I/O management: This board is responsible for managing the input/output signals of multiple terminal boards (such as ECTB, EACF, EPCT, and EXTB).
Signal processing: Supports PT (voltage transformer) and CT (current transformer) signal processing, with an analog sampling rate of 2000 times per second.
Pulse emission: One of its main functions is to send gate pulse signals to the ESEL board through the backplane, which are then transmitted to the EGPA.
Relay driver: includes contact input, output/pilot trip relay driver functions.
Signal Interface Center: As the core I/O interface of the excitation control cabinet, it is responsible for handling the communication between external feedback signals (such as voltage and current sensing) and control logic.
Excitation control: It integrates channels for measuring generator terminal voltage, field current, and field voltage, and provides trigger pulse signals for the thyristor bridge.
The IS200EMIOH1A (or H1AFB) is an Excitation Main I/O board that manages contact inputs, output/pilot trip relay drivers, and PT/CT signals.
