Relays are essential components in modern electrical systems, widely used for their ability to control high-power circuits with low-power signals. A relay allows a user to switch electrical devices on and off using an electromagnet that controls a set of contacts. This simple yet powerful mechanism has applications in everything from automotive systems to industrial control and automation. However, to ensure the optimal performance and longevity of relays, it is important to understand their applications, wiring, and safety considerations. In this article, we’ll explore key Relay application notes that provide valuable insights into proper relay selection, usage, and troubleshooting.
