H Series Fieldbus 24VDC Expansion Power
Supply, Series A
(PSSSE24A)
The 24VDC expansion power supply unit (PSSSE24A) passes 24VDC
field power to the I/O modules to the right of the power supply. This
unit 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.
The expansion power supply also separates field power from I/O
modules to the left of the unit, effectively providing functional and
logical partitioning for:

You can use multiple expansion power units with the I/O adapters
to assemble a full system. For instance, if you are using the
PSSCDM12A or PSSCDM18PA adapter, you may use a PSSSE24A
expansion power unit to add additional modules in 5 to 17 module
increments. For example, if you had a 36 module system with a I/O
adapter, you would have two PSSSE24A expansion power units
to provide more PointBus current for modules to the right of the
supply.
