The Advantech EKI-2525SI-AE is a rugged unmanaged Ethernet switch equipped with four 10/100 Mbps RJ45 copper ports and one 100FX single-mode SC fiber port. It enables long-distance Ethernet communication up to 30 km, providing a highly reliable solution for industrial networks that need stable, interference-free backbone links.
Designed for deployment in demanding environments, the switch is housed in a compact IP30-rated metal enclosure and supports flexible DIN-rail or wall mounting. Its extended wide operating temperature range from -40°C to +75°C ensures stable performance in harsh outdoor or unconditioned locations such as roadside cabinets, substations, or production facilities.
Redundant 12–48 VDC power inputs enhance system resilience, while built-in protections such as reverse polarity and overload current tolerance safeguard against electrical faults. The integrated relay output provides fault alarms to immediately notify operators of power or connection issues, minimising downtime.
Other features include broadcast storm protection, auto MDI/MDI-X for simplified cabling, and support for store-and-forward switching to ensure reliable packet delivery. With a long MTBF rating and industrial EMC certifications, the EKI-2525SI-AE is a cost-effective choice for extending Ethernet networks over long distances in energy, utilities, transport, and automation applications.
