IS200ISBDG1A

Product Description

The IS200ISBDG1A is a board component for the Mark VI system.  The Mark VI was one of the last Speedtronic gas/steam turbine management systems created and released by General Electric.  Speedtronic systems were used for heavy-duty turbine management from the 1960s (in the form of the Mark I system) on through to the 2000s.   The Mark VI built upon the strengths of previous systems, like triple redundant backups used in the Mark IV and Mark V systems, and improved upon them using new technology, such as Ethernet communications and a PC-based Operator interface.  

The IS200ISBDG1A is an Insync Delay Board.  This board is drilled in two corners. Each corner also has a terminal connection.  The terminal connections are labeled E1, E2, E3, and E4. The board has five additional connectors, including a male vertical pin ribbon connector (P5) a two-position terminal strip (P4) that is labeled ‘24 VDC Input,’ and three additional connectors.  These connectors are labeled P1/ ‘Full Duplex,’ P2/’XMIT Out,’ and P3/’RCV In.’ All five connectors are placed on board edges.

The IS200ISBDG1A is built with several integrated circuits.  It has one DATEL dc/dc converter component. The board has TP test points, two light emitting diodes, and two small transformers.  The LEDs are labeled as ‘carrier detect’ and ‘power.’ The board has resistors primarily made of metal film and capacitors of electrolytic material and of ceramic material.  

The board is marked with its ID number, with the code ‘6BA01’ and with reference designators to identify components.
