GE IS220PPDAH1A Mark VIe Power Distribution System Feedback I/O Pack

The GE IS220PPDAH1A is a Power Distribution System Feedback I/O Pack for the Mark VIe control system. It collects feedback signals from compatible power distribution boards and makes the associated data available to the controller through IONet. The pack supports feedback connections from up to six power distribution boards or six feedback signal groups, and provides a second Ethernet interface for redundant network configurations.

Functional Description

The PPDA I/O Pack identifies connected power distribution boards through electronic IDs. This plug-and-play identification allows the pack to associate feedback data with the corresponding boards and publish the information over IONet for use by the control system.

The module is designed to mount on a compatible 28 VDC control power distribution board, including the JPDS, JPDM, JPDG, and JPDC. Pin-to-pin 50-pin ribbon cables connect additional boards to the PPDA, with each connected board supplying one feedback group.

Technical Specifications

Installation and Connection Requirements

Mount the IS220PPDAH1A on a compatible control power distribution board and secure it using the threaded fasteners beside the Ethernet ports. Position the mounting bracket to avoid applying right-angle forces to the DC-62 pin connector between the I/O pack and its terminal board.

Connect the feedback sources using the specified 50-pin ribbon cables, with pin-to-pin wiring from connector P2 on the applicable power distribution board. Connect one or both Ethernet ports according to the system network configuration. When dual connections are used, ENET1 is typically associated with the R-controller network.

The pack includes a soft-start function that limits inrush current when power is applied. ToolboxST may be used for configuration when required by the installed system. Confirm the applicable hardware combination and software requirements before commissioning.

Frequently Asked Questions

Q: How many power distribution boards can the IS220PPDAH1A monitor?

A: It can receive feedback from up to six power distribution boards or six feedback groups. The actual configuration depends on the connected boards and system wiring.

Q: Which power distribution boards are compatible with this I/O pack?

A: The supplied documentation identifies JPDS, JPDM, JPDG, and JPDC as mounting platforms, and JPDB, JPDE, and JPDF as compatible feedback sources. Verify the exact board variant and connector arrangement before installation.

Q: Does the IS220PPDAH1A support redundant Ethernet connections?

A: Yes. It provides two Ethernet interfaces for redundant network configurations. The network assignment and controller connections must match the Mark VIe system design.
