core functionality

Phase logic bridge: As an interface between process control phase logic and batch processing execution, it controls the state transition and cross regional communication of sequence routines.
Excitation system coordination: In the EX2000 system, participate in the magnetic field control of the brushless exciter to ensure the stability of the unit voltage and reactive power.
Status visualization: 18 LED indicator lights (3 sets x 6) display phase and system status in real-time, facilitating fault diagnosis.
Redundancy adaptation: Supports the triple modular redundancy (TMR) architecture of the Mark V system, with each servo valve coil corresponding to an R/S/T phase interface.
