IS230JPDGH1B - JPDG Power Distribution Board | GE Mark VIe | B7B

IS230JPDGH1B is a General Electric JPDG Power Distribution Board for GE SPEEDTRONIC™ Mark VIe control systems. The JPDG function supports power distribution operation in turbine control and balance-of-plant applications that use the Mark VIe / Mark VIeS Distributed Control Hardware. It should be matched to the installed catalog number, hardware form, and cabinet configuration before it is used as a replacement.

JPDG distributes 28 V dc control power and 24/48 V dc wetting power to other boards in the control system, and provides sensing circuitry for two channels of ac distribution routed elsewhere. It accepts two separate 28 V dc supply inputs through external diodes and hosts a Power Distribution System Feedback (PPDA) I/O pack, receiving diagnostic feedback from up to three additional distribution boards. JPDGH1A provides standard Mark VIe circuit board vibration protection, while JPDGH2A offers enhanced vibration protection for GE Drilling applications. Board dimensions are 16.51 cm high x 17.8 cm wide (6.5 in x 7.0 in).

This component is typically considered when troubleshooting Mark VIe hardware, replacing a failed module, evaluating repair options, or maintaining spare inventory for turbine control systems. Before installation, verify the catalog number, hardware revision, and associated terminal board or I/O pack configuration against site documentation and OEM requirements. The OEM reference for this listing is GEH-6721 Vol I; GEH-6721 Vol II.
