Selected model

EMG8508

  • Atop’s EMG8508 IP67-rated Railway-compliant Ethernet switch is the best solution for providing high-speed Gigabit connectivity in bayside or carriage side Railway applications. Its rugged, aluminum enclosure can effectively protect the Switch core in any environment. The eight-M12 Gigabit ports can supply up to 30W of PoE Power (802.3af or 802.3at) to your PoE device, providing an overall maximum budget of 240W. This makes EMG8508 the ideal solution for on-board or off-board surveillance by simplifying the wiring where it’s difficult, risky and expensive to introduce new elements. The embedded redundant-power supply input provides a reliable and failure-proof safety mechanism to minimize down-times. EMG8508 comes in either redundant Low-Voltage DC power input (12-57 VDC, 47-57 VDC for PoE models) or in redundant High- Voltage DC power input (50-145 VDC). Each power module, including a Relay-output alarm, uses a S-coding M12 connector that makes EMG8508 ideal and simple for engineers setting up a Fault-Alarm System. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EMG8508 supports user account, password policy, and authentication interface management functions that comply with IEC62443 standard. Its IP67 housing protection, combined with a wide operating temperature of -40 to 70°C and wall mounting capacities, make it suitable to most Railway applications in harsh environments or industrial field applications.
  • Up to 8 10/100/1000 BASE-T(X) ports, M12 connector
  • Up to 4 or 8 802.3af or 802.3at compliant PoE ports
