IS200JPDFG1A - JPDF Power Distribution Board | GE Mark VIe | B7B

IS200JPDFG1A is a General Electric JPDF Power Distribution Board for GE SPEEDTRONIC™ Mark VIe control systems. The JPDF function supports 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.

JPDF is a 125 V dc power distribution board that accepts redundant 125 V dc battery and/or DACA-converted ac inputs and distributes power to other system boards over a floating dc bus centered on earth, enabling ground-fault detection. The board provides three fused, non-switched outputs and six fused, switched outputs, including dedicated circuits for 125 V dc/28 V dc converters, VPRO/PPRO trip modules, TBCI contact input boards (using built-in 22-ohm source-impedance resistors), and remote JPDD boards. JPDF integrates into the PDM system feedback through a PPDA I/O pack and is compatible with the P1/P2 feedback connectors on JPDB, JPDE, JPDS, JPDM, JPDC, and JPDG.

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.
