SIEMENS

Main Functions

Industrial Ethernet switching & media conversion: Realize data switching between electrical ITP copper interfaces and multimode fiber‑optic interfaces. Extend communication distance and isolate electrical interference via optical fiber transmission for 10/100 Mbit/s Industrial Ethernet networks.
Integrated media redundancy manager: Support optical ring network redundancy. When fiber cable breaks, the module performs fast network rerouting to keep the whole Ethernet ring available, avoiding total network outage.

Redundant power supply design: Dual independent 24 VDC power‑input terminals. The module continues working if one power circuit fails, improving power‑supply reliability for critical automation networks.
Multi‑channel digital diagnostic inputs: 8 built‑in digital input channels collect external field‑contact status signals. Link alarm information to internal network diagnosis and relay alarm‑contact output.
Network management capability: Support SNMP and web‑based management. Users can read port status, network fault statistics and module running parameters remotely via upper‑level network management software.
Hardware alarm relay contact: Provide hardware signal‑relay contact for fault alarm. It can connect to PLC or DCS to report module failure, port fault or ring‑network breakdown.
Industrial anti‑interference hardware: DIN‑rail mounting metal housing, designed for control‑cabinet installation. Resist EMC interference in heavy‑industry workshop environments.
Port status LED indicators: Visible LED lamps show power status, link activity, ring‑network health and fault conditions for fast on‑site troubleshooting.

Applicable communication system: Siemens Industrial Ethernet / PROFINET automation networks.
Connected field devices: PLC, HMI, distributed I/O systems, variable‑frequency drives and other automation nodes with Industrial‑Ethernet interfaces.
Target industries: Thermal power plants, petrochemical plants, metallurgy, paper‑making, automobile manufacturing and other heavy‑process‑industry sites.
Purpose: Build long‑distance, anti‑interference and redundant optical‑ring Industrial‑Ethernet backbones. Solve ground‑loop interference and long‑distance transmission problems in harsh industrial environments. Deliver stable network communication for critical‑control automation systems. It serves as important spare‑part for legacy SIMATIC NET network installations.
