Relay Board / Module

A relay board/module is an electronic device that allows electrical signals to be switched on and off by an external control signal. It typically consists of several relay switches mounted on a circuit board, along with the necessary control circuitry.

Each relay switch on a relay board/module can be thought of as an electronically controlled switch. When a control signal is applied to the board, the control circuitry activates the appropriate relay switch, allowing electrical current to flow through the switched contacts. This can be used to turn devices on and off, switch between different electrical circuits, or perform other tasks.

Relay boards/modules come in a variety of shapes and sizes, and can be used in a wide range of applications. They are often used in automation and control systems, such as in industrial control systems, home automation systems, and automotive systems. They are also commonly used in electronics projects and prototyping, where they can be used to switch between different electrical components or circuits.

Relay boards/modules are available with a range of different specifications, including the number of relays, the type of control signal required, and the maximum current and voltage ratings. Some relay boards/modules also feature additional features, such as protection circuitry to prevent damage to the relays or other connected devices.

Overall, relay boards/modules are versatile and reliable electronic devices that are widely used in a range of applications. They provide a convenient and flexible way to switch electrical signals on and off, and are an essential component in many electronic and automation systems
