5. Product Overview
The PDT-NSM-7024-MP-I is a Small Form Factor Industrial Managed Network Switch, supporting
16 x 10/100/1000 BASE-T RJ45 Ports, all compliant with IEEE 802.3at PoE+, and 8 x 10/100/1000
BASE-T RJ45 Ports.
This model is designed for a nominal +48VDC Power Supply but can operate on input voltages
from +48-57VDC. It is ideal for use in applications that require management of larger numbers of
access ports, where there also a requirement for Power over Ethernet, whilst not requiring fibre
connections. The unit has dual power input connections to allow for power supply redundancy;
whichever input has the higher voltage will take over as the power supply feed for the device.
The device is designed for use in harsh industrial environments, and incorporating a rugged
aluminium housing, it can be operated across a wide temperature range (-40°C to +80°C) making
it suitable for most applications and has 4kV Surge Protection.
A typical application setup can be seen in the following diagram:
