The Moxa EDS-508A Series features industrial-grade 8-port managed Ethernet switches built for high-performance networking in automation, surveillance, and harsh industrial environments. Equipped with Turbo Ring and Turbo Chain technologies, these switches deliver ultra-fast recovery times of under 20 ms for up to 250 switches. Additional redundancy is provided via STP, RSTP, and MSTP.

With strong security features including TACACS+, SNMPv3, IEEE 802.1X, HTTPS, SSH, and MAC-based port locking, the EDS-508A ensures secure network access. Management options include web browser, CLI, Telnet, serial console, Windows utility, and ABC-01. They are also compatible with MXstudio for intuitive visual network management.

Support for industrial protocols such as PROFINET, EtherNet/IP, and Modbus TCP ensures smooth integration into automation systems. VLAN, QoS, IGMP snooping, port trunking, bandwidth control, and alerting via email or relay output make these switches ideal for professional deployment.
