Anonymous users2024-02-07The difference between an industrial Ethernet switch and a commercial Ethernet switch.
1. The industrial Ethernet Jiaosuixin replacement machine is basically the same as the commercial switch in terms of data exchange function, but in terms of design and selection of components, the strength and applicability of the product can better meet the needs of the industrial site.
2. In addition, it is more flexible than commercial switches in terms of module expansion: there are a variety of optical ports and electrical ports for selection. In terms of material selection, product strength, applicability, real-time, interoperability, reliability, anti-interference and intrinsic safety, it can meet the needs of industrial sites.
3. Industrial-grade design generally meets the following requirements in design: industrial wide temperature design, 4-level guess wheel electromagnetic compatibility design, and redundant AC and DC power input. In addition, PCB boards are generally treated with "three proofs".
The general working temperature of industrial-grade products is -45 to 85 degrees, the humidity is 5-95 degrees, the temperature adaptation range is wide, and the protection level is high, so the industrial switch can be used in various harsh environments. The working stability of ordinary switches is generally about 0-45 degrees, and the humidity is:
Around 10-70 degrees, the adaptability of temperature and humidity is poor, and the protection level is also low, so it can only be used in ordinary civilian environments.
Industrial-grade equipment is generally designed to meet the needs of the industrial field, with a wide temperature design, high protection level, which can adapt to a variety of harsh and complex working environments and provide cost-effective Ethernet communication. Ordinary switches cannot be used in the industrial field, and can only be used in a simple civilian environment, and their adaptability is far less than that of industrial products.
Design up the difference.
The industrial switch adopts a redundant dual power input design, which can meet the requirements of high reliability, support card rail installation, and can adapt to the design and installation of the industrial field. Ordinary products use a single power input, which can easily cause power damage and communication interruption.
protection level to distinguish.
Industrial Ethernet switches will have anti-static protection, electromagnetic isolation protection, anti-surge protection and power isolation protection, etc., which can meet the design requirements of the industrial field, and the Ethernet communication is reliable and stable; However, ordinary switches generally do not have these protection functions and can only be used in simple environments.

Anonymous users2024-02-06Industrial-grade and network-level switches have the following wheel shifts to be closed
Different working environments: Industrial switches are suitable for harsh working environments, such as dark and humid, electromagnetic interference, etc., while network switches are relatively relaxed.
Different port configurations: The port configuration of industrial switches is flexible and can be configured according to different needs, while the port configuration of network switches is relatively fixed.
Different protection levels: Industrial switches have a higher protection level, such as IP65 or IP67, while network switches generally have an IP20 or IP30 protection level.
Different reliability: The industrial switch has high reliability and supports the ring network redundancy protocol, while the reliability of the network switch is relatively low.
Different functional characteristics: Industrial switches have a variety of functions, such as VLAN, QoS, etc., which can be configured according to different application scenarios, while network switches have relatively few functions.
Different: Industrial switches are relatively high, while network switches are cheaper.

Anonymous users2024-02-05Difference between industrial switch and commercial (normal) switch:
1. Appearance comparison:
Industrial switches use surface or pleated shells for heat dissipation, metal shells, and high strength. However, ordinary commercial switches have plastic shells with low strength, and the switches have fans for heat dissipation.
2. Ability to use the environment:
The working temperature of the industrial switch is -40 --85, and the dust and humidity adaptability is strong, and the protection level is IP40 or above. Therefore, industrial switches have a wide range of applications and are suitable for installation in various environments. The working temperature of commercial switches is 0 --50, and there is no dust and humidity adaptability, and the protection level is poor.
3. Service life:
Industrial switch service life》10 years. However, the service life of ordinary commercial switches is 3-5 years. Why look at the service life?
Because it is related to the later maintenance of the project. Therefore, in some cases where the use environment is relatively harsh and the data transmission requirements are stable, it is recommended to use industrial Ethernet switches.
4. Other reference indices.
Operating voltage: DC12V, DC24V, DC110V, DC AC220V for industrial switches. Commercial switches must operate at AC220V. The industrial switch mainly uses the ring network mode to reduce the cost of cable use and maintenance.

Anonymous users2024-02-03Industrial Ethernet switches are closer to industrial network communication, such as the interconnection of various fieldbuses, the redundancy of equipment, and the real-time nature of equipment requirements. In addition to the particularly harsh environment, the industrial environment also requires EMI electromagnetic compatibility, temperature, humidity, dustproof, etc., especially the temperature has the most extensive impact on industrial network equipment. Industrial Ethernet switches are closer to industrial network communication in terms of functions, such as interconnection with various fieldbuses, redundancy of equipment, and real-time equipment. The difference in performance is mainly reflected in the difference in adapting to the external environmental parameters.
In addition to many particularly harsh environments such as coal mines and ships, there are also environments with special requirements in EMI (electromagnetic compatibility), temperature, humidity and dust prevention. Among them, the influence of temperature on industrial network equipment is the most extensive.
Scold. The switch works in much the same way as the wire collector you are talking about. >>>More
The broadband network cable of the telecom is directly connected to the switch (if it is ADSL, it is also the same to connect the modem to the switch), and the host IP setting method for dial-up Internet access first: see the local connection in the network connection, click on the right health selection properties, and click the Internet Protocol (ICP IP) attribute before the icon in the notification area after the connection, and click to use the following IP address: IP address to fill in: >>>More
For example, a company has 4 customers to form a ring network, using optical cables to form a ring network of these four customers, customer 1--- customer 2--- customer 3--- customer 4--- customer 1, set to automatic conversion, when customer 1 --- customer 2 The optical fiber cable of this line is not connected, the ring network switch will automatically jump to customer 3 to supply the network to customer 2, so as to ensure that customer 2 can continue to access the Internet.
Domestic industrial switches. **Cheap. If it is used as a commercial switch, it is okay. If you are an industrial switch, you don't dare to compliment.
