Praesideo PRS-NSP
Network Splitter |
|
|
Features: |
|
Two current-limited network tap-offs
Supports redundant network connection on main
loop
Can feed power from an external supply to the
network
Indicators for power and fault status
The network splitter is used in a network to
provide two branches from the main cable run.
It can use an external DC power supply, or it
can use the power supply from the network controller.
The unit automatically switches to the local power
supply unit when it is connected to it, reducing
the power drain on the main network. For more

|
|
Features: |
|
- Redundant network connection
- Indicators for power and fault status
- Two supervised control inputs (not PRS-FINNA)
- Can use a local power supply
Most of the Praesideo system units have plastic fiber
optic interfaces. Plastic fiber is used to interconnect
nodes which are less than 50 meters apart. For distances
of more than 50 meters, glass fiber optic cable is used.
A fiber interface converts from plastic to glass fiber,
and vice versa. For more information download the Datasheet
