Introduction

Relays are essential components in electrical and electronic systems, serving as switches that control the flow of electricity in various applications. From automation in industrial settings to everyday appliances, understanding how to operate and maintain these devices is crucial. This Relay Operation Guide is designed to provide insights into the principles of relay operation, installation procedures, maintenance tips, and troubleshooting techniques. Understanding Relays At its core, a relay is an electromechanical switch that uses an electromagnetic coil to open or close a set of contacts. When an electrical current passes through the coil, it generates a magnetic field that pulls a lever, moving the contacts from one position to another. This simple mechanism allows relays to control high-power devices with low-power signals.
