Industrial Applications

1. Harsh Environment Factory Automation

This switch is ideal for connecting Ethernet-based industrial control systems in factories where dust and extreme temperatures are common. Its -40 to 75°C operating temperature range and IP30 protection ensure reliable operation in non-condensing dusty environments, solving the challenge of maintaining network uptime in rugged industrial settings.

Problem Solved

Ensures stable and reliable network connectivity for automation equipment in factories with wide temperature fluctuations and airborne particulate matter, preventing system downtime.

2. Intelligent Transportation Systems (ITS) Network Backbone

With NEMA TS2 certification and a wide operating temperature, this switch is perfectly suited for ITS applications like traffic control cabinets or roadside communication units. The fiber optic ports allow for extended data transmission distances, while redundant power inputs and network redundancy protocols (Turbo Ring/Chain) ensure continuous operation despite power fluctuations or cable breaks.

Problem Solved

Provides robust and resilient network infrastructure for critical traffic monitoring and control systems, ensuring uninterrupted data flow and quick recovery from network failures.

3. Oil and Gas Field Data Acquisition

The switch's ability to operate in temperatures from -40 to 75°C, coupled with its robust metal housing and redundant power options (9.6-60 VDC input), makes it highly suitable for data acquisition and control in remote oil and gas fields. The fiber optic links can extend network reach across geographically dispersed sites, providing reliable communication for sensors and RTUs under challenging environmental conditions.

Problem Solved

Facilitates secure and stable data communication from distributed sensors and control devices in remote and exposed oil/gas environments, resisting temperature extremes and ensuring power continuity.
