Power consumption table
Principle
Principle
The 5 V  voltage required for the logic power supply to the I/O modules is supplied
by the following NIM network interface, BOS bus expansion and auxiliary power
supply modules from the 24 V  power supply.
These modules provide a max. current of 1200 mA at 5 V  (1):
 NIM network interface module placed at the beginning of the primary segment.
 BOS bus expansion module placed at the beginning of each expansion segment.
 CPS auxiliary power supply module placed within a segment.
The power consumption per segment must be calculated to ensure that the current
required by the I/O modules does not exceed the current supplied by the different
power supply modules.
If necessary, add an STBCPS2111K auxiliary power supply to the segment (s) where
this is the case.
The STBCPS2111K module must be used in conjunction with a power distribution
module STBPDT10K.

must.be.used.to.create.the.power.consumption.table
Use one calculation page per segment (1)(2).
For each segment:
 In the “Number” column indicate the required number of I/O modules for each
reference.
 In the “Total” column calculate the total current based on that number.
 In box 1, enter the grand total of all these values (mA) (1).
 The total in box 1 must be less than or equal to 1200 mA (1), box 2 or box 4
(if an expansion segment). If it is higher, add an auxiliary power supply, box 3.
The Advantys or Unity Pro conguration and debugging software creates the power
consumption table automatically depending on which temperature range is chosen
(standard, extended, etc.).
