The Moxa EDS-528E Series offers high-density 28-port managed Layer 2 Ethernet switching, designed for demanding industrial applications including transport, power, marine, and process control. With 24 Fast Ethernet and four combo Gigabit (RJ-45/SFP) ports, it provides flexible copper/fibre integration and uplink options.
Resilience features include Turbo Ring/Turbo Chain (sub-20 ms failover), STP/RSTP/MSTP, and MRP, making it ideal for ring or mesh topologies. Advanced traffic control is handled via VLAN (802.1Q), quality of service, IGMPv1/v2/v3 snooping, port trunking, and bandwidth management.
The EDS-528E supports EtherNet/IP, Modbus TCP, and PROFINET, while offering robust security: SNMPv3, RADIUS, TACACS+, MAC ACL, MAB authentication, and Sticky MAC protection. Management is available via web, CLI, SNMP, serial console, or ABC-02-USB for rapid backup/restore.
Hardware includes an IP30 metal housing, dual redundant DC or high-voltage AC/DC inputs, and wide operating temperature options from -40 to +75 °C. It meets IEC 61850-3, IEEE 1613, UL61010, EN 62368-1, marine (DNV), and EMC Class A certifications.
With a 16K MAC table, 2048 IGMP groups, and a 1 Mbit buffer, the EDS-528E is a robust choice for large-scale industrial networks requiring both density and reliability.
