The classification of switches is very complicated, and it takes four years to learn. I found all kinds of switch categories, but there seems to be no industrial switch. The only thing is that there are well-known industrial switches, commercial switches and other types of switches. The so-called industrial switches and commercial switches are both used for Ethernet and Internet applications. Industrial switches are industrial PCs, or variant devices of PCs, which are mainly used to run special corresponding programs.
Maybe I don't know much about it. The following is the switch difference I know to answer the questioner.
What's the difference between an industrial switch and a commercial switch?
In short, industrial switches have strong compatibility (PLC, switches and other industrial products) and can adapt to harsh environments. What are the specific aspects?
Industrial switches are divided into network management and non-network management, and have various output interfaces (4, 5, 8, 16, 24, etc. ) depending on the quantity, and the prices of different functions and interfaces are different. General industrial switch can provide three working modes, supporting "standard mode", "VLAN isolation" and "network cloning", and can form various application scenarios such as security monitoring system, wireless networking and diskless startup.
First, it has strong protection ability, generally requiring its IP grade to be IP40. Industrial switches have special protective coating and good anti-interference ability, and are waterproof, anti-corrosive, lightning-proof and anti-static (among them, power surge protection, network port surge protection and electrostatic interference must comply with IEC6 1000-4-5 and 6 1000-4-).
Secondly, the work stability is strong. The electronic components used in industrial switches are all designed and strictly selected, including fuses, power chips, surge absorbers, patch resistors and capacitors, electrolytic capacitors and assembled PCM boards, so they can operate stably in harsh environments. Industrial switches all adopt redundant power supply design (redundant power supply is a kind of power supply used in servers, which consists of two identical power supplies, and the chip controls the power supply to balance the load. When one power supply fails, another power supply can take over its work immediately, without delay in the process of replacing the power supply), so it can ensure the long-term and stable operation of the switch.
Third, it has a longer service life. The service life of industrial switches is generally more than 10 years, while the service life of ordinary commercial switches is generally 3~5 years.
Fourthly, it can work in a wide temperature range. Industrial switch has a special metal shell, which has good heat dissipation performance and can work normally in the temperature range of -30 to +75.
Fifth, an optical fiber ring network can be formed. Industrial switches all adopt redundant links, which can make the reliability and stability of optical fiber ring network good. The failure recovery time is only 10 ~ 20ms, but the failure recovery time of ordinary commercial switches will be delayed, which is about 10~30 seconds, which is not a grade.
As we all know, Ethernet switches are generally divided into: commercial (Ethernet) switches, industrial (Ethernet) switches and home (Ethernet) switches. Because we are a professional manufacturer of industrial switches, we will focus on industrial switches here.
Industrial switches are generally used in industrial production occasions, and usually have a variety of appearances and installation forms. According to different applications, it is required to be waterproof, dustproof, earthquake-resistant and electromagnetic interference-resistant. Of course, it also requires high reliability, and it also needs long-term operation without interruption for 24 hours. Some automatic control applications require low forwarding delay, some require redundant power supply, DC24V power supply and so on. I believe everyone has heard of the name of an industrial switch, that is, an industrial switch. So, what's the difference between industrial switches and industrial switches? Let me give you a brief introduction.
In fact, industrial control switch is not a standard name, commonly known as it. Switches used in industrial control industry are often industrial switches. Generally speaking, it is an industrial computer, a program-controlled switch and a switch. These are three things. Industrial computer is actually an industrial PC, or a variant of PC, which is mainly used to run special corresponding programs. Program-controlled exchange, this is very simple, that is, telephone exchange, which the company needs to install switchboard and extension.
Of course, the switch is for PC. Ethernet is a standard network protocol, and the networks we use now are all Ethernet structures, so the switch we are talking about and the Ethernet switch are the same thing, and they are generally not called that. As for industrial switches, it should be a network management switch different from home. In fact, this kind of product is not so clearly defined. Now there are only two 300 switches for network management, so there is no problem for home use.
The other is working hours, which are generally supported by the industry, but now household equipment is often never powered off, so there is no need to distinguish clearly.
In fact, there is no such thing as an industrial switch. In fact, it is an industrial computer, which is an industrial computer. Industrial switch is a switching device used in industrial control field and security industry.
Well, the above content is a very high-tech introduction about the difference between industrial switches and industrial switches, hoping to help everyone!
