The IC3600LTDA1C is a printed circuit board (PCB) created by General Electric (GE) as a component in the Mark I-II series for turbine control. Mark I and Mark II were the first two systems created in the Mark series. The Mark I debuted first in 1968. The systems in the Mark series have been controlling the operations of gas and steam turbines for decades. These functions include basic operations such as startup, shutdown, and cooldown as well as fuel and water control. The IC3600LTDA1C is a time delay circuit board.
The IC3600LTDA1C features a wide variety of circuit board components. These components include capacitors, resistors, diodes, transistors, potentiometers and more. Six (6) potentiometers are featured in two rows of on the IC3600LTDA1C. The potentiometers, which are also known as variable resistors, each contain a small metal knob which enables an operator to adjust the resistance of each device. These potentiometers are solid blue and they are situated upright on the surface of the board. A wide variety of capacitors have also been placed on the IC3600LTDA1C. At least nine (9) of these capacitors are solid red and rectangular. These rectangular capacitors are positioned upright on the IC3600LTDA1C. Three (3) yellow capacitors are also featured on the right half of the PCB. Many solid black resistors can also be found throughout the IC3600LTDA1C. A variety of small transistors is featured on the IC3600LTDA1C. Many of the transistors are made from silver metal and circular while others are black and half-circle shaped.
