Relay Box

A relay box is a device that contains multiple relays, which are electrically operated switches. It is used to control and switch electrical circuits or signals. The relay box typically has a number of input terminals where electrical signals or control signals are connected, and a number of output terminals where the controlled circuits or signals are connected. The relays inside the box are activated or deactivated based on the input signals, allowing the control of various electrical devices or systems. Relay boxes are commonly used in industrial automation, electrical control panels, and automotive applications.
