A General-purpose relay is an essential and widely used electrical device that plays a critical role in controlling circuits. By using a low-power control signal, typically involving electromagnetic forces, it allows high-power circuits to be switched on or off. These relays are designed to operate across a wide range of applications, making them versatile in various electrical systems such as automation, control panels, and safety equipment.
What is a General-purpose Relay? A General-purpose relay (GPR) is a type of electrical switch that is activated by an electromagnet. When a control current passes through the coil of the relay, it generates a magnetic field that pulls a mechanical armature, thus closing or opening the relay’s contact points. This action allows a low-power control signal to manage a high-power load, making relays a valuable tool in systems requiring isolation between control and power circuits. In simpler terms, relays act as remote control switches, enabling the activation or deactivation of larger electrical devices such as motors, lights, and industrial machinery by using a small electrical signal.
