Moxa TN-4516A-12PoE-4GPoE-WV-T Managed Ethernet Switch with 16 ports including 12 Fast Copper POE ports M12 (100 Mbps) and 4 Gigabit POE Copper ports M12 (1000 Mbps), Extended Temp -40 to 75 C operating temperature, dual redundant power inputs 16.8 to 137.5 VDC (24-110 VDC). EN50155 certified ideal for railway applications. The ToughNet TN-4516A-12PoE-4GPoE series M12 managed Ethernet switches are designed for railway applications, including rolling stock and wayside installations. The switches use M12 and other circular connectors to ensure tight, robust connections, and guarantee reliable operation in industrial environments where vibration and shock are commonplace. The TN-4516A-12PoE-4GPoE series Ethernet switches provide 12 fast Ethernet M12 ports with or without IEEE 802.3at/af compliant PoE (Power-overEthernet) function, and the Gigabit models have 4 Gigabit Ethernet interface with PoE function and with optional bypass relay function. The PoE switches are classified as power source equipment (PSE); they provide up to 30 watts of power per port, and can be used to power IEEE 802.3at/af compliant powered devices (PDs), such as IP cameras, wireless access points, and IP phones.
