Understanding the Basics of Control Relays

Over the years, we have seen a robust acceleration in the electronic field, be it automobiles, cell phones, computers, machinery, or technical equipment. However, it is important to understand that this drastic growth results from various solidly designed electrical parts that come together to pave the way for innovation and development. One such electrical part is a control relay. Now, most of us are familiar with the basic functioning of any electronic device or machinery—it uses a current/power supply to drive all the elements of its apparatus. Control relays are referred to as electromagnet devices that were developed more than a century ago. So, how do control relays function? How do they contribute to the larger electrical system? Let’s find out.

In simple terms, a control relay is an electrical switch controlled by the supply of current. The primary role of a control relay is to close or open up a switch to allow the current to flow through a conducting coil so that the coil does not come in direct contact with the switch. Now, let’s understand how do control relays operate.

Whenever current runs through a coil, it pulls in a magnetic element that effectively turns off the switch of the device. And when the flow of the current stops, the switch automatically opens. Spring is a major contributor in ensuring that the switches are working efficiently and on time. They also make sure that electronic circuits work in sync with control relays to kick off the automatic functioning of the electrical device. Dual and single switch relays are two commonly used relays in modern electric applications.

The moment current flows through a coil, it leads to the creation of two magnetic poles known as the North Pole and the South Pole. Additionally, an armature is attached to the spring inside, attracting both the poles with equal intensity. When the current running in the given coil reaches a suitable level, the pull towards the coil remains consistent. However, in a situation like this, the switch is turned on, and as the current slows down, the attraction pulls the armature back, turning the switch off. Hence, a control relay controls the electric current that powers all the electronic gadgets used in our modern society, like transistors, power plants, motors, power supply systems, and more. Since control relays play an integral role in all electrical systems, developers have created different types of control relays in varying sizes, shapes, and specifications. Monitoring, general-purpose, safety relays, and latching relays are some of the many types available in the market. Below are some of the advantages of electromagnet relays-

  • Control relays have fast reset and fast operations.
  • They can be used for both DC and AC for protection.
  • They are highly efficient, reliable, and compact.
  • Control relays can enable control stations to send individual control signals to remotely located components or located systems.
  • Control relays carry high resistance to voltage transients and also enable circuit multiplication.
  • Relays combine high performance and value with cost-efficiency by offering functions like space-saving housing.
  • Control relays can be easily installed and do not require a lot of maintenance.

The field of electronics is diverse and multi-layered. A person can’t possibly know about all the essential components that go into the smooth functioning of an electrical device or equipment. Therefore, it is imperative to join hands with a leading electrical service provider, who will ensure that all your installations are carried out in a reliable and effective manner. In addition, in case of any emergency, they will guide you on how to diffuse the situation by immediately providing you with the most effective and dependable guidelines.
