31004624 8/2009
Logic Power Flow
The figure below shows how the NIM’s integrated power supply generates logic
power and sends it across the primary segment:
The figure below shows how the 24 VDC signal is distributed to an extension
segment across the island:
The logic power signal is terminated in the STB XBE 1100 module at the end of the
segment (EOS).
Island Bus Loads
The built-in power supply provides logic bus current to the island. If the logic bus
current drawn by the I/O modules exceeds the available current, install additional
STB power supplies to support the load. Consult the Advantys STB System
Planning and Installation Guide for the current provided and consumed by
Advantys STB modules at various operating temperatures and voltages.
