Industrial Ethernet Layer 3 Switches

Industrial Switches | Product Information The IE340 Series access switches provide network infrastructure to digitally transform industry.

Overview

Allied Telesis IE340 Series switches are the perfect solution for access connectivity in industrial automation and control networks.

Their low latency, high availability and high capacity enables seamless integration with industrial applications, supporting multiple transmission streams. They are hardened to withstand difficult environmental conditions, such as electromagnetic noise, wide-ranging temperatures, high humidity, and vibration.

The IE340 Series provides network infrastructure for many vertical markets and related applications, such as:

Building Automation

Facility management including security and access control, fire protection, energy management, heating/ventilation/air-conditioning, and lighting control.

Cranes & Logistics

Control of automated stacker cranes and other devices that boost the efficiency of dynamic warehouse environments.

Industrial automation and process control

Interconnection of machines, IoT devices, sensors, and more. Instant communication between systems and people enables improved efficiency and resilience in manufacturing environments.

Marine control and monitoring

Seamless communication for vessel, including high speed light water craft, and offshore units.

Railway transportation (signalling and telecommunications)

Control signaling and telecommunication for improved safety, risk management, operating efficiency, and signage.

Roadway transportation (traffic control)

Adaptive traffic control, telematics, and preventive maintenance.

Smart cities

Public space and urban infrastructure that provides safety and security, parking management, environmental metering, lighting, and information kiosks.

Wastewater treatment

Industrial sewage treatment plants for efficient and reliable water purification. Control systems ensure process optimization by intelligent control, regulation, and monitoring.

IT/OT convergence

Improve productivity and decisionmaking by integrating your operational technology (OT) and information technology (IT). Use the intelligence of Industry 4.0 to collect, analysis, and manage all your data in real time.

Network automation and orchestration

Powerful automation options include Allied Telesis Autonomous Management Framework Plus (AMF Plus) and open standard-based northbound API.

For easy integration into complex networks consisting of physical, virtual, and multi-vendor devices, the IE340 Series features:

NETCONF/RESTCONF + YANG data modelling for network automation.

OpenFlow v1.3 for Software Defined Networking (SDN) orchestration.
