GE DS200TCEBG1ACE 紧急超速板

Product Description
The DS200TCEAG1A is an Emergency Overspeed Board produced by General Electric Multilin for the Mark V series. Also called a Protective Processor, the board primarily works to safeguard the Mark V by making efficient use of the high speed protection circuitry.The Emergency Overspeed Board is also capable of bringing in signals for automatic synchronization, flame detection, low shaft speed, and high shaft speed. The aforementioned signals are scaled and conditioned, and then written to the STCA board over the IONET. TCEA boards can also send emergency trip signals to the TCTG (Turbine Trip Board); if enough relays "vote" to trip the unit, the TCTG board can handle this process.

The hardware configuration is straightforward when referencing the GEH-6153 user manual. Jumpers J31 and J1 located on the TCEA board are both used for testing purposes. The TCEA's jumpers J4-J6 establish IONET addresses for the board. Jumpers J2-J3 provide for IONET termination resistors. J12-J21 jumpers help assign overspeed trip frequency settings, specifcally for the high pressure shaft. Meanwhile, jumpers J8-J11 and J22-J27 provide the same functions for the low pressure shaft. The hardware jumper screen and Appendix A both contain more information on hardware jumper settings. The user manual also has detailed information on the various other jumpers located on the board.
