About the IC3600QSPA103B104B
The IC3600QSPA103B104B printed circuit board (PCB) was manufactured by General Electric (GE). The IC3600QSPA103B104B is what is called a potentiometer board. Another name for a potentiometer is variable resistor. The IC3600QSPA103B104B PCB was developed to be a part of the MKI-MKII (Mark I-II) series. The Mark I and II systems were the earliest two versions of the Mark series, with the Mark I being introduced in 1968. The Mark series was created to automate the functions of both gas and steam turbines while ensuring the safety of the equipment and the people who operate it.
The IC3600QSPA103B104B features four (4) very noticeable large components. These large rectangular components are relays, otherwise known as contactors. These relays are made of a gold metal and feature white labels on the upper surface and grey pieces on the ends. The label fixed to each relay features the component’s part numbers which are CR120G40B06FC and 68A997277C03. These relays each contains twenty-eight volts DC (28 VDC). The white labels also list the name of the manufacturer (General Electric) and the GE symbol. A series of multi-colored wires connects these relays to the circuit board. The IC3600QSPA103B104B contains seventeen (17) resistors which are solid grey. Two (2) solid red resistors are also featured on the board. The IC3600QSPA103B104B also features (4) small diodes. These diodes are solid red. These small diodes are labeled with the letters CR, from CR1 to CR4. On its right side, the IC3600QSPA103B104B features a series of metal prongs. The numbers five (5) to fifty (50) are listed along the right edge of the IC3600QSPA103B104B in yellow writing.
