Security and manageability are enhanced through TPM 2.0, enabling hardware-level security, secure boot, and device authentication — essential for industrial and IoT deployments.
Typical Application Areas
The versatility and network connectivity of the LEX 3I140DW make it suitable for a wide range of industrial and embedded use cases, including:
- Industrial Network Gateway & Protocol Aggregation: The five independent 2.5GbE ports allow the LEX 3I140DW to act as a high-performance industrial network gateway, connecting multiple machines, sensors, and production lines to higher-level IT or cloud systems. Each port can be dedicated to a separate subnet, improving network segmentation, security, and reliability in factory and process automation environments.
- Edge Firewall, Router & Network Appliance: With five high-speed Ethernet interfaces, the LEX 3I140DW is ideally suited for industrial firewalls, routers, and secure network appliances. Typical deployments include WAN, LAN, DMZ, and multiple internal networks, enabling advanced traffic management, intrusion detection, VPN services, and network isolation at the edge.
- Machine Vision & Multi-Camera Systems: Many industrial cameras and vision sensors rely on GigE or 2.5GbE connectivity. The 5 LAN ports allow direct connection of several high-resolution cameras, reducing latency and eliminating the need for external switches. This makes the platform ideal for inspection, quality control, and automated optical inspection (AOI).
- Smart Factory & Industry 4.0 Edge Controller: In smart manufacturing environments, multiple Ethernet ports enable simultaneous connections to PLCs, robots, HMIs, SCADA systems, and MES platforms. The LEX 3I140DW can process and filter data locally while securely forwarding relevant information to central systems, improving real-time responsiveness and reducing network congestion.
- Transportation & Intelligent Traffic Systems: For roadside units, rail systems, and transport control cabinets, the five LAN ports support separate connections to cameras, sensors, signalling systems, and backhaul networks. This enables reliable data acquisition and real-time decision-making for intelligent traffic management and transportation monitoring applications.
- Network Video Recording (NVR) & Surveillance Systems: With five 2.5GbE ports, the board can support multiple IP cameras across dedicated networks, increasing throughput and reliability for industrial and commercial surveillance systems. This configuration helps maintain stable video streams while supporting analytics and recording at the edge.
