More Information

Overview Manuals Board Matching Feedback Routing Health Checks Network Setup

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.

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.
Description
General Electric IS420PPDAH1B is a PPDA power-distribution diagnostic feedback I/O pack for Mark VIe control. It accepts status signals from as many as six power-distribution boards, conditions those signals, and transfers the resulting feedback to the controllers through redundant Ethernet connections.

The IS420PPDAH1B pack mounts on a JPDS or JPDM 28 V dc control-power board. It receives power through the host-board side connector, includes soft-start inrush control, and can collect supported feedback from JPDB, JPDE, and JPDF boards over the ribbon-cable chain.

Cable order is a defined installation constraint for IS420PPDAH1B: the PPDA pack must occupy the end of the power-distribution feedback chain. One pack with one or two Ethernet cables supports a simplex arrangement, while a triplex installation uses three packs to maintain the documented TMR signal path.

Electronic IDs allow IS420PPDAH1B to identify the connected distribution boards and populate the IONet configuration. Startup and background diagnostics cover RAM, flash, processor, Ethernet links, internal power rails, identity matching, application code, and the analog-to-digital reference used for feedback measurements.

Technical notes
General Electric IS420PPDAH1B mounts on a JPDS or JPDM host board and occupies the end of the power-distribution ribbon-feedback chain.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
At what point in the feedback ribbon chain must IS420PPDAH1B be installed?
Place IS420PPDAH1B at the end of the power-distribution feedback chain after the supported source boards.
Which host-board position supplies IS420PPDAH1B with 28 V dc?
IS420PPDAH1B mounts on a JPDS or JPDM board and receives power through the host-board side connector.
How many distribution-board feedback sources can one IS420PPDAH1B consolidate?
One pack can collect status from as many as six supported JPDB, JPDE, or JPDF boards before IS420PPDAH1B transfers the data to IONet.
What changes in the IS420PPDAH1B hardware arrangement between simplex and TMR feedback?
Simplex feedback uses one IS420PPDAH1B, whereas the documented TMR arrangement uses three coordinated packs.
If IS420PPDAH1B reports an identity mismatch, what should be compared first?
Compare the JPDS or JPDM host, ribbon-chain order, connected board IDs, and loaded application code with the configured IS420PPDAH1B hardware set.
When Ethernet status is normal but feedback values remain invalid, which IS420PPDAH1B checks are relevant?
Review the internal power, electronic-ID, processor, application-code, and ADC-reference diagnostics reported for IS420PPDAH1B.
