Buoyant 12PL3 Series 50155 Certified

The Buoyant IP67-rated Railway-compliant Ethernet switch is the best solution for providing high-speed Gigabit connectivity in bay side or carriage side Railway applications along with high performance L3
functions. Its rugged, aluminium enclosure can effectively protect the Switch core in any environment. The 8 PoE ports out of 12-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. This makes this switch 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.


Upto 4 Gigabit SFP slots provide this switch Series the capability to be connected with Fiber-Optics to the backbone without the need of Copper Ethernet repeaters and without any risk of signal degradation. The embedded redundant-power supply input provides a reliable and failure-proof safety mechanism to minimize down-times.


The switch 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 it ideal and simple for engineers setting up a Fault-Alarm System. Its IP67 housing protection, combined with a wide operating temperature of -40 to 75°C and wall mounting capacities make it suitable to most Railway applications in harsh environments or industrial field applications.
