About the IC3600TDTA1D1B
The IC3600TDTA1D1B is a component for the Mark I or the Mark II series from GE. These were the first two Speedtronic series released by General Electric for the management of heavy-duty steam or gas turbines. Both systems functioned on designs that were adaptable and scalable, and because of this have been used for decades on systems as small as a single turbine--for example, an unmanned pumping station in a remote area--and as large as an entire power plant with multiple turbines (up to 400 Mw.)
Hardware Tips and Specifications
Now considered obsolete by GE and no longer supported by the OEM, these systems are still in use by many facilities around the world. The IC3600TDTA1D1B functions as a Differential Trip Board. It is marked on its surface with several codes and/or information, including the GE round “USA” logo, the board identifier number, the codes “002/03,” “006/04,” “277A3644,” and “WMH.” It is also numbered by fives along one edge. This edge is fitted with a parallel line of metal pins that serves as a communication device between the board and the rest of the system.
The IC3600TDTA1D1B has a narrow silver panel fitted to one long edge. This panel has two LED lights protruding from it, which are labeled “AC Fault” and “DC Fault.” Three openings are located on the panel, including one located in the center that is marked “Balance.” This opening lines up with one of the three potentiometers attached to the board. This panel connects to the PCB via two screw connections. The IC3600TDTA1D1B has three potentiometers (mentioned above,) eleven capacitors, and a number of diodes and resistors. Capacitors may be polyester vinyl, fixed vacuum, or other materials. Most diodes and resistors are mounted vertically. The IC3600TDTA1D1B includes five integrated circuits and four transistors of two designs. Most components on the board are marked with designating lettering/numbering.
