标题: General-purpose Relay: Versatile and Essential Component in Modern Electrical Systems
A General-purpose relay is a critical electrical component used in a wide range of applications. It serves as an essential intermediary between a low-power control circuit and a high-power load, enabling the operation of electrical systems more efficiently and safely. In this article, we will explore the importance of general-purpose relays, their working principle, common types, and their vast range of applications in different industries. What is a General-purpose Relay? A general-purpose relay is an electrically operated switch that uses an electromagnet to control one or more sets of contacts. It allows a low-power signal to control higher power devices, making it a key element in various automation systems. The primary function of a general-purpose relay is to provide electrical isolation between the control circuit (usually low voltage) and the load circuit (high voltage), preventing potential damage to sensitive components.
