What is an industrial switch?
Industrial switches are also called industrial Ethernet switches. At the beginning of the design of ordinary Ethernet, the application requirements of industrial networks were not taken into account. Therefore, when the network equipment is deployed on an industrial site, the stability of ordinary commercial switches will face great challenges in the face of harsh working environments and severe electromagnetic interference. In response, industrial Ethernet switches with high reliability, stability and security have emerged as the times require, and have become a transmission tool that can adapt to complex industrial environments and facilitate industrial automation network deployment.
As the industrial switch can withstand harsh working environment, rich product series and flexible port configuration, it can meet the needs of various industrial fields. With the rapid development of power, metallurgy, petrochemical, environmental protection, transportation, construction and other industries, the demand for industrial Ethernet switches for information construction in various industries is also increasing.
The Main Advantages of Industrial Switch
1.Use industrial-grade components
Industrial switches have high requirements for the selection of components and must withstand the detection of harsh environments, so it can well adapt to industrial-grade environments and support industrial applications in a variety of harsh environments.
2.Fast ring network and fast redundancy
Industrial switches generally have fast ring network and fast redundancy functions, and the system redundancy time can be less than 50ms. Although commercial products can also form redundant networks, the self-healing time is more than 10-30 seconds, which cannot meet the requirements of industrial environments. For example, the self-healing time of an industrial ring network switch developed by Utop is at least 20ms.
3.Super anti-interference performance
Industrial-grade switches is with strong anti-interference performance, can work in harsh electromagnetic environments, and have high protection levels in terms of lightning protection, water resistance, corrosion resistance, impact resistance, and anti-static. However, commerical grade switch don’t have these characteristics. For example, UnitekFiber 8-port POE full Gigabit industrial switch has 6KV lightning protection, industrial level 4 protection and anti-interference ability.
4. Adapt to a wide temperature environment
Industrial switches generally use a pleated metal case, which has better heat dissipation and stronger protection. It can work normally in the temperature range of -40℃ to + 75℃ and can adapt to complex temperatures and humidity. Commercial switch products can only work in the range of 0℃-+ 50℃, which cannot meet the working requirements in harsh weather environments.
5.Redundant power supply design
Power supply is a very important part of industrial switches. Power failures generally account for more than 35% of equipment failure rates. To avoid trouble caused by power failures, industrial switches use a dual power redundancy design to ensure stable and reliable system operation. Commercial products generally use AC single power supply, which is not suitable for applications in industrial environments.
6, long life
Industrial switches use industrial-grade solutions from housing materials to supporting components, so the product has higher reliability, longer service life, and generally has a service life of> 10 years, while the service life of ordinary commercial switches is 3-5 years.
