Relays
A relay is an electrically operated switch that uses a small control current to open or close circuits, allowing low-power signals to control high-power loads safely. Relays are widely used in industrial automation, power distribution, and equipment control, providing functions such as signal amplification, circuit isolation, and automatic regulation. Common types include electromagnetic relays, solid-state relays, and time relays, available with various contact configurations, coil voltages, and mounting options. With reliable switching performance and strong insulation, relays help protect equipment and ensure stable operation of control systems.
