The IC3600STDC1H is a PC timer board manufactured by GE or General Electric for their Speedtronic Mark I and Mark II series. These two series, introduced in 1969 and 1973 respectively, have been relied on for quality turbine management for nearly five decades. The IC3600STDC1H is a printed circuit board or PCB. The Mark line automates turbine processes and provides for the safety of the turbine equipment and operators.
The IC3600STDC1H timer board may be connected in to other parts in the turbine control system with a series of metal prongs which is aligned along the right side of the board. These prongs are labeled with numbers from 1 to 51, typically increasing by fives. On the opposite side of the IC3600STDC1H, four (4) potentiometers can be found. These potentiometers, or variable resistors, are light blue and contain adjustable dials used to change each device’s resistance. Two (2) integrated circuits are positioned directly in the center of the IC3600STDC1H. These integrated circuits are labeled with their part numbers in white writing. An integrated circuit is a self-contained network of components which can be added to a printed circuit board in order to save space. The IC3600STDC1H also contains a number of light-emitting diodes or LEDs. Four LEDs are located on the left edge of the PCB. Each of these LEDs is paired with one of the blue potentiometers. A variety of different capacitors can be seen on the IC3600STDC1H. Some of these capacitors are solid black while others are solid yellow.
