Network switches are widely used in daily network construction. What is the difference between ordinary commercial switches that we often use and industrial switches? What is the special function? This article, share with you their differences.
Same basic functionality
There is no essential difference between the industrial switch itself and the commercial network in terms of the data link layer, network layer, protocol layer, etc., but for the real-time requirements of industrial control, industrial Ethernet solves the real-time communication, network security, intrinsic safety, and other requirements. Technical issues such as safety and explosion-proof technology, and some measures suitable for industrial environments, such as waterproofing, anti-vibration, etc., are not fundamentally different from commercial Ethernet at their core, which is the same as the difference between PCs and industrial computers.
Appearance difference
Industrial switches generally use a fanless casing fan mode and basically use a metal casing with grooves, which is relatively strong. Ordinary switches generally use a plastic casing or a thin smooth metal casing and use a fan to dissipate heat. model. This makes industrial switches better than ordinary switches in terms of waterproof, anti-fog, and moisture-proof performance.
Different use environment
The industrial switch adapts to a low temperature of 40°C to 85°C and has excellent dust and moisture resistance. The protection level is above IP40. The scope of use is relatively common, and it can be installed and used in harsh conditions. The working temperature of ordinary switches is generally between 0°C and 50°C. They basically have no dustproof and moisture-proof capabilities, the protection level is relatively poor, and they have POE power management functions.
The difference in service life
The service life of industrial exchanges is generally more than 10 years, while the service life of ordinary commercial switches is only 3 to 5 years. The service life is different, which is related to the maintenance in the middle of the project. For video transmission in network monitoring environments such as parking lots, and in those environments that require high-definition video output, industrial switches or switches whose performance needs to be comparable to industrial grades should be selected.
Different power supply modes
The voltage used by industrial switches is different from that of ordinary switches. Industrial switches can be limited to DC24V, DC110V, and AC220V, while ordinary switches can only work under AC220V voltage, and industrial switches are mainly in ring network mode. use and maintenance costs.
Summarize
The industrial switch is actually a switch specially designed to meet the flexible and changeable industrial environment and anti-interference. It is suitable for various industrial places and is an important electronic device in the industrial network.
