Two PoE switches, the 5-port 24 Vdc powered EKI-2525PA and 6-port wide temperature EKI-2526PI, combine a compact and rugged unmanaged Ethernet switch with Power-over-Ethernet (PoE) technology to connect and power Ethernet devices over a single Ethernet cable.
With the EKI-2525PA, there is no need for a separate 48 Vdc power source, since it includes a dc-to-dc converter to boost the 24 Vdc input to the 48 Vdc required for powering attached PoE devices.
For compatibility with non-PoE compliant devices, each port can automatically detect when PoE compliant devices are attached, before supplying power. Each Ethernet port is also equipped with front-facing LED indicators that provide link, transmission speed, activity and PoE output status to aid in diagnosing issues with cables and attached devices.
Packaged in a compact and thin DIN-rail mount metal chassis, both modules fit in small spaces. They are rugged with redundant power inputs, 4,000 Vdc Ethernet ESD protection, power line surge (EFT) protection of 3,000 Vdc, and feature an operating temperature range of -10 to 60‚° C or -40 to 75‚° C to ensure system uptime. Plus, these switches are CUL (UL/CSA), CE, FCC, and RoHS/WEE certified.
