Allied Telesis Industrial Ethernet Layer 3 Switch

Engineered for demanding industrial networks, the Allied Telesis IE340-12GT is a compact, high-performance Layer 3 managed switch designed to deliver reliable, secure connectivity in factory floors, distribution centers, and harsh environments. It blends rugged hardware with an advanced feature set and robust security to support critical automation and control applications with deterministic performance. The IE340-12GT is purpose-built for high-density deployments, offering flexible topology options and enterprise-grade management in an industrial package that can scale with your network.

• Rugged, reliable performance for harsh environments: Built to withstand the rigors of industrial settings, including temperature variations, dust, and vibration, the IE340-12GT delivers stable operation in 24/7 automation, process control, and data collection tasks. Its durable design minimizes downtime and maintenance while maintaining consistent throughput and reliability.
• Flexible port configuration for dense industrial topologies: The switch provides 8 x 10/100/1000T copper ports for direct connections to controllers, sensors, and other devices, paired with 4 x 100/1000X SFP uplinks for high-speed fiber links. This combination supports scalable, layered architectures with easy uplink to core networks, edge aggregation, or redundant paths, enabling resilient plant-floor networks.
• Deterministic performance with high-throughput hardware: A 24 Gbps switch fabric and a forwarding rate of 17.8 million packets per second empower real-time data flows, time-critical control traffic, and bursty industrial workloads. This throughput ensures low-latency responses for motion control, time-stamped telemetry, and safe, synchronized operations across multi-device deployments.
• Layer 3 routing and secure inter-VLAN segmentation: The IE340-12GT brings edge routing capabilities to the factory floor, enabling inter-VLAN routing, scalable segmentation, and efficient policy enforcement. Built-in security features help protect control networks from unauthorized access and reduce exposure to common threats in industrial environments, while keeping essential control channels isolated and performant.
• Comprehensive management, scalability, and reliability: Designed for growing networks, the switch supports a large MAC address table (16K entries) to accommodate sizable device inventories and access control policies. With standard management interfaces and centralized monitoring options, you can deploy, configure, and manage the IE340-12GT across multiple sites from a single console, ensuring consistent policy enforcement and operational visibility.
