Technical Specifications Port Quantity:2×10/100Mbps auto‑negotiation RJ45 Ethernet ports Protocol Support:SRTP, Modbus‑TCP Backplane Power Consumption:240mA @5VDC Isolation Voltage:1500V RMS Operating Temperature:0℃～+60℃ Storage Temperature:-40℃～+85℃ Relative Humidity:5%‑95%, non‑condensing Certifications:CE, UL, cUL
Functional Features ER version firmware, dual 10/100Mbps Ethernet ports, auto‑negotiation, support mainstream industrial Ethernet protocols, communication fault diagnosis, front‑panel link‑activity LED status display.
Application Scenarios RX3i PLC Ethernet communication expansion, ER‑configured spare replacement, HMI and SCADA network connection.
Performance Parameters 10/100Mbps auto‑speed adaptation Communication fault detection capability Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel LED indicators for link, activity and fault status Dual RJ45 Ethernet sockets Backplane gold‑finger bus contact Internal Ethernet processing circuit with ER firmware Mechanical locking latch
Working Principle Module realizes high‑speed data exchange with RX3i CPU through backplane bus. ER firmware executes Ethernet protocol stack processing. Dual physical ports complete sending and receiving of network data packets. LED lamps reflect port link state and data transmission activity.
Installation Requirements Mount into free slot of RX3i main or expansion rack. Complete cabinet protective ground. Configure IP parameters via programming software. Use shielded twisted‑pair network cables. Power‑off rack before module replacement. Separate network wiring from high‑voltage power cables.
Usage Notes Avoid IP address conflict within local network. Diagnose network fault according to LED status. On‑site disassembly is forbidden. Keep away from corrosive gas and liquid splash.
