to 10A at 250VAC or 30VDC, making it suitable for a wide range of applications. You can use this module to control lights, fans, motors, solenoids, and various other electrical appliances or devices.

The module includes screw terminal blocks for easy connection to external circuits, LED indicators for each channel to display the relay activation status, and may have freewheeling diodes 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.
