What technical standards must industrial grade switches meet
We all know that industrial switches are designed specifically for industrial environments, so the requirements for industrial switches are much stricter than those for general commercial switches! But now many in the market are selling commercial grade switches under the guise of industrial grade switches, because many customers cannot distinguish them. Once a problem occurs, not only is it troublesome to repair, but more importantly, it affects the normal operation of the project! So it is beneficial and harmless to have a certain understanding of industrial switches! Next, let's take a look at the standards that a truly industrial grade switch must meet, let's take a look together!
Among the numerous performance indicators of industrial grade switches, operating temperature, lightning protection level, shock and dust prevention, safety standards, stability performance, and material selection are very important. In addition, in terms of fast redundancy, anti-interference, temperature characteristics, power supply, etc., careful assessment is also necessary!
1. Fast redundancy
Industrial Ethernet switches can form a fast redundant network, using Advantech's original X-Ring protocol to build a reliable industrial network for you, with an ultra fast self-healing time of less than 10 milliseconds.
Commercial products can also form redundant networks, but the STP protocol needs to be activated, so the redundant time can reach 10-30 seconds or more, so it cannot be used in industrial environments.
2. Anti strong interference - suitable for harsh environments
Ethernet products can work in harsh electromagnetic environments and have high protection levels in data port lightning protection, fast pulse burst, static electricity, etc., which commercial products do not have.
3. Good temperature characteristics and installation flexibility
The industrial Ethernet switch with good temperature characteristics and positive dimensional communication is designed for wide temperature range. Working temperature: -40~75 ℃ Storage temperature: -40~85 ℃, meeting the stability requirements in harsh weather environments. The installation method is more flexible, and industrial grade products can support various methods such as rail installation, panel installation, stacked installation, and cabinet installation.
4. Advantages in power supply and installation methods
The power supply part of industrial Ethernet switches is the root cause of any product, and the proportion of power failures in all products is over 35%. So industrial switch products generally choose a dual power supply mode to avoid trouble caused by power failure. And it adopts DC power supply. Commercial products generally use AC single power supply.
