Product Description

The IS200STURH4AEC from General Electric is designed as a board component for use in the company’s Mark VI or their Mark VIe turbine control systems.  This board works as a simplex primary turbine protection input card and is essentially an S-type (simplex) version of the TTUR board.  The TTUR board is designed to provide a connection to drive the primary trip board within a module.   Mark VI and Mark VIe systems can be used to control a number of different kinds of industrial turbine systems including gas and steam turbines.  The Mark VI/Mark VIe systems can be used for both large, complex systems as well as smaller, more economically designed systems. 

The IS200STURH4AEC is typically used within generator drive systems that need primary and overspeed synching or in mechanical systems that need overspeed protection.  It can also be used in locations where four-pulse input circuits are needed where a PTUR board typically is used.  The STUR board offers the same I/O pack mounting and physical size as the PTUR. 

The IS200STURH4AEC is designed to accept as many as four-speed input signals.  The board has a DC-62 pin connector that allows for the mounting of one PTUR I/O pack.  The board also has a DC-37 pin cable connector that allows the circuit board to connect to boards like the TPRA, TPRS, TPRL, or TPRG.   There is a 48-screw terminal strip along one board edge, as well as two relays mounted to the board’s surface.    The board has been factory drilled along its edges to facilitate mounting options.
