PRS-NSP Network 

Splitter

25.1 Introduction

The PRS-NSP Network Splitter is used to create 
short-circuit proof tap-off points in the network. A 
network may contain up to 10 network splitters.

This unit in metal housing is the successor of the 
LBB4410/00 in plastic housing.
 

25.2 Controls 

and 

connectors

The exterior of the network splitter (see figure 25.2) 
contains the following:
1 External power supply - A connection for an 

(optional) external power supply. The external power 
supply only feeds the tap-offs (see section 25.3.3).

2 Tap-off 1 - A system bus connector for creating a 

tap-off. The tap-off is protected against short-circuits 
and has a maximum load of 2.5 A (see 
sections 25.2.2 and 25.3.2).

3 System bus - A system bus connector for looping 

through the main branch (see section 25.3.2).

4 Lid - A lid that provides access to the jumpers (see 

section 25.2.2). The rear side of the lid contains a 
label with explanation about the internal settings.

5 Fault LED - A yellow fault LED that provides 

information about the status of the network splitter 
(see section 25.5).

6 Power LED - A green power LED that provides 

information about the status of the network splitter 
(see section 25.5).

7 Tap-off 2 - A system bus connector for creating a 

tap-off. The tap-off is protected against short-circuits 
and has a maximum load of 2.5 A (see 
sections 25.2.2 and 25.3.2).

8 System bus - A system bus connector for looping 

through the main branch (see section 25.3.2).

Note
It is not allowed to connect more than two other 

network splitters to a tap-off of a network splitter 

that is located in the main loop of the network.
