GE IS220PPDAH1B Power Distribution System Feedback I/O Pack

GE IS220PPDAH1B Power Distribution System Feedback I/O Pack

Functional Description

The Power Distribution System Feedback (PPDA) I/O pack produces system feedback signals for power bus

voltages, branch circuit status, ground fault detection, and bulk power supply health from the connected

core distribution board(s). The I/O pack accepts inputs from up to a maximum of six power distribution

boards or up to six sets of feedback signals. It conditions the board feedback signals and provides a dual

redundant Ethernet interface to the Mark VIe or Mark VIeS controllers. The PPDA feedback is structured to

be plug and play, using electronic IDs to determine the power distribution boards wired into it. This

information is then used to populate the IONet output providing correct feedback from connected boards.

Compatibility

At the heart of the core PDM is the PPDA I/O pack. This I/O pack is designed to accept inputs from up to six

different power distribution boards, condition the signals, and provide a dual redundant Ethernet interface

to the controllers. The feedback is structured to be plug and play meaning the PPDA is able to check the

power distribution boards that are wired into it using electronic IDs. It uses this information along with

ToolboxST configuration to populate the IONet signal space output with the correct feedback signals from

connected boards.

The PPDA I/O pack is hosted by the JPDS, JPDM, JPDG, or JPDC 28 V dc control power boards on the Mark*

VIe control Power Distribution Module (PDM). It is compatible with the feedback signals created by JPDB,

JPDE, and JPDF.
