The IC3600SIXL1 is what is known as a relay module extender card. This is a type of printed circuit board or PCB. The IC3600SIXL1 is a component in the Mark I-II series by General Electric or GE. The Mark I and II were the first couple of series made for the Speedtronic Mark line made by GE. The Mark series were created to be responsible for the management of gas turbines processes. This includes basic operations, control of fuels and other fluids, and safety considerations.
The IC3600SIXL1 is a medium-sized circuit board which is rectangular. The majority of the space on this printed circuit board is empty. Situated along the right edge of the IC3600SIXL1, there is a very long series of metal prongs which are silver. The numbers one (1) through fifty-four (54) are along the edge in black writing. These numbers typically increase by five (5). The wide middle portion of the IC3600SIXL1 is empty except for the full part number of the devices which is IC3600SIXL1 and the numbers 006/01. A barcode on a white sticker is attached to the IC3600SIXL1 directly underneath the part number. Four (4) different components are placed on the IC3600SIXL1. Two (2) jumper ports are sitting on the left border of the IC3600SIXL1. One is placed at the top and the other is sitting on the bottom. These are labeled as JC and JD respectively. Each of the jumper ports contains two (2) ports. Two (2) blue connector ports have been connected to the PCB in between these two jumper ports. The blue connector ports each contain the part number 218A4637-P2 8946.
