Overview / Buoyant platform

Onboard connectivity powered
directly by the train.

Buoyant-18PL2 is designed for high-speed Gigabit connectivity inside railway carriages. Fourteen or sixteen M12 ports can power onboard cameras and other edge devices from a shared 240 W budget.

Redundant 77–137.5 VDC inputs connect directly to train power, while the sealed enclosure, alarm relays and wide temperature range support reliable onboard operation.

Product highlights
  • Direct 110 VDC rolling-stock input
  • Fourteen or sixteen M12 PoE ports
  • Sealed housing for onboard rail
  • Hardware-based IEEE 1588v2 timing
