IS2020JPDBG01 - JPDB AC Power Distribution Module | GE Mark VIeS | B7B

IS2020JPDBG01 is a General Electric JPDB AC Power Distribution Module for GE SPEEDTRONIC™ Mark VIeS Safety control systems. The JPDB function supports ac power distribution operation in turbine control and balance-of-plant applications that use the Mark VIeS 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 JPDB as a board that conditions, monitors, and distributes ac power, featuring two separate ac distribution circuits each rated for 20 A at 115 or 230 V ac, with one fused and three fused-and-switched branch circuit outputs provided per circuit. This module variant, IS2020JPDBG01, uses the IS200JPDBH1A circuit board, which does not provide a connection for an ac source selector; J1 ac power is wired directly to the output branch circuits (i.e., without a source selector). It should be matched with compatible hardware such as the JPDE, JPDF, JPDS, and JPDM power distribution family leading to a PPDA I/O pack, where that pairing is used in the site configuration.

This component is typically considered when troubleshooting Mark VIeS Safety 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.
