Industrial relays are essential electrical components used in automation systems to control and manage power circuits. These devices operate by using an electrical signal to open or close a set of contacts, thereby enabling or disabling the flow of current in a system. Relays are particularly important in industrial environments where they help manage high-power loads, protect circuits from damage, and ensure the smooth operation of machinery and equipment. In this article, we will explore the different types of industrial relays, their applications, and the key considerations when selecting a relay for industrial use.
