Automotive relays are a key component in many safety-critical systems used in automotive vehicles. The G8HE-1A7T-R-FR02 is a popular type of automotive relay. It is a single pole, single throw (SPST) normally open circuit type relay, commonly used in hydrogen vehicles.

The G8HE-1A7T-R-FR02 has a compact size and robust design, which make it suitable for space-constrained applications. It has a contact rating of 8A/250VAC and has a dielectric strength of 8A at 500VAC. The coil voltage range is 5-60VDC, with a coil resistance of 85-150Ω.

This automotive relay offers a number of unique features that make it a great choice for automotive applications. It has a long operating life, with a minimum of 1 million operations, and a reliable response time of less than 10ms. It also has a low power consumption of 2.0W when activated, meaning it can be used in applications where battery power is limited.

A key element of the G8HE-1A7T-R-FR02 is its built-in safety mechanisms. It has a built-in overcurrent protection, which helps protect the system from damage caused by an unexpected surge in current. It also features a thermal fuse-breaker, which will shut down the relay if it gets too hot, preventing it from causing harm to the system.

The G8HE-1A7T-R-FR02 is primarily used in engines and transmission control systems of hydrogen vehicles. In such systems, it is used to control the start and stop of the engines, as well as signal the transmission to shift gears. For example, when the driver activates the start button, the relay will enable the engine to start. As the engine is running, the transmission control system will use the relay to shift the gears, when necessary.

The working principle of the G8HE-1A7T-R-FR02 is fairly simple. When the relay receives a power signal from the fuel control system, its internal electromagnet is activated, which in turn activates the contact points to close the circuit. This enables a current to flow through the circuit and power the engine or transmission. When the fuel control system signals the relay to deactivate, the electromagnet is deactivated, so the circuit is opened and the engine or transmission is powered off.

In summary, the G8HE-1A7T-R-FR02 is a popular type of automotive relay, used primarily in engines and transmission control systems of hydrogen vehicles. Its robust design, long operating life, reliable response time, and low power consumption make it a great choice for automotive applications. Its built-in safety mechanisms ensure it will not cause damage to the system, even during an unexpected surge in current. Finally, its working principle is relatively simple, as it uses an internal electromagnet to power and deactivate the circuit.
