• Support DHCP client function for automatic IP address acquisition
• Optional C‑PLUG memory card for fast configuration backup and device replacement without re‑programming
• LED indicator lights display port status, power status and fault status

Application Scenarios

• Factory automation production lines, PROFINET IO distributed control networks
• Compact cabinet‑mounted industrial communication nodes for machine tools, packaging equipment
• Small‑size redundant ring network construction for process auxiliary control systems
• Industrial field‑level communication for logistics handling equipment

Performance Parameters

• Switching capacity: 1Gbps
• Latency: Low microsecond‑level real‑time forwarding for industrial real‑time traffic
• MTBF: High mean time between failures for continuous industrial operation

Material Composition

• Housing: Reinforced polycarbonate plastic with metal mounting hardware
• Internal circuit: Industrial‑grade FR‑4 printed circuit board, industrial communication chips

Structural Characteristics

• Flat slim housing design, 35 mm DIN‑rail mounting structure
• Terminal block for redundant power supply and fault signal output
• RJ45 ports arranged on front panel, LED status indicators visible on front face
• C‑PLUG slot for configuration storage

Working Principle

• Performs layer‑2 Ethernet frame forwarding, supports managed VLAN configuration, port isolation and QoS traffic scheduling
• MRP/HSR/PRP redundancy logic monitors network link status, triggers automatic link switch‑over upon link failure to eliminate communication interruption
• PROFINET IO stack realizes cyclic real‑time data exchange with PLC controllers

Installation Requirements

• Mount on standard 35 mm DIN‑rail inside industrial control cabinet, vertical installation orientation
• Maintain sufficient surrounding ventilation clearance, avoid heat‑source direct radiation
• Use shielded industrial Ethernet cables for RJ45 connections
• Two independent 24 V DC power sources for redundant power input to achieve power‑supply fault tolerance
• Ground the housing to cabinet protective earth according to EMC requirements
