More Information

Overview Manuals Control Power Paths Wetting Supply Diagnostic Feedback Vibration Application

Features:

  • IS230JPDGH2A separates 28 V control distribution from contact-wetting power.
  • A mounted PPDA pack collects PDM feedback without making JAC1 an ac power outlet.
  • H2A identifies the enhanced-vibration hardware group.
IS230JPDGH2A is the core dc distribution point for downstream packs and JPDH branches.

Its redundant sources require external isolation before they enter the board.

Local and remote loads use different connector groups on the same assembly.

The General Electric IS230JPDGH2A Core Power Distribution Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

28 V dc Distribution

  • Source inputs: JR and JS receive two externally diode-ORed supplies.
  • Remote branches: J1 through J4 feed switched JPDH distribution boards.
  • Local branches: JD1 through JD5 power packs, controllers, or adjacent loads.
  • Current boundary: The shared bus is limited to 40 A at 55 °C and 30 A at 70 °C.

24/48 V dc Contact Power

  • Input pair: JPS1 and JPS2 accept the two wetting-power sources.
  • ORing requirement: External diodes isolate the redundant inputs.
  • Voltage choice: The bus operates at 24 V dc or 48 V dc, not both.
  • Earth centering: Resistors center the floating wetting bus relative to ground.

PPDA Signal Collection

  • Mounted pack: A PPDA I/O pack installs directly on the JPDG board.
  • Auxiliary inputs: P2 accepts feedback from as many as three other distribution boards.
  • Ground-fault path: Voltage feedback supports detection of PDM ground faults.
  • AC sensing: JAC1 reports two ac-channel conditions without distributing ac power.

H2A Installation Boundary

  • Hardware group: H2A is the enhanced-vibration version of the JPDG assembly.
  • Defined use: The vibration enhancement is identified for selected GE drilling applications.
  • Mounting: The assembly installs with the specified DIN-rail or base-bracket hardware.
  • Ambient range: Board operation is specified from -40 to +70 °C.
Description
General Electric IS230JPDGH2A is the JPDG core power-distribution board used in the Mark VIeS PDM architecture. It keeps controller power distribution separate from the contact-wetting supply required by field input circuits.

After external diode ORing, two 28 V dc sources feed the common control bus on IS230JPDGH2A. Switched branches leave the board for remote JPDH assemblies, while another connector group supplies controller packs and nearby loads.

A second power section lets IS230JPDGH2A operate a centered wetting bus at either 24 V dc or 48 V dc. The two wetting inputs are redundant sources for one selected bus voltage; they are not independent outputs for simultaneous voltage levels.

Power-system feedback reaches the directly mounted PPDA pack on IS230JPDGH2A, including information from auxiliary boards and the ac-sensing connection. The H2A hardware adds the documented vibration-qualified configuration for the specified drilling installation boundary.

Technical notes
IS230JPDGH2A keeps 28 V control distribution, dc wetting power, ac sensing, and PPDA feedback on separate defined paths.

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.
A field circuit on IS230JPDGH2A needs 24 V while another is labeled 48 V. Can both wetting levels be energized together?
No. IS230JPDGH2A has one common wetting bus, so select either 24 V dc or 48 V dc and keep all connected circuits consistent with that choice.
Why can one 28 V source backfeed the other before power reaches IS230JPDGH2A?
The JR and JS inputs on IS230JPDGH2A expect externally diode-ORed sources; missing or incorrect external isolation can create the backfeed condition.
Remote JPDH loads are dead while local controller packs remain powered from IS230JPDGH2A. Which outputs separate those paths?
Inspect the switched J1–J4 branch group for the remote JPDH feeds; the JD1–JD5 group on IS230JPDGH2A supplies local packs and can remain energized separately.
IS230JPDGH2A reports a distribution fault although its main dc bus is present. Which feedback path can influence the diagnosis?
Review the PPDA inputs on IS230JPDGH2A, including feedback arriving from as many as three auxiliary distribution boards and the voltage feedback used by PDM ground-fault detection.
No ac status appears at JAC1 on IS230JPDGH2A. Should an ac load be connected there for testing?
No. JAC1 on IS230JPDGH2A is an ac-sensing connection for two channel conditions; it does not distribute ac power to a test load.
How can a replacement be checked for a vibration-sensitive drilling installation using IS230JPDGH2A?
Verify the complete H2A designation on IS230JPDGH2A and retain the specified mounting arrangement; the enhanced-vibration distinction belongs to that full hardware group.
