Differentiation

Unmatched Network Scale: 65,534-node cascading – 100x larger than typical solutions (≤1,000 nodes), enabling plant-wide control.

Configuration-Free Integration: Auto-join EtherCAT networks – 70% faster deployment vs. traditional setups.

Modular Flexibility: 32 I/O modules per coupler adapt to sensors, actuators, and meters – one device fits all.

Industrial-Grade Circuit Protection: Triple safeguards (overvoltage/overcurrent/reverse polarity) reduce downtime by 90% in unstable grids.

Typical Applications

🏭 Automotive Production Networks: Cascade hundreds of couplers to synchronize welding robots and torque tools via EtherCAT.

📦 Smart Warehouse Systems: Monitor shelf inventory with DI modules across 10,000㎡ facilities – 100ms response to sorting commands.

Solar Farm Monitoring: Connect inverters and meters via cascaded couplers; RTD modules detect overheating risks.

🔧 Flexible Manufacturing Cells: Deploy 32 high-speed counters per coupler to track production cycles; trigger emergency stops via DO modules.
