Industrial Video Ethernet Switch 4x100M Ethernet 1 Video 1 RS485 1 Gigabit Fiber

Industrial Video Ethernet Switch 4x100M Ethernet 1 Video 1 RS485 1 Gigabit Fiber

Product Overview:

The LNK-GY4E1V1D Industrial Video Ethernet Switch is a rugged, physically isolated networking solution designed for harsh industrial environments. It integrates 4×10/100M Ethernet ports, 1×Video interface, 1×RS485 serial data port, and 1×Gigabit fiber uplink, making it ideal for multi-protocol industrial networks.

Key Features & Benefits

✅ Multi-Protocol Industrial Connectivity

• 4× Physically Isolated 10/100M Ethernet Ports: Ensures secure, independent network segments for internal & public networks.

• 1× Video Interface: Supports CCTV/IP camera integration for surveillance networks.

• 1× RS485 Serial Port: Enables PLC/SCADA device communication (MODBUS RTU, PROFIBUS).

• 1× Gigabit Fiber Uplink (1000BASE-X): Extends long-distance fiber backhaul (up to 120km).

✅ Industrial-Grade Reliability

• Physical Isolation Technology: Prevents cross-network interference for mission-critical systems.

• Wide Temperature Range (-40°C to 75°C): Operates in extreme outdoor/industrial conditions.

• IP40 Metal Housing: Resists dust, vibration, and EMI interference.

✅ Flexible Deployment

• DSLAM Bandwidth Expansion: Upgrades legacy fiber networks without rewiring.

• Multi-Network Isolation: Ideal for secure OT/IT network convergence.

• Plug-and-Play Installation: No complex configuration required.

Product Features:

1. High-Performance Data Transmission

• 1536 Bytes Jumbo Frame Support: Optimizes throughput for video & large data packets

• 1MB Built-in Frame Buffer: Prevents packet loss during high-traffic bursts

• Auto-Select Switching Modes: Store-and-Forward (error checking) or Cut-Through (low latency <5μs)

2. Intelligent Ethernet & Video Integration

• 4×10/100M Auto-Negotiation Ports: Support Full/Half-Duplex & Auto-MDI/MDIX for plug-and-play cabling

• 1024 MAC Address Table: Enables automatic learning/updating for large-scale device networks

• Video Interface: Directly connects CCTV/ANPR cameras without extra converters

3. Industrial-Grade Reliability

• 6KV Lightning & Surge Protection: Safeguards against power surges in outdoor installations

• Dual 12-48VDC Power Inputs: Ensures 24/7 uptime with redundant PSU support

• Wide Temp Range (-40°C to 85°C): Operates in extreme environments (factories, tunnels, substations)

4. Flexible Deployment & Monitoring

• DSLAM Bandwidth Expansion: Upgrades legacy fiber networks without cable replacement

• LED Port Status Indicators: Real-time monitoring of link/activity/speed per port

• DIN-Rail/Wall-Mount (IP40): Compact metal housing for space-constrained cabinets

Application Scenarios

1. Industrial Surveillance Systems

• Integrates IP cameras (Video port), Ethernet devices, and RS485 sensors into unified monitoring networks

• Enables real-time video analytics with low-latency (<5μs) data transmission

• Ideal for smart factory security and hazardous area monitoring

2. Transportation Infrastructure

• Powers railway/tunnel communication systems with electrical isolation protection

• Combines CCTV feeds (Video), signal controls (RS485), and Ethernet data in EN 50155-compliant networks

• Withstands vibration and extreme temperatures (-40°C to 85°C) in rolling stock applications

3. Energy & Utility Networks

• Connects substation SCADA systems via RS485 MODBUS and fiber-optic backhaul

• Provides surge-protected (6kV) communication for smart grid equipment

• Meets IEC 61850-3 standards for power automation systems

4. Smart City Deployments

• Aggregates traffic cameras (Video), IoT sensors (RS485), and Ethernet devices at roadside cabinets

• Supports DSLAM bandwidth expansion without fiber cable replacement

• IP40-rated for outdoor kiosk installations in harsh weather conditions

5. Oil/Gas & Mining Operations

• Creates explosion-proof networks with physically isolated ports

• Transmits video surveillance and equipment telemetry (RS485) via intrinsically safe fiber links

• Dual DC power inputs ensure reliability in remote field locations

Technical Superiority:

• Protocol transparency for video (ONVIF), data (MODBUS), and Ethernet (IEEE 802.3)

• Deterministic latency for time-sensitive industrial protocols

• Conformal coating protects against humidity and corrosive gases

• Auto-failover via redundant power inputs (12-48VDC)
