• 16× Gigabit Copper Ports: Support 10M/250m long-distance Ethernet for flexible industrial deployments

• Auto-MDI/MDIX: Simplifies plug-and-play installation without crossover cables

2. Advanced Network Management & Performance

• Industrial-Grade Switching Chip: Delivers high backplane bandwidth & large cache to reduce congestion

• IEEE 802.3X Flow Control: Ensures jitter-free transmission for high-bitrate video & data

• MAC Address Auto-Learning/Updating: Optimizes network efficiency in dynamic industrial environments

3. Industrial-Grade Reliability & Protection

• 6KV Surge Protection: Safeguards ports & power against lightning & electrical surges

• Aluminum Alloy Housing: Enhances heat dissipation, EMI shielding, and rust resistance

• Dual 12-57V DC Power Inputs: Ensures 24/7 uptime with wide voltage tolerance

4. Rugged Design for Harsh Environments

• DIN-Rail Mounting (IP40): Compact & vibration-resistant for industrial cabinets

• -40°C to +75°C Operation: Withstands extreme outdoor/indoor conditions

• Fanless & Low-Power: Silent operation with minimal maintenance

Application Scenarios

1. Smart Transportation Systems

• Implements mission-critical communication networks for intelligent traffic management (ITS)

• Supports ERPS ring topology (<20ms failover) for uninterrupted railway signaling

• Withstands vibration and extreme temperatures (-40°C to +75°C) in tunnel surveillance deployments

2. Industrial Automation Networks

• Forms high-availability backbone for Industry 4.0 smart factories

• Enables deterministic Ethernet communication (<50ms via MSTP) for PLC/robot control

• Provides 6KV surge-protected ports for electrically noisy manufacturing environments

3. Energy Infrastructure

• Meets IEC 61850-3 standards for substation automation systems

• Facilitates long-distance fiber connectivity (120km) between power distribution units

• Dual DC power inputs (12-57V) ensure reliability in smart grid applications

4. Harsh Environment Deployments

• Operates reliably in mining/oil/gas facilities with IP40-rated aluminum housing

• Enables remote monitoring via fiber-optic links in offshore platforms

• Fanless design prevents dust accumulation in cement/steel plants

5. Urban Infrastructure

• Powers smart city applications with QoS-prioritized traffic (video, IoT, control data)

• Supports VLAN segmentation for secure traffic separation in metro networks

• DIN-rail mounting suits compact space installations in traffic control cabinets

Technical Superiority:

• Layer 2+ management with IPv4 static routing for flexible network design

• Industrial-grade components certified for 35-year MTBF reliability

• Jumbo frame support enables high-throughput data transmission

• Conformal coating protects against humidity and corrosive gases
