What Are The Advantages In The Use Of Industrial Grade Switches
Industrial switch, also known as industrial Ethernet switch, is the Ethernet switch equipment used in industrial control field. With the popularization of IP technology in traffic monitoring system, intelligent networked traffic management system emerges as the times require, and industrial grade intelligent Poe switch is also widely used.
Poe only needs to install and support a single cable, simple and space saving, and the device can be moved at will (simple, convenient for use). Save costs. Many live devices, such as video surveillance cameras, need to be installed in places where it is difficult to deploy AC power sources so that they do not need expensive power sources and the time required to install them, thus saving costs and time.
Industrial grade switches have the following advantages:
Industrial switch products can form a fast redundant network and use industrial grade switches with self healing time of less than 10 milliseconds.
Commercial products can also form redundant networks, but need to start the STP protocol so that the redundant self - surplus time will reach 10~~30 seconds, above, so it can not be used in the industrial environment.
2, anti disturbance - suitable for harsh environment
Industrial grade switches can operate in harsh electromagnetic environments and have a high level of protection against lightning, fast pulses and static electricity at data ports, which are not available for commercial use.
3, good temperature characteristics & installation flexibility
The industrial grade switch has good temperature characteristic, and the industrial grade switch is designed with wide temperature. Working temperature: -45 ~ 75 ℃ storage temperature: -45 ~ 85 ℃. The Poe switch has af standard and a higher power supply power than at standard than af. In general, the at standard is compatible with af standard. It is better to support the at standard.
Poe power supply equipment will only supply the equipment that needs to supply power. Only when connected to the power supply device can the Ethernet cable have voltage, thus eliminating the risk of leakage on the line. (security)
