Product Description

The IS200EDEXG1B is a GE PCB component made for the Mark VI series.  The Mark VI is part of the Speedtronic line of steam/gas turbine management systems produced by GE since 1969 when the Mark I was first released.  

The IS200EDEXG1B functions as an Exciter De-Excitation board.  It is the primary board in the de-excitation module and provides conduction sense feedback and de-excitation SCR firing.    The IS200EDEXG1B is usually controlled by the  EXTB board, but it can initiate de-excitation on its own if control fails.  

The IS200EDEXG1B is built with eight high voltage electrolytic capacitors.  The board has two relays, over fourteen transistors, and two heat sink components to dissipate heat more quickly.  The board has over fifteen bias jumpers.  Several of these metal components are connected to each other using surface wiring.  The board has two male vertical pin connectors placed along one edge, as well as four plug connectors.  The board has multiple integrated circuits.  It has six light-emitting diodes, including two red and four green.  These are placed in a line near the high voltage electrolytic capacitors.  The board is populated with metal film resistors and capacitors of various materials.   All corners are factory drilled.
