IoT Actuator-Relay

summarize

A relay is a switch which can control other devices through electrical signals. Relay plays a very important role in IoT because it can be used to control a switch remotely through the internet, which means that you can control a certain switch through the internet at any time and from any place.

For example, you can use IoT apps to remotely control your home's doorbell, phone, TV, fan, pump, heater, or other household items. In addition, it can be used in smart factories, robotics, node control, remote monitoring, and many other scenarios. Therefore, relays can achieve ubiquitous control functions in the Internet of Things, making it smarter and more convenient.

• The development of the relay began in 1832 when it was designed by James Brindley, an English inventor. Branson's aim was to have better control over sluices. He invented a device that enabled the sluice gates to open or close, and this was the earliest relay.
• With the progress of industrialization, people began to use relays to control a variety of different mechanical devices. 1876, the German physicist Constantine Thiel invented a device capable of controlling mechanical switches by means of an electric current, which was a key invention in the development of relays.
• Subsequently, relays began to be used in automated factories. 1913 was an important step in the development of relays when French physicist Marcel Ellis invented a device capable of operating multiple mechanical devices while transmitting data.
• In the 1950s, relays began to shift from mechanical devices to electronic devices with the development of semiconductor materials, and at that time relays also began to use transistors. Since then, newer components such as integrated circuits, microprocessors, and optical relays have been invented to further improve the function of relays.
• So far, a large number of relays with different functions have been invented and are widely used in homes, factories, hospitals and aerospace. Nowadays, relays have the advantages of good reliability, durability, small size and powerful functions, which play an important role in industrial production.

categorization

A relay is a device that can control current, voltage, power, speed and direction.

Based on their operating principles, relays can be categorized into interference relays, integrated relays, optically coupled relays, isolated converters, transistor breakdown switches, MOSFET breakdown switches, JFET breakdown switches and IGBT breakdown switches.

According to the driving method, the interference relay can be divided into direct drive interference relay, indirect drive interference relay, integrated drive interference relay, semiconductor optical coupling relay.

Depending on their operating voltage, relays can be categorized as high/low voltage relays, IF/UF relays, pulse relays, low temperature relays and high temperature relays.

Based on the shape, relays can be categorized into three types: plug type (without case), package type (with case), and integrated type (SMD).

application scenario

Relays were first used by people to remotely control large mechanical equipment, such as railroad signaling systems. As its reliability improved, it was also used in a wide variety of industrial, transportation, safety and energy applications. For example, the pneumatic brakes used in airplanes are a typical relay application. When an airplane lands, the pilot presses the brake release, which opens a pneumatic switch that activates the brakes, ultimately landing the plane safely.

A relay is a switch that can control a high current and is often used in automobiles, home appliances, industrial machinery, and other applications. It usually has one or more input ports that can be controlled to turn a high current on or off.

Common relay applications include automotive ignition, circuit breakers in home appliances, and fans, pumps, and gates in industrial machinery. For example, automotive ignition is driven by a relay that controls the ignition device inside the vehicle, while circuit breakers in household appliances monitor household voltage and disconnect power when an overload or other abnormal condition occurs. In addition, fans, pumps, and gates in industrial machinery can be driven by one or more relays for more precise control.

growing trend

Relay as an intelligent component has a wide range of applications. The market share of relays is expected to increase significantly in the next 10 years. With the development and growth of 5G, Internet of Things, artificial intelligence, big data and other emerging technologies, "interconnection" and "integration" has become the direction of the development of the current era, because the development of relays will have more opportunities.

• First, relays will continue to play an important role in the future, with a wide range of applications in smart homes, automotive, and industrial automation. With the development of the Internet of Things (IoT), big data, and artificial intelligence, relays will be used in IoT sensors, real-time monitoring, remote control, robotics, and other emerging applications that enable kinematics to be successfully realized.
• In addition, future relays will continue to improve their performance in favor of more complex applications. For example, relays currently on the market, which are mostly made of metal and quartz, will be improved in the future so that they can be used in more complex environments. At the same time, new types of relays will be developed that are small in size, low in power consumption, low in cost, and easy to install.
• Finally, with the development of chip technology, miniature relays will also be effectively developed, making relays smaller in size and power consumption and becoming the first choice for more applications. A large number of new types of relays will appear in the future, thus enriching the relay market.

In conclusion, relays, as an intelligent component, have a wide range of application prospects. It is expected that in the next 10 years, relays will be influenced by new technologies, continuously improve their performance, develop a variety of new products, and be widely used in various fields.
