GE IS200EPCTG1AZZ Exciter PT/CT Terminal Board
The GE IS200EPCTG1AZZ, also cataloged as the IS200EPCT Exciter PT/CT Terminal Board, operates as a dedicated hardware component for generator voltage and current signal acquisition within GE EX2100 excitation control systems. The board receives PT/CT feedback, performs signal conditioning and isolation, and transfers scaled analog signals to the EMIO interface.
The IS200EPCTG1AZZ is configured as an EPCT terminal interface board for EX2100 excitation applications. The available configuration supports generator feedback measurement through PT and CT input circuits and provides conditioned outputs for excitation regulation processing.

Profinet and Industrial Control Signal Interface Characteristics
The IS200EPCTG1AZZ provides generator feedback interface functions within the GE EX2100 excitation control architecture. The board converts PT voltage measurements and CT current feedback signals into conditioned analog outputs for EMIO board processing.
The module applies signal isolation between measurement circuits and control interfaces. Its analog output scaling supports 0-10 V and 4-20 mA transmission formats used for excitation regulation feedback paths. The hardware design supports deterministic signal transfer between field measurement devices and the excitation controller.
The EPCT board supports I/O density scaling within EX2100 configurations by providing multiple three-phase PT input channels and CT measurement inputs on a single terminal interface assembly. The module can be integrated into simplex and TMR excitation system configurations depending on system architecture requirements.

Field Installation Guidelines
Install the IS200EPCTG1AZZ on the designated EX2100 chassis mounting location and verify terminal assignments before connecting PT and CT field wiring.
Use appropriately rated wiring for generator voltage and current measurement circuits. Maintain separation between PT/CT signal cables and high-current power conductors to reduce electromagnetic interference.
Terminate cable shields according to excitation cabinet grounding practices. Verify CT polarity, PT phase sequence, and terminal tightness before energizing the excitation system.
Inspect board connectors, terminal blocks, and conformal-coated surfaces during installation. Confirm that wiring routing follows cabinet clearance and thermal management requirements.
