Relay Module

A relay module is a device that allows an electrical circuit to be controlled by a switch. It consists of a coil of wire that, when energized, creates a magnetic field that activates a switch. The switch can then be used to control an electrical circuit.

Relay modules are commonly used in electronics projects to switch electronic devices on and off. They are especially useful for controlling devices that are powered by high-voltage AC circuits, as they provide a safe way to control these devices using lower-voltage DC circuits.

There are many different types of relay modules available, each with its own unique features and applications. When choosing a relay module for your project, it is important to select one that is compatible with the power requirements of your device and that has the correct number of channels for the number of devices you wish to control. If you’re looking for a reliable and affordable relay module manufacturer, Shenle is a great option. Contact us today for factory pricing.

Relay Module Function

A relay module is an electronic component that allows you to control a high power circuit using a low power signal. When the control circuit sends a signal to the relay module, the relay closes its contacts, allowing current to flow through the high-power circuit. This can be used in various applications such as controlling lights, motors and other electrical equipment.

Relay modules can also provide isolation between control circuits and high power circuits. This is because the contacts of the relay are electrically isolated from the coil, which means that the control circuit is protected from any voltage or current spikes that may occur in high power circuits.

Relay Module Uses

Relay modules are versatile components. They provide a reliable and efficient method of controlling high-power loads using low-power signals.

Here are some common uses for relay modules:

Home Automation

Relay modules can be used in home automation systems to control lights, fans, and other appliances. For example, a relay module can be used to turn lights on/off when motion is detected or at predetermined times.

Industrial Automation

Relay modules are widely used in industrial automation systems to control large machines or equipment. They can be used to control motors, pumps, valves and other equipment.

Automotive Applications

Relay modules are used in the automotive industry to control various systems including lights, fans, and motors. For example, they can be used to turn on/off headlights, windshield wipers and other systems.


Relay modules are commonly used in robotics to control motors and other devices. They can be used to control the movement of robotic arms, the opening and closing of grippers, and other functions.

Security Systems

Relay modules can be used in security systems to control access to doors, gates, and other entry points. They can be used to trigger alarms, turn lights on/off, and activate other safety features.

HVAC Systems

Relay modules are used in heating, ventilation, and air conditioning (HVAC) systems to control fans, pumps, and other equipment. For example, they can be used to turn on/off a blower motor in a furnace.
