8-Port EN50155 Certified Railway IP67 waterproof Managed Layer 3 Gigabit PoE Switch


ATOP’s EMG8608 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 8-M12 Connectors 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.

The embedded redundant-power supply input provides a reliable and failure-proof safety mechanism to minimize down-times. EMG8608 comes in redundant Low-Voltage DC power input (12~57 VDC, 47~57 VDC for PoE models). Each power module, includes a Relay-output alarm.

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 filed applications.
