GE IS220PPDAH1B IO Pack 330mm x 200mm Mark VI Input Terminal Board

The GE IS220PPDAH1B is a Power Distribution Feedback Module, an integral I/O Pack of GE’s Mark VIe Turbine Control System Series—architectures deployed in steam, gas, and wind turbine control/management systems. As a successor to the IS220PPDAH1 parent module, it leverages GE’s legacy Speedtronic control technology, a key reason for its demand in industrial automation.

Designed for Mark VIe’s backplane-free, Ethernet-based distributed control, it conditions power distribution board feedback signals, provides Ethernet interfaces to controllers, and uses plug-and-play electronic IDs to auto-identify connected power boards. This data populates IONet outputs for accurate system feedback. Mounted on JPDM/JPDC/JPDS boards with 50-pin ribbon cables for multi-board connections, it supports auto-reconfiguration—enabling easy replacement without manual setup. It is compatible with JPDB/JPDF/JPDE feedback signals and integrates with ControlST/ToolboxST software for configuration and diagnostics.

Key Features
Speedtronic & Mark VIe Integration: Part of Mark VIe, suitable for steam/gas/wind turbines, ensuring reliability in critical power generation setups.

Feedback & Connectivity: Conditions feedback signals, offers Ethernet interfaces to controllers, and connects to up to 6 power boards via 50-pin ribbons. Uses electronic IDs for plug-and-play board identification, auto-populating IONet with accurate data.

Auto-Reconfiguration: Simplifies module replacement—new packs auto-configure, no manual setup needed. Note: Reboots/downloads are blocked during reconfiguration.

Compatibility: Mounts on JPDM/JPDC/JPDS boards; works with JPDB/JPDF/JPDE feedback signals. Aligns with Mark VIe’s Ethernet-based design for flexible distributed/centralized I/O.
