The ITP-600-4PH24 is an unmanaged, Fast Ethernet, PoE switch that provides  6 x 10/100Base-TX PoE+ ports. The  switch is designed for industrial applications in harsh environments with Ethernet ports that utilize M12 connectors to ensure water-tight, robust connections and guarantee reliable operation against vibration and shock. The ITP-600-4PH24 Ethernet switches are compliant with EN50155, covering operating temperature, power input voltage, surge, ESD, vibration, and shock, thus making these switches suitable for industrial applications in vehicle, rolling stock and factory automation.

  •     Compliant with EN50155, covering operating temperature, power input voltage, surge, ESD, vibration, and shock
  •     Use M12/M23 connector anti vibration and shock for vehicle, rolling stock, and railway applications
  •     24/48VDC (20~57VDC) redundant dual input power with built-in very high efficiency (97~98%) to boost PoE output voltage to 50VDC
  •     Regulated PoE output voltage (50VDC) to stabilize PoE device, and guarantee delivery PoE power distance to 100 m
  •     Wide operating temperature -40~75�C (ITP-600-4PHE24)
  •     CE, FCC, EN50155 and EN50121-4 for railway certified
  •     Industrial Grade EMS, EMI, EN61000-6-2, EN61000-6-4 certified
