About the IC3600TDTA1
The IC3600TDTA1 is a Differential Trip Card component manufactured by GE for the Mark I and Mark II series of Speedtronic gas/steam turbine management. These were the first of the Speedtronic management systems developed and released by GE, and both systems focused on improving the efficiency of heavy-duty turbines, regardless of the complexity or size of the system. And while the MKI and MKII are now considered obsolete and are no longer supported by GE, both are still used in many facilities around the world for the management of heavy-duty turbine systems as complex as full multi-turbine power stations (up to 400 Mw) down to single 4000 hp units, and all types of systems in-between.
The IC3600TDTA1 is designed with an attached front panel. This panel has three openings, one round and two oval shaped. The round opening gives access to a trim potentiometer that is attached to the board. This opening is labeled “balance.” The panel also includes two red LEDs, one which is labeled A.C. Fault and the other which is labeled D.C. Fault. The front panel connects to the board using two screw mounts.
The IC3600TDTA1 is built with three potentiometers (one already mentioned above,) five ceramic capacitors, one polyester vinyl capacitor, and five capacitors of other material, including a fixed vacuum capacitor. Resistors may be metal film or carbon composite and are often mounted vertically. Diodes tend to be ceramic.
The IC3600TDTA1 includes four transistors of two different designs. The board has five integrated circuits. The board is marked with the round GE USA logo, with the codes 277A3644, 002/03, 006/04 and “WMH.”
