Moxa EDS-205A 5-Port Industrial Ethernet Switch with Redundant Power for Harsh Environments

The Moxa EDS-205A Series delivers reliable Layer 2 Ethernet connectivity for industrial control networks operating in harsh environments. This unmanaged switch provides 5 Fast Ethernet ports with auto-negotiation and auto MDI/MDI-X, eliminating manual configuration while ensuring plug-and-play deployment in factory automation, transportation infrastructure, and process control installations. Designed for mission-critical applications where network downtime translates to operational losses, the EDS-205A features redundant DC power inputs that automatically failover between two independent power sources. The compact DIN-rail form factor and wide operating voltage range (9.6-60 VDC) simplify integration into existing control panels and fieldbus cabinets. Available in standard (-10°C to 60°C) and wide-temperature (-40°C to 75°C) variants, with copper-only or fiber uplink configurations to match your network topology and distance requirements. Best For The EDS-205A serves industrial networking applications where environmental extremes, safety compliance, or constant vibration demand purpose-built Ethernet infrastructure: - Marine and offshore installations requiring DNV, LR, ABS, or NK type approvals for shipboard Ethernet networks connecting navigation systems, engine monitoring, and SCADA equipment - Railway wayside applications such as trackside signal control, platform surveillance networks, and station automation systems meeting EN 50121-4 electromagnetic compatibility requirements - Hazardous area networking in oil and gas facilities, chemical plants, and refineries where Class I Division 2, ATEX Zone 2, or IECEx certification is mandatory - Intelligent Transportation Systems (ITS) including traffic signal controllers, variable message signs, and roadside monitoring equipment complying with NEMA TS2 specifications - Factory automation networks connecting PLCs, HMIs, and I/O modules in manufacturing environments with extreme temperatures or exposure to electrical noise Key Features - Five 10/100BASE-TX auto-negotiating Ethernet ports with automatic MDI/MDI-X crossover detection eliminate the need for crossover cables - Store-and-forward switching architecture with 512 Kbit packet buffer and 1K MAC address table ensures reliable data delivery in broadcast-heavy networks - Redundant dual DC power inputs with automatic failover, reverse polarity protection, and 1.1A overcurrent protection prevent single-point power failures - DIP switch controls for broadcast storm protection and QoS prioritization allow field configuration without software tools - PROFINET Conformance Class A (CC-A) compliance on hardware version 3.0.0 and later enables integration into Siemens automation networks - LED indicators for power status and per-port link/activity provide at-a-glance diagnostics for troubleshooting - Compact 30 x 115 x 70 mm aluminum housing with IP30 rating fits standard DIN-rail mounts in crowded control cabinets - Wide operating voltage range (9.6-60 VDC) accommodates 12V, 24V, and 48V industrial power systems with single part number Quick Specs Ethernet Ports 5 × 10/100BASE-TX (RJ45) or 4 × RJ45 + 1 × 100BASE-FX fiber (SC/ST, multimode/single-mode) Switching Performance 1 Gbps switching fabric, 0.74 Mpps forwarding rate, 1K MAC address table Power Input Redundant dual inputs: 12/24/48 VDC (9.6-60 VDC) or 18-30 VAC (47-63 Hz), < 3W consumption Operating Temperature Standard models: -10°C to 60°C; Wide-temp (-T) models: -40°C to 75°C Humidity Tolerance 5% to 95% RH (non-condensing) Shock & Vibration IEC 60068-2-27 (shock), IEC 60068-2-6 (vibration), IEC 60068-2-31 (free fall) Electromagnetic Immunity IEC 61000-4-2 (ESD: ±6kV contact), IEC 61000-4-4 (EFT: 2kV power), IEC 61000-4-5 (Surge: 2kV) Housing & Mounting Aluminum, IP30 protection, DIN-rail or wall mount, 175g weight MTBF 3,316,504 hours (copper models), 3,045,679 hours (fiber models) per Telcordia standards Available Models EDS-205A (5×RJ45), EDS-205A-T (5×RJ45 wide-temp), EDS-205A-M-SC/ST (4×RJ45+1×MM fiber), EDS-205A-S-SC (4×RJ45+1×SM fiber), all with -T wide-temp variants What's Included - 1 × EDS-205A Series Ethernet switch (model-specific port configuration) - 1 × Quick Installation Guide
