General Electric, or GE, produced the IC3600STKH1B temperature control circuit board as a part of the Mark I-II turbine management series. The Mark I and Mark II are the earliest series in the Speedtronic Mark line. These series have been relied upon for safe and efficient gas turbine operation for the last fifty (50) years.
A black rectangular relay is located at the top of the IC3600STKH1B board. Relays are sometimes referred to as contactors. This relay has grey pieces on each of its ends. Situated on the left of the IC3600STKH1B are four (4) blue potentiometers. Each potentiometer contains a small metal knob which can be used to adjust the resistance of the device. Potentiometers are often called “variable resistors”. Many capacitors in various sizes and colors are featured on the IC3600STKH1B. A single silver capacitor is found in the center of these four (4) potentiometers. Many yellow capacitors can be found all around the IC3600STKH1B. Close to the bottom right corner of the IC3600STKH1B, there is a capacitor which is dark blue. A variety of capacitors which are dark red but may be either round or rectangular are featured in different positions on the surface of the IC3600STKH1B. Several transistors are located on the IC3600STKH1B. These may be either silver and round or black and smaller in size. Many of the resistors on the IC3600STKH1B are red with multicolored bands sit among the board’s other components. A variety of resistors, diodes, capacitors, metal prongs and other components fill the remaining space on the IC3600STKH1B.
