Advantech Introduces EKI-9520G, 20-Port EN 50155 Ethernet Switch for Railway Rolling Stock

As rail operators worldwide accelerate investment in digital passenger services—from on-board Wi-Fi and infotainment to real-time passenger information systems—the demand for certified, high-density networking infrastructure for rolling stock has never been greater. Advantech, a global leader in Edge Computing and IoT automation solutions, today announced the EKI-9520G Series—EN 50155-certified, 20-port Ethernet switches purpose-built for railway comfort network deployments. Available in L2 and L3 models with IEC 61076-2-010 compliant push-pull M12 connectors, IP67-rated rugged housings, and built-in real-time thermal monitoring with dashboard visibility, the series delivers reliable, manageable on-board passenger network infrastructure for railway rolling stock. The EKI-9520G Series joins Advantech's EN 50155-certified M12 Ethernet switch portfolio spanning 8 to 28 ports, giving rolling stock engineers a scalable networking solution for diverse on-board requirements.

Engineered for Railway Comfort and Operational Networks

The EKI-9520G Series meets EN 50155 railway certification requirements—including fire protection, shock, vibration, and EMC standards for rolling stock—and is available in L2 models, with L3 models scheduled for release in December 2026. Compliant with IEC 61375-3-4 Ethernet Consist Network standards, the series ensures interoperability across on-board devices from multiple vendors. The EKI-9520G Series also incorporates cybersecurity features referencing IEC 62443-4-2 requirements, addressing the growing security demands of modern railway networks. Together, the L2 and L3 models provide a scalable networking solution for comfort and operational systems across rolling stock applications.

Rugged M12 Connectors with IP67 Protection

The EKI-9520G Series features IEC 61076-2-010-compliant push-pull M12 connectors enabling tool-free installation and secure locking connection in high-vibration environments. All ports are protected to IP67 against dust and water ingress for reliable operation onboard railway rolling stock.

Real-Time Thermal Monitoring for Network Reliability

The EKI-9520G Series integrates a thermal sensor for real-time temperature monitoring, with data accessible directly through the management dashboard to help prevent downtime by identifying thermal issues before they occur. With an operating temperature range of -40°C to 70°C, the switch is designed to withstand the thermal extremes encountered in rolling stock installations worldwide.

Flexible PoE Power Delivery for Passenger Service Devices

PoE-equipped models support IEEE 802.3af/at on up to 16 ports, with a PoE power budget of up to 120W, simplifying deployment of passenger service devices such as Wi-Fi access points, IP cameras, and passenger information displays without the need for separate power cabling. With a wide 24 to 110 VDC power input range (operating from 16.8 to 137.5 VDC), the EKI-9520G can be installed across rail vehicle regardless of the on-board power standard.
