  NXA-PDU-1508-8 Power Distribution Unit (240V / 10A)

CONFIG DIP Switch

The NXA-PDU-1508-8 uses an 8-position DIP Switch (labelled “CONFIG”) to specify a unique device 
address for itself in a NetLinx Control System (FIG. 10). 

Setting the Device Address of the PDU

The NXA-PDU-1508-8 firmware implements 8 AxLink device IDs, starting from the device ID denoted by the 
DIP switch. The device IDs used by the NXA-PDU-1508-8 are as follows:



Dev 1

: (Power Outlet 1) + (AxLink-Bank 1 Power) + (Input Voltage) + (Temp)



Dev 2

: (Power Outlet 2) + (AxLink-Bank 2 Power)



Dev 3-8

: (Power Outlets 3-8)

To set the Device Address:

1.

If connected, disconnect the power supply.

2.

Set the CONFIG DIP switch according to the values shown below: 

The device number is set by the total value of DIP switch positions that are in the ON position. Note that the 
ON position is indicated on the DIP Switch. 

If you later change the device number, remove and reconnect the power connector to enter the new device 
number into memory.

Power Outlets 1-8

The eight 100-240VAC 50/60 Hz, IEC C-13, 10A AC Power Outlet Connectors provide AC power to 
connected devices (FIG. 11). 



The PDU measures current use of each individual power outlet, including the two AxLink power 
outputs, with an accuracy of 0.1A.



The PDU also reports the total current use of the entire unit.
