PoE
The PET-7H16M module has integrated Power-over-Ethernet (PoE), it allows power and data
to be carried over a single Ethernet cable, so a device can operate solely from the power it
receives through the data cable. This innovation allows greater flexibility in office design,
higher efficiency in systems design, and faster turnaround time in set-up and
implementation. The PET-7H16M module feature true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) using both Ethernet pairs (Category 5 Ethernet cable).
The PET-7H16M module can receive power from an auxiliary power sources like AC adapters
and battery in addition to the PoE enabled network. This is a desirable feature when the
total system power requirements exceed the PSE's(power sourcing equipment) load capacity.
Furthermore, with the auxiliary power option, the PET-7H16M module can be used in a
standard Ethernet (non-PoE) system.
When using PoE devices like PET-7H16M, you can choose ICP DAS "PoE"
switch —"NS-205PSE" as the power source, NS-205PSE automatically detects the connected
devices whether they are PoE devices or not. This mechanism ensures NS-205PSE to work
with both PoE and non-PoE devices coordinately at the same time.
Being as a power source for PoE devices, NS-205PSE requires its power input ranging from
+46 ~ +55VDC.
