User Manual Supplement 

Revision B 

 

 

2.4  Power requirements 

 
The SKF Multilog IMx-Rail is designed to be po

wered from the train’s

 DC supply. 

Nominal supply voltages between 24 and 110 V DC are accommodated by 
appropriate choice of IMx-Rail model (nominal 24 V DC or 110 V DC input). The 
supply to the IMx-Rail device should be protected by an appropriately rated fuse, 
refer 

3.3.2.

 

 
The incoming DC train supply, is connected via the 4-pole power connector mounted 
on the side of the IMx-Rail enclosure

Figure 1

. The pin designations and details for 

this connection are as shown i

Table 1

 below, two pins are available for each 

functional connection:

Description 

1 and/or 4 

Supply 0V (Internally connected to -Vin, power module terminal 2) 

2 and/or 3 

 (Internally connected to +Vin, power module terminal 1) 

 

A mating M12, A-coded, IEC 61076-2-101 cable mounting connector is supplied with 
the IMx-Rail and further quantities can be ordered under the following reference: 

 

CMON 4143:  Socket power supply connector for SKF Multilog IMx-Rail 

This has push-in connections and accommodates an external cable diameter of 4 to 
8 mm. Conductor cross sections (without ferrule) can be in the range 0.14 mm² to 
0.75 mm² (26 to 18 AWG). On assembly, after fitting into the rear part of the 
connector, the exposed individual conductor length should be 24 mm with 8 mm 
stripped back for insertion.  

Internally the incoming supply via this connector is pre-wired to the power module 
and the output of that power module is pre-wired to the IMx-16Plus module. 

On the top face of the power module there is a single 

(green) ’output on’ LED

 but no 

user controls or adjustments.  

Refer also to the important safety warnings on the following page. 

Note that (except in circumstances where the three relay outputs and LTE/GSM 
functions are all enabled), the IMx-16Plus also supports PoE (Power over Ethernet). 
This can be used as either a single or as a redundant power source, refer also to the 
SKF Multilog IMx-16/IMx-16Plus User Manual.
