IS210JPDHG1A - JPDH Power Distribution Board | GE Mark VIe | B7B

IS210JPDHG1A is a General Electric JPDH Power Distribution Board for GE SPEEDTRONIC™ Mark VIe control systems. The JPDH 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.

JPDH is a high-density 28 V dc power distribution board that provides power to 24 Mark VIe I/O modules and three Ethernet switches from a single 28 V dc supply, with each I/O module output protected by a positive-temperature-coefficient fuse (1.6 A at 20°C, derated to 0.8 A at 70°C). The 6-pin input connector accepts three separate 28 V dc feeds (R, S, T) for TMR redundancy, and additional JPDH boards can be daisy-chained through the unfused J1X connector to power larger I/O counts. Board dimensions are 15.875 cm high x 10.795 cm wide (6.25 in x 4.25 in), and the board mounts via DIN-rail, card-carrier, or base-mounted steel bracket.

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.
