Overview
The Moxa EDS-G516E is a 16-port full-Gigabit managed Ethernet switch purpose-built for industrial automation environments where network uptime is non-negotiable. Its hardware-based Turbo Ring v2 redundancy recovers from a single ring break in under 20 milliseconds — fast enough to sustain PROFINET RT and EtherNet/IP implicit messaging without controller fault. The combination of 16 copper Gigabit ports and two combo SFP slots gives system architects the flexibility to build fiber backbone rings while keeping copper drops to each PLC and drive panel.
Rated for −40°C to +75°C with no fans, the EDS-G516E is designed for direct mounting inside electrical enclosures alongside PLCs and power supplies. Dual isolated power inputs (12–48 V DC) eliminate single-point power failures and accommodate both 24 V DC control power and 48 V DC UPS battery buses. Moxa's VLAN-based traffic segmentation allows engineers to isolate PROFINET device traffic from HMI and historian traffic on the same physical cable plant — reducing jitter and improving security.
Management via Moxa's MXview One network management platform provides topology discovery, LLDP/EtherNet/IP device mapping, and real-time bandwidth utilisation graphs. SNMP v1/v2c/v3, RMON, and syslog integration slot the EDS-G516E into enterprise network operations centres, bridging the IT/OT divide with familiar tools while preserving the determinism industrial protocols require.
Key Features
- Turbo Ring v2 — <20 ms Recovery — Hardware-accelerated ring redundancy bypasses spanning-tree delays. When a link or switch fails, Turbo Ring v2 reroutes traffic in under 20 ms, keeping PROFINET RT cycle times intact. Supports up to 250 switches per ring. Compatible with ITU-T G.8032 Ethernet Ring Protection (ERP) for interoperability with third-party switches.
- PROFINET-Aware Traffic Prioritisation — IEEE 802.1p/Q VLAN tagging with 4 hardware priority queues ensures PROFINET RT frames (class 2) receive deterministic forwarding ahead of best-effort traffic. MXview One auto-discovers PROFINET devices via DCP protocol, labeling each node on a graphical network map.
- Fanless −40°C to +75°C Design — Solid-state convection cooling eliminates moving parts and MTBF-limiting fan failures. The industrial-grade electrolytic-free design meets IEC 61850-3 for substation environments and EN 50155 for rail-side installations, suitable for outdoor cabinets and Arctic installations.
- Dual Isolated DC Inputs with Alarm Relay — Each power input is independently isolated, accepting 12–48 V DC. A dry-contact relay output triggers when power fails on either input or when the switch detects a ring break — enabling direct PLC fault input wiring without additional I/O modules.
