Industrial Applications

1. Remote Oil & Gas Pipeline Monitoring Stations

Connecting various sensors (pressure, flow, temperature) and control devices in remote oil and gas pipeline monitoring stations to a central control room.

Problem Solved

The switch's wide operating temperature range (-40 to 75°C) and Class I Div. 2/ATEX Zone 2 certifications allow it to function reliably in extreme and potentially explosive environments often found in oil and gas fields. The redundant power inputs (9.6-60 VDC) ensure continuous operation even with power fluctuations from solar/battery systems, while the fiber optic port (100BaseFX ST) extends connectivity over long distances to a central hub, bypassing electrical interference.

2. Rail-Wayside Signaling and Communication Systems

Providing network connectivity for signaling equipment, trackside sensors, and communication systems along railway lines.

Problem Solved

The EN 50121-4 and NEMA TS2 certifications ensure the switch can withstand the severe shock, vibration, and temperature fluctuations inherent to railside deployments. Its robust aluminum IP30 housing protects against dust and debris, and the combination of copper (7x RJ45) for local device connections and fiber (1x ST) for longer runs between signaling cabinets or to control centers makes it ideal for distributed rail infrastructure.

3. Marine Vessel Automation and Navigation Networks

Establishing a robust and resilient communication backbone for automation systems, navigation equipment, and surveillance cameras on commercial marine vessels or offshore platforms.

Problem Solved

The maritime certifications (ABS, DNV, LR, NK) guarantee reliable performance in harsh marine environments, including resistance to vibration, shock, and salt mist. The wide operating temperature range (-40 to 75°C) accommodates varying climate conditions at sea. Redundant power inputs are crucial for uninterrupted operation of critical ship systems, and the mixed copper/fiber ports enable connecting a variety of onboard devices while utilizing fiber for noise-immune links across different sections of the vessel.
