GE IS200GGXDG1ABB Expander Diode Source Board

IS200GGXDG1ABB Expander Diode Source Board

The IS200GGXDG1ABB Expander Diode Source Board (GGXD) provides the fiber-optic and analog feedback hardware needed between the drive's Bridge Interface Control Board (BlCI) and a diode source/dynamic braking (DB) circuit. This board is located in the control cabinet.

RS-422 transceivers are used to interface the gating commands and status signals between the BICI board GGXD board. Fiber-Optic signal interfacing is used between the GGXD board and up to four DB Integrated Gate Commutated Thyristors (IGCTs). The GGXD board receives a high frequency voltage input from the Gate Driver Power Assembly Board (GDPA). Onboard positive 5 (P5) and 12 (P12) V dc power supplies provide power for the RS-422 transceivers, fiber-Optic communications, and some monitoring circuits. Seven isolated stab-on type connectors are provided for selective grounding.

The following signals are sent to the Bridge Interface Conral board (BICI) from the GGXD board:

· Three current feedback signals from the source current transformers

· An opto-coupled GDPA board power supply OK signal

· An opto-coupled circuit continuity checking signal to ensure that the associated Voltage Feedback Attenuator Board (NATO) is plugged in

-This signal is not available for an unpowered GGXD board in a non-DB application.
