The Advantech EKI-2525NI is a rugged, unmanaged 5-port Fast Ethernet switch designed to deliver reliable networking in compact industrial environments. With five 10/100 Mbps RJ45 ports, it supports auto-negotiation and Auto MDI/MDI-X, simplifying deployment and ensuring flexible connections with a wide variety of devices.
Built for PROFINET-based automation systems, the switch integrates a PROFINET PTCP filter to prioritise traffic for time-critical control protocols. This makes it particularly effective in factory automation, process control, and machine-to-machine communication where deterministic networking is vital.
The EKI-2525NI supports a single 12–48 VDC power input with lockable 3-pin terminal block, providing stable operation with built-in reverse polarity and overload protection. Power efficiency is further enhanced with its low consumption design, while a robust IP30-rated metal enclosure ensures durability in dusty or harsh industrial conditions.
Its slim, compact design makes it easy to mount on DIN-rails, even in space-constrained cabinets. The switch also supports a wide operating temperature range of -40°C to +75°C, ensuring dependable performance in extreme environments such as outdoor enclosures, energy substations, and transportation systems.
With CE/FCC Class A compliance, EN 61000-4 industrial EMC protection, and an MTBF rating designed for long lifecycle use, the EKI-2525NI offers a reliable and cost-effective networking solution for industrial automation.
