The IC3600LRDJ1A is a GE FANUC component manufactured for the Mark I or the Mark II series. The MKI/MKII were the first commercially released Speedtronic series from General Electric for gas/steam turbine management. Both series were designed for easy adaptability and scalability. They have been used for decades on heavy-duty turbine systems as diverse as a 400 Mw combined cycle power station with many turbines down to a single 4000 hp turbine at use on an offshore marine platform. In either situation and in systems scaled between these extreme examples, the MK/MKII can control the turbine system, manage its maximum output and keep it to within that unit’s capability, sequence the turbine’s startup and shutdown procedures, protect the turbine and its auxiliaries with a fail-safe protection system that is independent of the controls, annunciate and monitor malfunctions, and power the system.
The IC3600LRDJ1A is a small board with many components. However, this board labels multiple components as if they work as a single unit. For example, one line of sixteen transistors is notated as “Q1.” Two lines of eight transistors are notated together as “Q2.” The board is built with metal film transistors in six lines of sixteen each, but the board is notated as having only R1, R2, R3, R5, R7, and R9 since each line is denoted as a single resistor. The board does not have any notation for R4, R6 or R8. And while C3, C4, and C5 are all individual capacitors, C1 consists of a line of sixteen capacitors made of polyester film. There is no C2 on the board.
The IC3600LRDJ1A has fifty-one pins located along one edge. These pins wire into the larger Speedtronic system and allow for communication. Technical support for this part, including manuals and data sheets, was provided by GE.
