MOXA EDR-810-2GSFP-T Industrial Secure Router – EDR-800 Series

MOXA EDR-810-2GSFP-T — Eight-Port Gigabit Secure Router with Dual SFP Fiber Uplinks for OT Network Segmentation

The EDR-810-2GSFP-T occupies a well-defined position in the OT security architecture: it is the boundary enforcement node between the field-device layer and the supervisory network. Equipped with eight 10/100/1000BASE-T copper ports and two 100/1000BASE-X SFP fiber uplinks, the unit consolidates stateful packet inspection, IPsec/OpenVPN tunnel termination, IEEE 802.1Q VLAN segmentation, and NAT/PAT address translation into a single DIN-rail chassis rated for continuous operation from -40°C to +75°C. In process automation and discrete manufacturing environments where PLC panels, RTUs, and HMI workstations must be isolated from corporate IT traffic without introducing additional rack space or separate firewall appliances, the EDR-810-2GSFP-T provides a deterministic, single-device solution that satisfies IEC 62443-4-2 Security Level 2 requirements out of the box.

The dual SFP slots accept standard 100/1000BASE-SX, -LX, or -ZX transceivers, enabling fiber backbone connections to SCADA hosts or aggregation switches at distances from 550 m (multimode) up to 80 km (single-mode ZX), effectively eliminating ground-loop interference and EMI coupling that copper uplinks introduce in high-voltage switchgear environments. Redundant 12–48 VDC power inputs with independent fusing ensure that a single power rail failure does not interrupt the security perimeter — a non-negotiable requirement in IEC 61511 functional safety loops where the communication path is part of the safety instrumented system (SIS) diagnostic channel.

Technical Parameters

Hardware Logical Analysis

The EDR-810-2GSFP-T is built on a purpose-designed OT security ASIC rather than a repurposed IT router chipset. This distinction has measurable consequences for field deployments. The internal switching fabric handles Layer 2 forwarding at wire speed across all eight copper ports simultaneously, while the security processing engine — implemented in a dedicated hardware accelerator — performs AES-256 encryption and SPI firewall lookups without borrowing CPU cycles from the routing and management plane. The result is a consistent, bounded latency profile: firewall-inspected throughput does not degrade under sustained traffic load, which is critical when the router sits inline with a PROFINET or EtherNet/IP real-time control network where jitter above 1 ms can trigger watchdog faults in the PLC.

EMC and Signal Integrity: The chassis passes IEC 61000-4-2 (ESD ±8 kV contact / ±15 kV air), IEC 61000-4-4 (EFT ±4 kV), and IEC 61000-4-5 (surge ±2 kV line-to-earth) without requiring external surge suppressors. Internal common-mode chokes on each RJ45 port suppress differential noise injected by variable-frequency drives (VFDs) and servo amplifiers operating in the same cabinet. The SFP fiber uplinks provide galvanic isolation by design, breaking the ground reference between the field network and the control room backbone — a topology that eliminates the most common source of communication errors in high-voltage switchgear panels.

Thermal Management: The fanless convection-cooling design eliminates the single most common mechanical failure mode in industrial electronics. The aluminum extrusion housing acts as a heat spreader, maintaining junction temperatures within specification across the full -40 to +75°C ambient range without derating. This is validated by MOXA’s burn-in test protocol: each unit undergoes 48-hour thermal cycling between -40°C and +75°C before shipment.

Redundant Power Arbitration: The dual power inputs use a diode-OR circuit with active balancing. When both supplies are present, the higher-voltage input carries the load; if it drops below threshold, the secondary input assumes full load within < 20 ms — faster than the watchdog timeout of any major PLC platform. The input range of 12–48 VDC accommodates both 24 VDC PLC panel rails and 48 VDC telecom battery-backed supplies without a DC-DC converter.

System Integration Benefits

• IEC 62443-4-2 SL2 Compliance Out of the Box: The unit ships with a pre-hardened firmware configuration that satisfies Security Level 2 component requirements, reducing the documentation burden for ISA/IEC 62443 system certification audits in energy, water, and rail sectors.
• Zero-Impact Inline Deployment: The transparent firewall mode allows the EDR-810-2GSFP-T to be inserted into an existing network segment without IP address changes on any connected device — critical for brownfield retrofits where re-addressing PLCs and HMIs is operationally prohibited.
• Deterministic Latency Under Load: Hardware-accelerated SPI and AES processing maintain sub-millisecond forwarding latency at full firewall throughput, preserving the timing integrity of PROFINET IRT, EtherNet/IP, and Modbus TCP polling cycles.
• Granular VLAN Segmentation: IEEE 802.1Q support enables engineers to isolate PLC networks, HMI workstations, historian servers, and engineering workstations into separate broadcast domains on a single physical infrastructure, reducing the attack surface without additional hardware.
• Encrypted Remote Access: IPsec IKEv2 and OpenVPN tunnel termination allows maintenance engineers to access field devices securely from remote locations without exposing PLC programming ports to the corporate WAN — a direct mitigation for MITRE ATT&CK ICS technique T0886 (Remote Services).
• Syslog and SNMP v3 Diagnostic Transparency: All firewall events, VPN tunnel state changes, and port link events are forwarded in real time to a central SIEM or NMS (PRTG, Zabbix, SolarWinds), providing the audit trail required by NERC CIP-007 and IEC 62443-3-3 SR 6.2.
• Redundant Power for High-Availability Loops: Dual 12–48 VDC inputs with < 20 ms switchover time ensure the security perimeter remains active during planned maintenance on one power rail, supporting SIL 2 diagnostic coverage requirements where the communication path is monitored.
• MOXA MXview Integration: Native SNMP MIB support and MOXA MXview topology discovery allow the EDR-810-2GSFP-T to appear as a managed node in the network visualization dashboard alongside MOXA EDS and PT series switches, providing a unified operational view without a separate management console.
• Wide-Temperature Reliability for Outdoor Cabinets: The -40 to +75°C rating covers unheated outdoor enclosures in northern climates and direct-sun-exposed cabinets in tropical environments, eliminating the need for cabinet heaters or air conditioners that add cost and maintenance overhead.
• DIN Rail Form Factor for Panel Integration: The 54 mm wide DIN rail profile fits standard 35 mm EN 50022 rails alongside PLCs, I/O modules, and power supplies, keeping the security device within the same panel rather than requiring a separate IT rack.
