What is an Electromagnetic Relay?
An electromagnetic relay is an electrically operated switch that is used to control a circuit by an electromagnetic mechanism. It consists of a coil of wire, a movable armature, and one or more sets of contacts.
Advantages of Using Electromagnetic Relay
Reliability
Electromagnetic relays are known to be highly reliable and have a long lifespan. They can handle high current loads, high voltage, and high-frequency switching without experiencing wear and tear as fast as solid-state switches.
Durability
Electromagnetic relays are built with mechanical contacts that can withstand the stress from heavy loads. They are less likely to fail due to wear and tear compared to solid state switches.
Cost-Effective
Electromagnetic relays are generally less expensive than solid state switches and may be a more cost-effective solution for heavy load switching applications.
Handling High Inrush Current
Electromagnetic relays can handle high inrush current loads, which are commonly seen when switching inductive loads such as motors. Solid state switches may not be able to handle high inrush current loads and may get damaged if not protected properly.
