IS200JPDDG3A - JPDD Power Distribution Board | GE Mark VIe | B7B

IS200JPDDG3A is a General Electric JPDD Power Distribution Board for GE SPEEDTRONIC™ Mark VIe control systems. The JPDD 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.

JPDD is a dc power distribution board that provides power distribution, isolation, and branch circuit protection for control or I/O functions requiring 125 V dc, 48 V dc, or 24 V dc power, typically supplying dc relay and solenoid control power and contact wetting to TRLY and TBCI terminal boards; it is not used for I/O pack power distribution. Each of the board's six output circuits includes a fuse, a switch, and a lamp indicating output voltage, and only one input voltage level (24, 48, or 125 V dc) can be applied at a time. This JPDDG3A version is supplied with empty fuse holders (grey caps) accepting 31.75 x 6.35 mm (1.25 x 0.25 in) fuses, allowing the fuse rating to be selected for the specific application. JPDD mounts in a plastic holder on a vertical DIN-rail; board dimensions are 23.495 cm high x 10.795 cm wide (9.25 in x 4.25 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.
