IS200GGXDG1A GE Expander Diode Source Board Printed Circuit Board

Product Details:

Description:

The IS200GGXDG1A is a board component of the Mark VI system from General Electric. The Mark VI Series that this IS200GGXDG1A printed circuit board belongs to is really known as the Mark VI Turbine Control System Series in length, as it truly exists with specific functional applications in the control and management systems of General Electric-compatible gas, wind, and steam turbines, specifically. This does represent a significant functional upgrade upon the Mark V Turbine Control System Series of the same that originally preceded this IS200GGXDG1A device's Mark VI Turbine Control System Series, as the Mark V Serie’ s possible functional applications were restricted to gas and steam turbine assemblies alone.

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. This IS200GGXDG1A product is surrounded by at least some amount of originally-printed instructional manual materials online for the purposes of this IS200GGXDG1A personalized product page, which is somewhat atypical to the rest of Mark VI Series products available here.

• DS1 ON for P5 OK signal LED
• DS2 ON for GDPA OK signal LED
• DS4 ON for 115V OK signal LED

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. Each of the quad redundant output drive circuits either energises or de-energises based upon the majority voted data received from the three processing elements. The majority voting scheme provides both fault tolerance and fault detection requiring data, which agrees to precision within specified tolerance, for at least least two out of three (2oo3) processing elements.
