Product Description

The IS200GGXIG1A is a Mark VI board component.  This circuit board is manufactured by General Electric for use within Innovation Series board racks in the Mark VI system.   The MKVI is part of the Speedtronic line of gas/steam turbine management that was developed beginning with the Mark I and continued for decades through the creation of the Mark VIe.  The Mark VI includes a central Control Module that is responsible for the majority of system control, monitoring, and protection. This module can be created in Triple Redundant or Simplex form.

The  IS200GGXIG1A is an Expander Load Source Board.  This board provides control and isolation between the high-voltage power bridge and connections to cards on the Innovation Series board rack like the (BPII) and the (BICI.)  The IS200GGXIG1A converts RS422 signals to fiber-optic signals in order to gate the bridge IGCT switching devices. The IS200GGXIG1A can connect to up to twelve power devices.  

The  IS200GGXIG1A is built with many I/Os to connect with other boards.  This includes power supply inputs for the GGXI board (J1 through J4,) power output and feedback connectors (J10 through J12,) voltage feedback (J15 and J16,) and fiber-optic connectors.  The board also has connectors that are designed to communicate with specific boards. JFBK connects to the BICI board. JGATE connects to the BPII board. J5 monitors control power to the GDPA board.   The board has grounding stabs (LCOM and DCOM) for quiet and noisy circuits.

The  IS200GGXIG1A has an isolated serial ID chip.   The board also includes fourteen TP test points, nine LEDs, and various capacitors and resistors.  The board has no adjustable hardware devices or fuses.
