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).

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.
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.
