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 5069 Compact 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
and establishes a new SA power bus for modules to the right.
The SA power bus that is established by a field potential distributor functions in
the same way as the SA power bus that a 5069-AEN2TR EtherNet/IP adapter
establishes, as described on
page 14.
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.
