GE IS200GGXDG1ABB Expander Diode Source Board
Product Details:
The IS200GGXDG1ABB is an Expander Diode Source Board designed for GE's Mark VI Turbine Control System, part of the Speedtronic series. Introduced as a significant upgrade from the Mark V, it supports gas, steam, and wind turbines, leveraging patented Speedtronic technology. Mounted in the control cabinet, it facilitates analog and fiber-optic feedback between the Bridge Interface Control Board and diode sources or dynamic braking circuits.
Features:
RS-422 transceivers for gating command interfacing with the BICI.
High-frequency voltage input handling from the Gate Driver Power Assembly board.
Seven stab-on connectors for grounding.
Three LED indicators, DS1 for P5 OK, DS2 for GDPA OK, DS4 for 115V OK for fault diagnosis.
Four duplex connectors for status feedback/firing commands.
Multiple pin connectors: J1 (20-pin to NATO board), J2 (6-pin to GDPA), J3 (2-pin for 115VAC power), PRSC (50-pin I/O to BICI).
This board enhances system reliability with diagnostic capabilities and supports diverse power generation environments. A revision of the IS200GGXDG1A, it offers customizable settings via Berg and wire jumpers.
