Chapter 2 Compact 5000 I/O Serial Module Operation in a Logix 5000 Control System
5069-FPD Field Potential Distributor
The controller or adapter, based on whether the module is a local or
remote I/O module, is the primary source of field-side power, that is, SA
power, in the system. However, you can use a 5069-FPD field potential
distributor to break field-side power distribution in a system and establish a
new SA power bus.
Field-side power passes across the internal circuitry of the Compact 5000 I/O
modules beginning with the controller or the adapter. The field potential
distributor blocks the passage of field-side power from the left and functions as
a new field-side power source for the modules to the right.
