The ITP 1622/1604 are  industrial grade, L2 Fast Ethernet  Power over Ethernet switches that provide 16x 10/100Base- TX IEEE 802.3at compliant PoE+ ports which are classified as power source equipment (PSE) and provides up to 30 watts of power per port with a maximum power budget of 120W. An additional 22/4x 10/100/1000Base-T(X) GbE ports are also provided. Housed in rugged wall mountable enclosures, these switches are designed for IEEE 802.3af/at compliant powered devices (PDs), such as surveillance cameras, wireless access points, and IP phones. The PoE switches use M12 connectors to ensure tight, robust connections and guarantee reliable connections against vibration and shock. These models are also compliant with EN50155, covering power input voltage, surge, EFT, ESD, vibration and shock, making these switches suitable for industrial applications, such as vehicle, rolling stock, or vessel. With a wide power input range of 24/48/72/96/110VDC (operating range 20 to 137.5VDC), this product series is especially suitable for rolling stock and track side installations.

Technical Notes

EN50155 Switches for Rail, Metro and Transport Applications

The ITP series of Ethernet switches are certified to EN50155. This internationally recognised standard particularly addresses the deployment of electronic equipment on rolling stock for railway applications. However the ITP range are equally well suited for use in any harsh environment. The ITP Ethernet switches are vibration and shock resistant and provide stable and reliable operation for mission-critical applications.
