About the IC3600EPZU1F
The IC3600EPZU1F is a GE FANUC component built for the Mark I/Mark II from General Electric. Both systems were developed by GE--the MKI in 1969 and the MKII in 1973--for the management of gas or steam turbines. Both systems are designed for use on turbines of varying size, from single unit 4000 hp systems up to power stations that have turbines with combined cycles of 400 Mw. These two early Speedtronic systems have a history of use in temperatures ranging from -50C to +50C, and manage all aspects of the turbine, from startup to sequencing, to protection and power.
The IC3600EPZU1F is built with the GE trademark stamped on the board. One edge is marked with the board id number, with “006/01” and with “PDA.” On another edge, the board is marked “EPZU” and “002/01.” A final edge is numbered “1,” “5,” “15,” “25,” “35,” “45,” and “51.” This edge is fitted with twenty-five right-angled metal pins which are used for communication. The pins connect to wires within the Speedtronic frame.
Two wire-wound resistors, one fuse, and five diodes appear on the surface of IC3600EPZU1F. Each resistor is marked on its top edge with its resistance. The board has ten capacitors. Nine capacitors are placed three by three on the board; these are made of an aluminum electrolytic material and are marked with their capacitance. The last capacitor is made of a polyester vinyl material. The final component on the board is a metal oxide varistor. A metal oxide resistor is a type of voltage-dependent resistor. It can be used as a line voltage surge suppressor.
