Industrial relays play a vital role in modern automation and control systems. These electrical devices act as intermediaries, enabling low-power control circuits to manage high-power operations. From protecting motors to automating complex processes, relays are at the heart of many industrial operations. In this article, we will explore the functions, types, and applications of industrial relays, providing insights into their significance in the industrial world.
What is an Industrial Relay? An industrial relay is an electromechanical device that uses an electromagnet to open or close a set of contacts. It allows low voltage or current signals to control larger, more powerful circuits, making it a crucial component in industrial automation and protection systems. The relay consists of two main parts： the electromagnet (coil) and the contacts. When current passes through the coil, a magnetic field is generated, which activates the contacts to either open or close the circuit. This mechanism provides control over various electrical devices and systems.
