About the IC3600LFAA1

Greater Product Series Information

The IC3600LFAA1 is a Control Counter component created by GE for the Mark I or the Mark II systems. The MKI was released by General Electric in 1969 as part of the Speedtronic line for gas/steam turbine management; the MKII followed a few years later. 

While both of these Speedtronic systems are now considered obsolete due to the release of more technologically advanced Speedtronic systems, many MKI/MKII systems remain in use around the world, working to control turbine systems as simple as single unit 4000 hp systems and as complex as multi-unit 400 Mw (combined cycle) power plants. The IC3600LFAA1 is a GE FANUC component.

Hardware Tips and Specifications

The IC3600LFAA1 is a rectangular board designed with:

• fifty right-angled pins located along the right edge of the board
  • these pins function together as a backplane connector that connects the board into the rack system
• the board is numbered by fives or tens under the pins.  The back surface of the board carries the code “68A9829200G1.” The front surface is marked with the board id number, with the GE logo, and with several reference designators. It is important to note several components may carry the same reference designator.  

The IC3600LFAA1 is built with polyester vinyl capacitors. Most of these are mounted vertically. C10 is mounted horizontally along the mid-line of the board. The board is built with carbon composite resistors as well as resistors of other materials. Most CCRs are mounted vertically. The board has several transistors. Most transistors are located near the left edge of the board and carry a reference designator of Q1, Q2 or Q3.

Technical support for the IC3600LFAA1 was provided by General Electric. Installation procedures may be found in publications such as datasheets, user guides, and manuals that reference this part number.
