Relays

Relays Description:

A relay is an electrical control device designed to respond to a specific amount of input. It maintains this input long enough to effect a predetermined change in an electrical output circuit. When the input level decreases to a certain threshold and stays there sufficiently, the relay reverts to its original state. As an electronic control element, relays are integral for extending control ranges, enabling automatic remote control, and facilitating detection.

Quarktwin focuses on several key testing parameters to ensure the reliable operation of relays: actuation value, contact resistance, mechanical lifespan, contact voltage, electrical lifetime, and overload capacity. Relays are categorized based on their operating principles, including electromagnetic, induction, electric, and electronic relays.

Serving as an automatic switch with an isolation feature, relays are extensively used in various fields like remote control, telemetry, communication, automatic control systems, mechatronics, and power electronics. Quarktwin offers a diverse range of relay products, including power relays, solid-state relays, time-delay relays, automotive relays, and safety relays.
