Detailed Description
The 12V Power Relay is commonly used in electronics, automation, and control systems to safely switch appliances, motors, lighting, and other electrical loads. By using a low-voltage control signal from a microcontroller or control circuit, the relay allows you to control higher voltage AC or DC devices without direct electrical connection.
This relay operates using a 12V DC coil, which when energized, activates an internal electromagnetic switch that changes the state of the contacts (NO/NC). This provides safe isolation between the control side and the load side, helping to protect sensitive electronics.
It is widely used in home automation systems, industrial control panels, robotics, and smart IoT applications. The relay can be driven using a transistor or relay driver module when interfacing with microcontrollers.
