The Advantech EKI-2525LI is a slim unmanaged Fast Ethernet switch designed for space-constrained industrial applications. Featuring 5x 10/100 Mbps copper ports with auto-negotiation and Auto MDI/MDI-X support, it provides simple and reliable connectivity for control systems, monitoring devices, and edge network infrastructure.
To maximise system uptime, the EKI-2525LI offers redundant 12–48 VDC dual power inputs alongside an additional DC power jack, ensuring flexibility in installation and protection against unexpected power supply failures. A built-in relay output provides fault signalling for power failure events, giving engineers real-time notifications that reduce troubleshooting time and system downtime.
The switch’s compact IP40-rated metal enclosure is optimised for DIN-rail or wall mounting, making it an ideal choice where cabinet space is limited. Despite its slim form factor, it is engineered for harsh industrial environments, with robust protection against reverse polarity and overload current. It also supports a wide operating temperature range from -40°C to +75°C, guaranteeing reliable performance in extreme climates and demanding field conditions.
LED indicators provide clear visibility of power, link status, and port activity, enabling straightforward network monitoring and maintenance. With an MTBF of over 6.8 million hours, the EKI-2525LI delivers long-term durability and reliability, reducing total cost of ownership in industrial automation, utilities, energy, and transport applications.
