The IC3600STDC1H1C what is known as a Fanuc time delay board. This is a component of the Mark I and Mark II series manufactured by General Electric or GE. The Mark I, released in 1969 and the Mark II released in 1973 were the initial two series made for the Mark line of turbine management equipment. The IC3600STDC1H1C is a printed circuit board or PCB which has a variety of different electronic components.
Four (4) blue potentiometers are spread out along the left side of the IC3600STDC1H1C. Also known as variable resistors, these components contain knobs which are made to adjust the resistance of the potentiometers. Directly adjacent to each blue potentiometer, there is a large red LED or light-emitting diode for a total of four LEDs. Four (4) smaller potentiometers which are brown can be found on the IC3600STCD1H1C. These brown potentiometers also contain adjustable knobs. Two (2) integrated circuits are positioned directly in the center of the IC3600STDC1H1C. A self-contained network of tiny components is inside each integrated circuit. One of these integrated circuits is labeled with the part number 7659-38 8250. The other integrated circuit features the part number R8250 68A9136 P026. Situated on the right half of the board, there are four (4) light yellow capacitors which are arranged in a vertical line spanning the length of the IC3600STDC1H1C. Sitting next to one of these capacitors is an orange MOV or metal oxide varistor which is round. Placed in the center of the IC3600STDC1H1C, there is another of these orange MOVs.
