General Electric, or GE, created the Mark I and Mark II. These systems were the first two systems made for the Speedtronic Mark series. The Mark I was initially created in 1967 and later and introduced to commercial operators in 1969. Ever since then, the Mark series has been tasked with controlling of gas turbines in a variety of industries around the globe. The Mark both maintains and automates gas turbines both efficiently and safely.
The IC3600SCBB1B is only one of approximately 50 printed circuit boards which are included on every Mark I panel. Numerous small metal components can be seen on the surface of the IC3600SCBB1B. A long series of metal prongs is lined up on the right half of the IC3600SCBB1B. These metal prongs are used designed to connected the IC3600SCBB1B PCB to the rest of the components of the Mark I-II system. A collection of 40 small metal components are lined up in rows on the surface of the IC3600SCBB1B. These cube-shaped components allow the board to be wired into the system. There are 7 short white wires which connect a few pairs of these metal cubes to each other. The IC3600SCBB1B also has 1 metal wire at the top of the PCB. This wire also connects two components together. The IC3600SCBB1B features a variety of letters printed on its surface from A to Y. These letters are printed in yellow writing. A range of numbers is also featured on the IC3600SCBB1B. The components on the IC3600SCBB1B can be identified by these letters and numbers.
