The IC3600SCBL1 was created by General Electric (GE) to be a part of the Mark I-II system. The Mark I and Mark II were the first two series in the Speedtronic Mark line.Mark I was the first system in the Mark series. The first Mark I unit was installed in New York on Long Island in 1968. The Mark series manages the operations of gas turbines including startup, speed and load control and temperature monitoring. The Mark series also ensures the safety of both the turbine equipment and the people who operate the turbine system. The IC3600SCBL1 is just one of many printed circuit boards which are used in the Mark I and Mark II systems.
The IC3600SCBL1 features several circuit board components. A series of large metal prongs is positioned on the right edge of the PCB. These prongs are used to connect the IC3600SCBL1 to the larger turbine system. On the left side of the center of the IC3600SCBL1, there is a large yellow capacitor. This capacitor is connected with a metal wire to a metal cube at the top edge of the circuit board. This metal cube is one of three that are aligned along the top edge. There are also three of these metal cubes at the bottom of the IC3600SCBL1. These are aligned along the lower edge of the circuit board. These small metal cube-shaped parts help to wire the IC3600SCBL1 into the larger Mark I-II system. The part number of the printed circuit board, IC3600SCBL1, is printed on the top edge of the circuit board in white writing.
