5069-FPD Field Potential Distributor Creates Additional SA Power
Buses
The 5069-FPD Field Potential Distributor lets you change the field-side power
distribution source for Compact 5000 I/O modules to the right of the field
power distributor. The field potential distributor passes MOD power bus
signals through to the next module in the system.
You can use a 5069-FPD field potential distributor to add an SA power bus to a
5069 Compact I/O system. The field potential distributor blocks the current
that passes across the SA power bus to the left of the field potential distributor.
It then establishes a new SA power bus for modules to the right.
The SA power bus that a field potential distributor establishes functions in the
same way as the SA power bus that a 5069 Compact I/O EtherNet/IP adapter
establishes functions.
Examples of system configurations that use multiple SA power buses include:
• The modules in the system collectively draw more than 10 A of SA
power. That is, the maximum current that one SA power bus
can provide.
• The modules in the system must be isolated according to module types,
such as digital I/O and analog I/O modules.
• The modules in the system are isolated according to the type of field-
side device to which they are connected. For example, you can separate
modules that are connected to field-side devices that require DC voltage
for SA power from modules that are connected to field-side devices that
require AC voltage for SA power.
