The main relay of the new Passat is located in the control cabinet or control box. A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirements. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit), and is usually used in automated control circuits. The main relay is an "automatic switch" that uses a small current to control the operation of a large current, thus playing a role in automatic adjustment, safety protection, and circuit conversion in the circuit. It is widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment, and is one of the most important control components.
