About the IC3600QSPA103A122A
The IC3600QSPA103A122A is a printed circuit board (PCB) manufactured by General Electric (GE). This product is called a potentiometer board. A potentiometer may also be called a variable resistor. The IC3600QSPA103A122A printed circuit board was created as a part of the Mark I-II (MKI-MKII) series. The Mark I and Mark II are the earliest two incarnations of the Mark series. These series were created to control both gas and steam turbines.
The IC3600QSPA103A122A prominently features four large components. These components are relays, or contactors. Each of the relays is rectangular. They are made of gold metal with white labels on the top and grey on the ends. Each relay’s label contains the part numbers CR120G40B06FC and 68A997277C03. These relays contain a voltage of twenty-eight volts Dc (28 VDC). The labels also feature the manufacturer’s name, General Electric as well as GE’s symbol. These four relays are connected to the surface of the circuit board with many wires in different colors such as yellow, red, and green. The IC3600QSPA103A122A features a series of seventeen (17) medium-sized resistors. The resistors are solid grey in color. The resistors are labeled with initials ranging from R10 to R28. The IC3600QSPA103A122A also features four (4) small diodes. These diodes are solid red. They are labeled with designators from CR1 to CR4. A long series of large metal prongs is lined up along the right edge of the IC3600QSPA103A122A. The numbers five (5) to fifty (50) are labeled on the right edge of the IC3600QSPA103A122A. These numbers are printed in yellow writing.
