[Did You Know?] Classification and Functions of Relays

[Did You Know?] Classification and Functions of Relays

A relay is an automatic control device that, in response to a specific input signal, either closes or opens a low‑current control circuit, thereby enabling remote control and protection. Currently, according to reports from Yuanze Relay’s R&D department, the input quantities of its relays can include electrical parameters such as current and voltage, as well as non‑electrical quantities like temperature, time, speed, and pressure. The output, in turn, manifests as contact actuation or changes in circuit parameters.

New energy vehicles

New energy vehicles

The reason high‑voltage contactors are used is that new‑energy vehicles employ high‑voltage systems. The rationale for this is that such vehicles typically require substantial power; under high‑power conditions, a low‑voltage system would result in heavy, bulky motors and thick, difficult‑to‑route wiring. To meet these power demands while keeping the system compact, new‑energy vehicles adopt a high‑voltage, low‑current configuration, which has given rise to today’s high‑voltage architectures.

New energy vehicle charging station

New energy vehicle charging station

When designing electric vehicle charging stations, it is essential to account for the new requirements imposed on components such as contactors, connectors, and cables. In particular, contactors play a critical role in ensuring design integrity and compliance with specified performance criteria. Working in concert with other power‑handling components, contactors enable precise control of the charging process and lossless switching of diverse load conditions.

Wind power plant

Wind power plant

Wind power harnesses a natural energy source and is far superior to diesel‑powered generation. However, for emergency use, it still falls short of diesel generators. Wind power should not be relied upon as a backup power source, but it can serve as a long‑term energy solution.

Smart home appliances

A contactor is essentially a switch that can control the connection and disconnection of electrical circuits, using low-voltage signals to manage high‑voltage currents. It is commonly employed in automated control circuits, where it performs functions such as automatic regulation, safety protection, and circuit switching. Additionally, it can detect faults in the power system and open the circuit to prevent further damage.

A contactor is an electrical control device that establishes an interactive relationship between a control system (also known as the input circuit) and a controlled system (also known as the output circuit). It is commonly used in automated control circuits and essentially functions as an “automatic switch” that uses a small current to control the operation of a much larger current. As such, it serves in circuits to provide automatic regulation, safety protection, and circuit switching.
