Gigabit switches and media converter for industrial applications

Westermo's SDW-541-F1G-T4G and SDW-550-T5G Gigabit switches and the MCW-211-F1G-T1G media converter are suitable for heavy industrial, maritime and rail trackside data communication networks.

Westermo has launched three Ethernet devices that support the growing need for higher bandwidth networks with industrial applications. Two Gigabit switches—the SDW-541-F1G-T4G and SDW-550-T5G—and a media converter—the MCW-211-F1G-T1G—are suitable for heavy industrial, maritime and rail trackside data communication networks.

The MCW-211-F1G-T1G is an unmanaged industrial Ethernet media convertor with one SFP fibre port and one copper port that enables the connection of legacy serial devices to new Gigabit Ethernet networks. The SDW-541-F1G-T4G and SDW-550-T5G are unmanaged Ethernet switches that offer a choice of five copper or one fibre and four copper ports. The units support 100 Mbit/s or Gbit Ethernet, with the SDW-550-T5G also supporting 10 Mbit/s communications.

All three units feature tri-galvanic isolation, a unique solution that provides isolation between the ports, the shield connection and the power supply. This helps to avoid ground loop currents. The devices are compatible with all standard industrial Ethernet protocols. For legacy Ethernet equipment unable to support auto-negotiation, a DIP switch can lock data rate and flow control. Network diagnostics is simplified using the port mirroring functionality of the switches. This allows data flow through the switch to be monitored using a network analyser, enabling engineers to use it for fault diagnosis.

The units meet EMC, isolation, vibration and shock standards, and are certified for rail trackside and maritime applications. Their IP21 rating ensures that the units can be installed in locations where condensed water may occur. They also feature a power input range from 10 and 57 Vdc and an extended operating temperature range of -40 to +74 C, which enable the units to support a broad range of applications, even in extreme environments.
