Product Description
The IS200GGXDG1A is a board component of the Mark VI system from General Electric. This board functions as an Expander Diode Source Board. The board provides fiber-optic and analog feedback hardware necessary for interfacing between the BICI board and a dynamic braking circuit.
The IS200GGXDG1A is mounted within the control cabinet. Gating commands and status signals are interfaced using RS-422 transceivers. The IS200GGXDG1A uses power (high-frequency) from the GDPA board. The board’s seven stab-on connectors are used for grounding.
The IS200GGXDG1A has multiple components mounted on its surface. This includes 3 LED indicators, 6 3-terminal connectors, 15 test points, 3 2-terminal connectors, and a 4-pin connector. The board also has a J1 and J2 connector(20 pins and 6 pins respectively) for connections to the NATO and GDPA boards as well as a 50-pin connector that interfaces with the BICI.
The IS200GGXDG1A uses berg and wire jumpers. Berg jumpers are used for burden resistor selection. Wire jumpers control selective grounding. In a typical operation configuration, E1 and E4 will be jumpered together, E2 and E5 will be jumpered together, and E3 and E6 will not be jumpered together. E7 always ties to chassis.
More information about the IS200GGXDG1A, including information on application data, test points, adjustable hardware, I/O connectors, as well as important information regarding replacement procedures and handling precautions can be found within GE data sheets, user guides, and manuals. Please refer to these before beginning any replacement.
