About the IS200TRPGH1BDD

The IS200TRPGH1BDD is a printed circuit card used within the Mark VI Speedtronic system.  This system is one of several manufactured and marketed by General Electric from the late 1960s through the early 2000s for the management of steam or gas industrial turbine systems.  

The IS200TRPGH1BDD is one of the trip solenoid control boards.  This board works in conjunction with a TREG control board within the VTUR turbine protection system.   The IS200TRPGH1BDD provides the negative 125  dc feeder for solenoid trip in the emergency trip system.    The board has nine relays that connect in groups of three to the trip solenoids.  These also have MOVs (metal oxide varistors) located nearby that provide current suppression.   Within gas turbine applications, the TRPG board is responsible for monitoring Geiger-Mueller flame detectors. 

The board is built with two terminal strips with multiple connection points.  These are located along one long board edge.  Along the opposite board edge, there are three D-shell connectors for cable connections.  Between these components, the board has the aforementioned relays, vertical (female) plug connectors, and various integrated circuits, resistors, capacitors, and a few diodes.  

For additional information about the IS200TRPGH1BDD board, please refer to publications provided by General Electric.  These publications (manuals, data sheets, user guides) will give the user access to important information about associated hazards and proper procedures for installation and maintenance of this board. 

AX Control typically ships orders every weekday, Monday through Friday.  Purchase orders received before 3 pm for in-stock merchandise are typically shipped out on the same day.  Some products take longer to ship due to limited availability.
