6.8  Electrical Interfaces 

This section shows the schematics of the user accessible interface circuits, which are the +24V power input and 
copper Ethernet interfaces. 

6.8.1  +24V Power Input 

The power input interface schematic in the figure below shows the input protection diodes, common mode EMC 
filter and DC-DC converter. 

Power input must be 20VDC to +28VDC. Ideal input voltage is +24VDC 

and provided by a supply with a Safety Extra Low Voltage (SELV) rating. 

See section 2.0 for specification 

details.

6.8.2  Ethernet Interface 

The  Ethernet  interface  schematic  shown  in  the  figure  below,  is  identical  for  all  Ethernet  copper  ports.  This 
schematic shows the transformer isolation, REF (shield), and termination used.
