IS200JPDSG1A - JPDS Power Distribution Card | GE Mark VIe | B7B

IS200JPDSG1A is a General Electric JPDS Power Distribution Card for GE SPEEDTRONIC™ Mark VIe control systems. The JPDS function supports core 28 V dc power distribution operation in turbine control and balance-of-plant applications that use the Mark VIe Terminal Board and I/O Hardware. It should be matched to the installed catalog number, hardware form, and cabinet configuration before it is used as a replacement.

GE documentation identifies JPDS as a board that receives 28 V dc power from chosen supplies and distributes it to system controllers and branch circuit I/O pack power distribution boards. Unlike JPDM, JPDS has no fuses or switches and is designed for Class I Division 2 applications; it can maintain three separate power buses for R, S, and T controls, or be jumpered to provide a single bus with redundant supplies. JPDS integrates into the PDM system feedback offered through the PPDA I/O pack. It should be matched with compatible hardware such as the JPDB, JPDF, and JPDE power distribution family, and the DC-62 connector is documented as compatible with the IS220PPDA I/O pack, where that pairing is used in the site configuration.

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.
