8 POINT I/O 24V dc Expansion Power Supply
Publication 1734-IN058B-EN-P - June 2005
About the Power Supply
The expansion power supply passes 24V dc field power to the I/O
modules to the right of it. The expansion power supply extends the
backplane bus power for up to 17 I/O modules to the right of the
supply and creates a new field voltage partition segment for driving
field devices. The expansion power supply separates field power
from I/O modules to the left of the unit, effectively providing
functional and logical partitioning for the following.
• Separate field power between input and output modules.
• Separate field power to the analog and digital modules.
• Group modules to perform a specific task or function.
The dark-gray color of the expansion power supply allows for easy
visual inspection and identification. Refer to the figure to identify
external power supply components.
Use multiple expansion power supplies with POINT I/O adapters to
assemble a full system. With any POINT I/O adapter, use an
expansion power supply to add additional modules in 4-17 module
increments, for a total of 63 I/O modules.
