The IS200TRTDH1C is a circuit board component manufactured by General Electric for the Mark VI system. The Mark VI is part of the Speedtronic family for the management of heavy-duty gas and steam turbines. Mark VI provides alert displays, process variable trends, and point control displays through its operating interface.

The IS200TRTDH1C is used as an RTD input terminal board. Physically, the board consists of two terminal terminals (each with 24 screws connected), two 37-pin cable connectors (female heads), and a bank of capacitors. The board’s code is “6BA00”. There is a shield strip on the left edge that connects directly to the side of the terminal. The board has two factory-drilled oval notches that allow for screw mounting, as well as several notches along the edge of one board.

The IS200TRTDH1C is connected to the VRTD board and communicates via two cable connections. The I/O board converts the TRTD input into a temperature value (in digital form), which is then transmitted to the controller. The IS200TRTDH1C is a simplex board and does not support TMR applications.

The IS200TRTDH1C has no jumper or hardware Settings. However, the board does have a hardware limit check function based on preset high/low levels. It also has a software system limit check for generating alerts; These limits can be configured. Check the resistance of each RTD and compare it to its correct value. If it is high or low, a fault occurs. In addition, each connector located on the board has its own ID device, which creates incompatible failures that do not match.
