研华EN50155工业交换机简介：
EKI-9512DP M12 Managed Ethernet Switch is designed for railway applications, including rolling stock. EKI-9512DP switch uses M12 connectors to ensure tight, robust connections, and to guarantee reliable operation against environmental disturbances, such as vibration and shock. EKI-9512DP provides 12 Fast Ethernet M12 ports with 8 IEEE 802.3at/af compliant PoE /PoE ports. The PoE /PoE switch is classified as power source equipment (PSE) and provides up to 30/15.4 watts of power per port, and can be used for IEEE 802.3at/af compliant powered devices (PDs), such as IP cameras, wireless access points, and IP phones. In addition, EKI-9512DP provides a wide power input range of 24/36/48 VDC, 72/96/110 VDC; the dual, redundant power input increases the reliability of your communications system. The -40 to 70°C operating temperature and IP67-rated waterproof enclosure allow deployment in harsh environments. EKI-9512DP is compliant with the essential sections of the European railway standard EN 50155, EN50121-3-2 covering operating temperature, power input voltage, surge, ESD, and vibration, making the switches suitable for a variety of industrial applications.
