DG-SW3080 - 8 Port Managed Railway Ethernet switch

Overview

Dragontech’s Ethernet switches are designed for use in all industrial, in-vehicle, and railway applications. The DG-SW3080 is a EN50155 compliant managed Redundant Ring Ethernet switch with 8x10/100Base-T(X) ports. Full support for Ethernet Redundancy protocols such as O-Ring, Open-Ring, O-RSTP and MSTP/RSTP/STP (IEEE 802.1s/w/D) ensures your mission-critical applications are protected against network interruptions or temporary malfunctions with its fast recovery technology. This switch is specifically designed and qualified for the toughest environmental conditions. DG-SW3080 switch uses M12-series connectors to ensure tight and robust connections, and guaranteed reliable operation in all operating conditions encountered in railway applications. The DG-SW3080 can centrally managed using a windows utility. The wide operating temperature range from -40°C to 70°C and EMC compliance meets the requirements of rolling stock installations.
