Overview

The WESTERMO SDW-550 EC is a rugged, unmanaged industrial Ethernet switch designed for reliable network connectivity in harsh environments. It provides plug-and-play operation without configuration, making it ideal for decentralized automation and transport networks. Its robust design includes dual power inputs, galvanic isolation, and compliance with industrial and automotive standards, ensuring protection against electrical transients, ground loops, and vibration.

Technical Data

Key Features

• Redundant Power Inputs: Maintains operation if one power source fails, improving uptime.

• Galvanic Isolation: Prevents ground loops and protects connected devices from electrical surges.

• Harsh Environment Tolerance: Suitable for extreme temperatures, vibration, and unheated enclosures.

• Diagnostics Support: DIP switches for port speed/duplex locking and port mirroring for troubleshooting.

• Protocol Transparency: Works with EtherNet/IP, PROFINET, Modbus TCP, and other industrial Ethernet protocols.

Typical Applications

• Transportation Systems: Onboard buses, rail vehicles, and trackside equipment, leveraging E-Mark certification for EMC compliance.

• Factory Automation: Connects PLCs, HMIs, and sensors in production lines and machinery under harsh conditions.

• Oil & Gas / Mining: Provides reliable connectivity in remote and extreme environments.

FAQ

Q1: Why is the SDW-550 EC unmanaged?
A1: Unmanaged switches are plug-and-play with no setup required, ideal for simple networks and fast field replacement.

Q2: What does the "E-Mark" certification indicate?
A2: Compliance with EMC standards for vehicle installations (ECE R10/10R-04), suitable for buses, trucks, and utility vehicles.

Q3: Can this switch be used in Gigabit networks?
A3: No, the SDW-550 EC supports only 10/100 Mbps. For Gigabit Ethernet, a model like SDW-550-T5G is required.
