FUNCTIONAL DESCRIPTION FOR IS220PPDAH1B:

The IS220PPDAH1B is a Power Distribution System Feedback I/O Module designed and manufactured by General Electric as part of the Distributed Mark VIe control systems. The Power Distribution System Feedback (PPDAH1B) 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 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.

The PPDAH1B I/O pack is hosted by the JPDS, JPDM, JPDG, or JPDC 28 V dc control power distribution board on the Mark* VIe Control Power Distribution Module (PDM). Additional boards are connected using 50-pin ribbon cable jumpers that are wired pin 1 to pin 1. Each board contributes one feedback group to the PPDAH1B.

INSTALLATION:

• Directly plug the PPDA I/O pack into the JA1 terminal board connectors. The PPDA I/O pack mounts on a JPDG, JPDS, JPDM, or JPDC 28 V DC control power distribution board.

• Mechanically secure the I/O pack using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type.

• The bracket location should be adjusted such that there is no right-angle force applied to the DC-62 pin connector between the I/O pack and the terminal board. The adjustment should only be required once in the service life of the product.

• Plug in one or two Ethernet cables depending on the system configuration. The I/O pack will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.

• Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.

• Connect ribbon cables from connector P2 on JPDG, JPDS, JPDM, or JPDC to daisy chain other core boards feeding information to PPDA.

SIGNAL ROUTING:

The PPDA I/O pack is mounted to either a JPDG, JPDS, JPDM, or a JPDC board. Additional boards are connected using 50-pin ribbon cable jumpers that are wired pin 1 to pin 1. Each board contributes one feedback group to PPDA. This connection passes through up to five previous boards. The feedback groups are displayed as bold lines, and connectors P1 and P2 of each board are displayed. From right to left, the JPDS board hosts the PPDA I/O pack, and hookups are as follows:

• Local feedback from JPDS is on signal group A
• Feedback from JPDF is on signal group B
• Feedback from JPDB is on signal group C
• An additional JPDF would use signal group D
• An additional board would use signal group E

DIAGNOSTICS:

• A power-up self-test including checks of RAM, flash memory, Ethernet ports, and most of the processor board hardware.

• Continuous monitoring of the internal power supplies for correct operation.

• A check of the electronic ID information from the terminal board, acquisition card, and processor card confirming the hardware set matches, followed by a check confirming the application code loaded from flash memory is correct for the hardware set.

• The analog input hardware includes precision reference voltages in each scan. Measured values are compared against expected values and are used to confirm the health of the A/D converter circuits.

• Details of the individual diagnostics are available from the ToolboxST application. The diagnostic signals are individually latched, and then reset with the RESET_DIA signal if they go healthy.

FREQUENTLY ASKED QUESTIONS:

What is the GE IS220PPDAH1B?

It is a Power Distribution System Feedback I/O Module that mounts directly onto power distribution terminal boards to monitor 28 VDC power rails, branch circuit currents, and fuse status via dual IONet Ethernet channels.

What terminal boards connect with the Power Distribution System Feedback I/O Module?

The pack plugs into 28-pin interface connectors on power distribution terminal boards such as the BPDAH1A, PPDAH1A, and associated Mark VIe power distribution boards.

How does the Feedback I/O Module alert operators to a blown fuse or voltage failure?

The pack continuously samples voltage and continuity across each branch fuse. When an open fuse or abnormal voltage drop occurs, it immediately transmits a detailed diagnostic alarm over the IONet network to the GE ControlST workstation.

Where can I buy a GE Power Distribution System Feedback I/O Pack?

The IS220PPDAH1B is available for immediate purchase from World of Controls in UNUSED surplus and REBUILT conditions, fully bench-tested and backed by warranty coverage.
