Industrial Applications

1. Industrial HMI and Local PLC Network Aggregation

Aggregates localized Ethernet-based communication within automation enclosures. It links human-machine interfaces (HMIs), master PLCs, and network-enabled remote I/O blocks. Because industrial control cabinets are susceptible to airborne dust and particulates, the switch's fanless passive cooling design ensures long-term operational reliability by removing mechanical fan failure points.

Problem Solved

Prevents dust-induced cooling failures in enclosed cabinets while allowing 8 high-speed gigabit drops to seamlessly exchange real-time automation data.

2. Localized IP Surveillance and NVR Data Uplink

Acts as an unmanaged distribution switch for up to seven high-resolution IP surveillance cameras inside localized zones (e.g., manufacturing cells, isolated storage bays). Its 16 Gbps switching backplane capacity paired with 15 KB Jumbo Frame support allows for smooth, continuous high-definition video streaming to a local Network Video Recorder (NVR) without frame drops or network congestion.

Problem Solved

Eliminates camera packet loss and streaming jitter on local sub-networks by providing dedicated Gigabit backplane performance and massive frame handling.

3. Test Bench and Laboratory Instrument Interconnection

Interconnects modern benchtop laboratory instruments (digital oscilloscopes, spectrum analyzers, signal generators) to an engineering workstation or automated test host. Utilizing its zero-configuration plug-and-play capability, laboratory technicians can rapidly deploy, split, or modify local subnets for SCPI command automation and large waveform file retrievals without risking network IP conflicts or routing overhead.

Problem Solved

Removes complex network setup delays during laboratory testing, ensuring immediate gigabit-speed data access and robust control over multiple instruments.
