About the IS2020JPDBG01
The IS2020JPDBG01 is an AC Power Distribution Module from General Electric that was created for the Mark VI system. The Mark VI is part of the Speedtronic line of gas/steam turbine management systems that began with the Mark I in the 1960s. The Mark VI was the third of the Speedtronic systems to use TMR (triple modular redundant) architecture, although the system was also available in Simplex form.
The IS2020JPDBG01 is compatible with P1 and P2 feedback signal connectors on JPDS, JPDF, and JPDE boards, as well as JPDM boards leading to a PPDA I/O pack. This module is mounted in a cabinet used by the PDM. It is grounded through metal mounting supports that are fastened to the underlying sheet metal of the module.
The IS2020JPDBG01 have two sources of ac power wired on the ride side of the module through a terminal board. Power goes to ac line filter assemblies located under the IS200JPDB PCB, where a wire harness connects the assemblies to the board’s J1 connector. The module also uses an IS200JPDBH2A board with an ac source selector.
The IS2020JPDBG01 has multiple inputs and outputs, including a terminal strip (TB1,) two 9-position Mate-n-Lok connectors, a 5-position Mate-n-Lok connector, six switched and fused output connectors and two 50-pin diagnostic ribbon cable connectors. Diagnostics for the board are run through both the P1 and the P2 connectors. There are no configuration options for this module.
