Features:
- IS420PPDAH1B accepts diagnostic feedback from as many as six supported power-distribution boards.
- The pack mounts on a JPDS or JPDM board and receives 28 V dc through its side connector.
- Dual Ethernet links carry conditioned power-distribution status to the Mark VIe controllers.
IS420PPDAH1B occupies the final device position in the ribbon-cable feedback chain.
Electronic IDs allow IS420PPDAH1B to identify connected JPDB, JPDE, and JPDF hardware for the IONet configuration.
One IS420PPDAH1B supports simplex feedback, while three coordinated packs form the documented TMR arrangement.
The General Electric IS420PPDAH1B Power Distribution Diagnostic Feedback I/O Pack may be available for purchase and technical support from Apter Power.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Supported Power-Distribution Boards
- Host position: The pack mounts on a JPDS or JPDM control-power board.
- Feedback boards: JPDB, JPDE, and JPDF feedback signals are supported.
- Capacity: One pack can receive status from as many as six distribution boards.
- Electronic identity: Automatic discovery uses each board's stored ID to build the IONet hardware list.
Power Feedback Signal Path
- Input path: Distribution-board status travels through the ribbon-cable feedback chain.
- Pack position: PPDA must be installed at the end of that chain.
- Conditioning: The pack conditions the collected signals before network transfer.
- Controller path: Dual Ethernet links carry feedback to the Mark VIe controllers.
Built-In Diagnostic Coverage
- Memory tests: Startup checks cover RAM and flash memory.
- Communication tests: Ethernet links and processor operation are monitored.
- Power checks: Internal supply rails and the ADC reference are verified.
- Configuration checks: Electronic IDs and application code are checked for compatibility.
Simplex and TMR Network Setup
- Simplex: One PPDA pack uses one or two Ethernet cables.
- TMR: Triplex feedback is built with a three-pack set.
- Power entry: The side connection includes inherent soft-start control for the 28 V dc feed.
- Configuration tool: Pack diagnostics and feedback values are available in ToolboxST.
