Product description

The IS200JPDFG1A is a GE component manufactured as part of the Mark VI system. The system is part of the long-running Speedtronic family created and developed by GE for gas/steam turbine management. Various systems bearing the Speedtronic name have been used for heavy-duty turbine management for over thirty years. Mark VI was one of the last systems to be released and included Ethernet communication and a Windows PC-based operator interface.

The IS200JPDFG1A is part of the IS2020JPDF power module, which consists of a circuit board, sheet metal structure with DC circuit breakers, input filters, current limiting resistors and series diodes. The IS200JPDFG1A provides connectivity for two DACA modules if required. The IS200JPDFG1A board is used to distribute DC power to large capacity DC power. The IS200JPDFG1A uses ribbon cable connections for system feedback, such as DC bus voltage and ground fault detection through the PPDA board.

The IS200JPDFG1A has six toggle switches placed in a line. Three of them included a warning label that read, “Beware, after power failure, wait 30 seconds, then power back on.” The IS200JPDFG1A has 18 fuses with independent power ratings. It has 14 plug connectors, including 2-bit plugs (10), 12-bit plugs (2), 9-bit plugs and 5-bit plugs.

The IS200JPDFG1A includes metal film resistors, box capacitors, ceramic capacitors, TP test points, and transistors. Components are labeled with reference labels. For more information about the board and its components, see GE publication GEI-100613.
