DST-MSW-28G-RA Series

Classification:

Network Managed Industrial Ethernet Switch

The DST-MSW-28G-RA series gigabit network management rack-mounted industrial Ethernet switches meet IEC61850-3 standards and conform to the national network A- level standards. They support up to 24 100 megabit/gigabit ports and can be configured with 28 gigabit SFP modules. It has complete management functions, including QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP V1/V2/V3, RSTP/STP, etc. The unique RingGo redundant ring network protocol, the network link switching and recovery time is less than 20ms, which improves the reliability of the network. Redundant power input, wide temperature design, strong anti-electromagnetic interference ability, especially suitable for extremely strict requirements such as digital substations and other applications.

Keywords: Isolator

    Installation method

    The default is rail type, R: rack type; 3R: three-layer rack type; RA: State Grid Class A standard rack type; P:POE function;

    Remarks

    Guide rail type default 24VDC dual power supply; Rack type and three-layer rack type default AC/DC110 ~ 220V single power supply; State Grid Class A default AC/DC110 ~ 220V dual power supply; With POE function default 48V single power supply;
    Under non-default conditions: AC/DC110 ~ 220V single power supply can be selected for some models of rail-type switches, and the suffix of the model needs to be added: -220V;
