Westermo releases three Ethernet devices that support the growing need for higher bandwidth networks with industrial applications. Two new Gigabit switches and a media convertor offer outstanding reliability, robustness and ease of installation, making them suitable for heavy industrial, maritime and rail trackside data communication networks.
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.
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. Using Westermo’s range of pluggable 100Mbit or Gbit SFP transceivers, different types of fibre can be easily converted and distances of up to 120km can be achieved.
The three devices are designed for demanding applications that require high levels of reliability. 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 and increases reliability. By using only industrial grade components the units are robust and provide a long service life. The SDW-541-F1G-T4G has a mean-time-between-failure of over 1.1 million hours.
To simplify installation 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 all meet the highest 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. A power input range of between 10 and 57 VDC and an extended operating temperature range of -40 to +74 C enable the units to support a broad range of applications, even in extreme environments.
