General Electric created the IC3600SSLA1C to be a component in the Mark I-II turbine control system. The Mark I and Mark II are the first series in the Speedtronic Mark line. The IC3600SSLA1C is a printed circuit board with a large metal plate connected to the side. The IC3600SSLA1C is what called a setpoint control card.
On the left half of the IC3600SSLA1C there are four (4) solid blue potentiometers. Potentiometers may also be called variable resistors because they feature dials that can be used to adjust the resistance of the device. Many resistors are featured on the IC3600SSLA1C. The resistors are brown in color and they have bands in various colors like black, brown, red, and yellow. Also featured on the surface of the circuit board are several small black transistors. A series of white and green wires can be seen on the IC3600SSLA1C. The metal plate that is connected to the printed circuit boards features two large knobs which are grey in color. These knobs are dials that are able to be adjusted. The numbers zero (0) to ten (10) are located around the outside of each knob. This metal plate is contains the label OVERSPEED TEST. There are a few empty holes or spaces available on the plate which could be used to add other components. These available spaces are labeled as SETPOINT ZERO, SETPOINT GAIN, SERVO GAIN, and SERVO ZERO. A collection of capacitors in various sizes and colors are positioned all over the IC3600SSLA1C. A series of metal prongs is aligned on the right side of the IC3600SSLA1C. They are used to connect the PCB to the rest of the turbine control system.
