Power Consumption
The c 5 V logic power supply for the I/O modules is provided by the following
modules:
b NIM network interface module placed at the beginning of the primary segment.
b BOS bus extension module placed at the beginning of each extension segment.
b CPS auxiliary power supply placed within a segment.
The NIM, BOS and CPS modules use their c 24 V power supply to deliver a
maximum current of 1200 mA at a voltage of c 5 V.
The power consumption per segment must be calculated to ensure that the current
demanded by the I/O modules does not exceed the current supplied by the different
power supply modules.
If necessary, add an auxiliary power supply STB CPS 2111 in the segment(s)
concerned.
For each segment:
b In the “Number” column indicate the required number of I/O modules for each
reference.
b In the “Total” column calculate the total current based on that number.
b In box
b The grand total in box
greater, add an auxiliary power supply module, box 3.
The Advantys STB SPU 1ppp configuration and debugging software calculates the
power consumption automatically. You can also use an Excel spreadsheet available
from your Regional Sales Office or from wwwtelemecanique.com.
