The IC3600AFGA1B is a FANUC GE board for the Mark I or Mark II systems. This board is designed to function as a Function Generator Board. GE first released the MKI in 1969 and followed it with the MKII a few years later. These systems can operate in temperatures from -50 degrees Celsius to +50 degrees Celsius. They can manage turbine systems rated from 4000 hp for a single unit to multiple units with combined cycles of 400 Mw. The MKI/MKII are used in a variety of environments, including utility, pipeline, and marine processes, with many systems used in offshore applications. The IC3600AFGA1B is built with two circuits. These circuits are placed near the centerline of the board. Each circuit is an operational amplifier with low input currents and extremely low offset voltage, which makes it possible to eliminate offset adjustments. The board has twelve transistors. This includes several Motorola 2N5322K transistors, which are rated for small-signal-medium-power applications. The IC3600AFGA1B is built with a set of spare PTH or plated through-holes. The board has two potentiometers, which are both trim potentiometers. Resistors in the board are primarily five-band fixed carbon film. The IC3600AFGA1B has been drilled in two corners. It is marked with its board number, with the code 006/04, and with the GE mark. It is marked ‘AB’ in one corner. The board has twenty-five individual right-angled pins located along one edge, which all face toward the board edge. The board is numbered by tens from ten to fifty under these pins.
