The Advantech EKI-2525I-BE is an Ethernet module 5-port 10/100Mbps unmanaged FE switch (WideTemp.) designed for mission critical applications ranging from in-vehicle applications to industrial automation. This device has an extended temperature of -40 to 85degC for full feature operation under harsh environments. It also has a wide input voltage range from 9V to 48V DC to power under any conditions. For31different fiber applications, the EKI-2525I-BE offers 10/100Mbps fiber ports for single and multimode fiber cable options, and is backward compatible with former 10Mbps version fiber products. Each fiber port is capable of supplying an uplink to up to 2km and work well long distances from the switch itself. Furthermore, the EKI-2525I-BE supports wirespeed performance, full/half-duplex modes, per port auto-negotiation capabilities, and MDI/MDIX settings. Additionally, this device features advanced diagnostics LED indicators, allowing for easier troubleshooting and maintenance. The EKI-2525I-BE is an ideal option for mission critical applications with high reliability and performance needs.
