1.Core Functions

Plug-and-Play Layer 2 Data Switching (Core Basic Function) Unmanaged design requires no configuration after power-on. Automatically identifies 10/100 Mbps devices with auto full/half duplex negotiation, self-learns MAC addresses to isolate collision domains, and forwards high-speed Ethernet data between PLCs, variable frequency drives and HMIs.
8-Port 100M Industrial Ethernet Port Expansion 8 RJ45 copper ports support simultaneous connection of multiple automation devices, solving insufficient built-in Ethernet ports inside control cabinets and building star topology local equipment networks.
Wide Operating Temperature & Harsh Industrial Environment Resistance Conformal coated printed circuit board resists dust, humidity, vibration and heavy electromagnetic interference for factory, power plant and metallurgy sites; reliable cold startup from -40℃ up to 75℃ continuous operation.
Wide-Range DC Power Supply Compatibility 9.6 ~ 32 VDC wide voltage input, directly powered by standard 24 VDC cabinet control power supply. Communication links remain stable under grid voltage fluctuation and transient voltage drop.

Auto MDI / MDI-X Port Polarity Auto-Correction Each port automatically detects straight-through or crossover Ethernet cables, eliminating cable type differentiation and simplifying on-site wiring to reduce construction errors.
Link Status LED Indicators for Quick Maintenance Dedicated Link/Act LED for every RJ45 port to visually display link connectivity and data transmission status, enabling rapid troubleshooting of broken cables or offline equipment.
Fanless Passive Cooling for Long Service Life Fan-free passive heat dissipation design removes risks of fan wear and dust accumulation, supporting 24/7 continuous operation with minimal maintenance requirements.
Standard DIN Rail Modular Mounting Compatible with standard 35 mm DIN rails inside electrical cabinets, supports horizontal & vertical snap-on installation to save cabinet space and simplify OEM cabinet layout design.

Schneider PLC Automation Control Cabinets (Primary Application) Matched with Modicon M251/M340/M580 & EcoStruxure PLCs to expand 8-channel Ethernet interfaces for variable frequency drives, servo drives and touchscreen HMIs, building factory Profinet / Modbus TCP industrial LANs.
Power Plant DCS & Gas Turbine Control Systems Installed in thermal & combined-cycle power plant DCS cabinets (Mark VIe, EcoStruxure DCS) to connect I/O modules, local HMIs and remote monitoring terminals for stable control signal transmission.
Water Treatment & Wastewater Plant Automation Systems Network water pumps, valves, water quality transmitters and PLCs inside outdoor control cabinets, with humidity resistance for damp sewage treatment environments.

Heavy Industry Metallurgy & Mining Sites Control cabinets for belt conveyors, ball mills and smelting production lines. Strong anti-EMI performance guarantees uninterrupted interlock communication during heavy motor startup/shutdown.
HVAC & Building Intelligent Climate Control Systems Central air conditioning, chiller unit control cabinets for shopping malls and data centers, networking temperature PLCs and remote monitoring terminals.
New Energy PV & Wind Power Booster Stations Communication expansion for wind turbine main controllers and box transformer protection devices. Wide temperature tolerance adapts to extreme day-night temperature difference for outdoor power stations, transmitting generation data to dispatching systems stably.
Port & Logistics Automated Conveying Lines Network sorting equipment, warehouse AGVs and conveyor PLCs for simultaneous multi-device Ethernet data exchange at container terminals and automated warehouses.

OEM Complete Electrical Control Equipment Matching Standard accessory for packaging machinery, plastic extruders, air compressors and machine tool control cabinets, providing low-cost multi-port expansion for equipment interconnection.
