IS2020JPDCG01 - JPDC Power Distribution Board | GE Mark VIe | B7B

IS2020JPDCG01 is a General Electric JPDC Power Distribution Board for GE SPEEDTRONIC™ Mark VIe control systems. The JPDC 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.

The IS2020JPDC Power Distribution Module combines the functions of several earlier designs (JPDM, JPDB, and JPDF) to distribute 125 V dc, 115/230 V ac, and 28 V dc power to other boards in the control system from a single module. It hosts a Power Distribution System Feedback (PPDA) I/O pack and can receive diagnostic feedback from up to four additional core power distribution boards. This IS2020JPDCG01 is the standard version for most applications (the IS2020JPDCG02 variant adds a wire jumper permitting the JD2 Battery B input to be used as an output). Board dimensions are 17.2 cm wide x 48.26 cm high (6.75 in x 19.0 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.
