Moxa EDS-505A-SS-SC-T ,3 10/100BaseT(X) ports,-40 to 75C

The Moxa EDS-505A-SS-SC-T is a rugged, managed Ethernet switch featuring three 10/100BaseT(X) RJ45 ports and two 100BaseFX single-mode fiber ports with SC connectors. Designed for extreme environments, it operates reliably from -40 to +75 °C. Its powerful redundancy, security, and management features make it ideal for industrial network infrastructure.

It supports Turbo Ring and Turbo Chain with recovery times under 20 ms, as well as STP, RSTP, and MSTP. The switch includes VLAN, QoS, IGMP snooping, LACP, and port trunking for scalable network architecture. Full SNMP and IPv6 support enable comprehensive monitoring and control.

With advanced security features such as TACACS+, RADIUS, HTTPS, SSH, port lock, and broadcast storm protection, the device safeguards your network. It supports EtherNet/IP, Modbus TCP, and is PROFINET compatible. Designed for industrial strength, the unit includes IP30 protection, a metal housing, DIN-rail mount, and dual redundant power inputs.
