Relays

A relay is an electrical control device that can be given a defined input quantity and held long enough to cause a predetermined step change in the controlled quantity in the electrical output circuit. When the input quantity is reduced to a certain level and held for a long enough time, it is then restored to its initial state.

General Information

Relays are automatic switching elements with isolated functions and are widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronics, and are one of the most important control elements.

Features

Relays
Reliable contacts: the contacts of the relays are mechanically constructed and therefore have good mechanical strength and stability; High load capacity: relays are capable of controlling high power loads; Stability and reliability: relays have the advantage of a long life, are not susceptible to external interference and are not easily affected by changes in supply voltage; A wide range of types: relays are available in many different types to meet the needs of different applications; Flexible and adaptable: relays are suitable for a wide range of electrical control systems and can flexibly control the switching of circuits; Safety and reliability: relays are able to isolate and protect against circuit failure due to conditions such as load faults; Easy to maintain: relays are easy to maintain and replace due to their relatively simple mechanical construction;
