lülitusmoodulid

Lülitusmoodulid, also known as switching modules or relays, are electronic components used to control the flow of electrical current in a circuit. They act as electrically operated switches, allowing a low-power control signal to switch a high-power circuit on or off. This isolation is crucial for protecting sensitive control systems from the potentially damaging effects of high voltages or currents in the switched circuit.

The fundamental principle of operation involves an electromagnet. When a small current flows through the coil of the electromagnet, it generates a magnetic field. This magnetic field attracts a movable armature, which in turn closes or opens electrical contacts. When the control current is removed, the magnetic field collapses, and a spring mechanism returns the armature to its original position, opening or closing the contacts in the opposite way.

Lülitusmoodulid are widely used in various applications, including industrial automation, automotive systems, home appliances, and telecommunications. They are essential for tasks such as motor control, lighting systems, power switching, and signal routing. Their reliability, durability, and ability to handle diverse voltage and current levels make them a versatile and indispensable component in modern electronics. Different types of lülitusmoodulid exist, including electromechanical relays, solid-state relays (SSRs), and reed relays, each offering specific advantages for particular use cases.
