Congratulations on the AOBO 7228 to obtain A-level certification of state grid

AOBO 7228 type modular is industrial Ethernet switch which is obtained A-level certification by the state power grid automation equipment Testing Center .

AOBO 7228 series of switches are unmanaged modularized Industrial Ethernet Switches, support a maximum of 4 Gigabit Ethernet interfaces and 24 Fast Ethernet interfaces which may be configured as optical ports or electrical ports.Customers may select suitable optical-electric module combination according to the actual demand on site. Support ABRing? full-distributed high self-healing loop technology, with the network self-healing time less than 5ms. This series of switches are specially developed for the adverse industrial operating environment and the products comply with the highest power level EMC and thunder-strike prevention standards. Support the specific concentrated ABNet automatic topology discovery, Web remote configuration management and relevant network management functions, such as the broadcast storm control, port rate limit, VLAN and QoS. The products are widely utilized in the wind power station industry,substation automation, highway, automatic control communication of municipal engineering.
