Product Description
The GE IS200EPCTG1A is a PT/CT Terminal Board designed to operate within the GE Mark VI and Mark VIe Excitation Control Systems, specifically within high-reliability environments where precise monitoring of current and voltage is essential. This board plays a critical role in interfacing with both Potential Transformers (PTs) and Current Transformers (CTs), providing safe and accurate signal conditioning, termination, and routing for input to the control system.
It is engineered to connect high-voltage and high-current instrument transformer signals to protection and control electronics within the excitation system. By handling both analog signal scaling and isolation, the IS200EPCTG1A ensures the integrity and accuracy of real-time generator measurements used for excitation control and protection.
With its robust design and dependable terminal architecture, this board is widely deployed in power generation environments, from traditional thermal plants to hydroelectric and renewable sources. Its modularity, ease of installation, and stable performance make it an ideal choice for both new installations and retrofit applications.

Frequently Asked Questions (FAQ)
1. What is the primary role of the IS200EPCTG1A?
Its main function is to connect and condition voltage and current signals from PTs and CTs to the exciter controller.
2. Can this board be used in GE non-excitation systems?
It is specifically optimized for GE Mark VI and Mark VIe excitation systems but may be adapted in some turbine or generator configurations.
3. Is there signal scaling or conversion done on this board?
No active signal processing is performed; the board primarily provides terminal connections and isolation paths.
4. How many phases can it monitor?
It supports three-phase inputs from both potential and current transformers.
5. Are the terminals labeled for easy wiring?
Yes, all terminals are clearly labeled for voltage and current connections, easing field installation and service.
6. Is there onboard diagnostics on this board?
No. This is a passive terminal board with no active diagnostics or indicators.
7. Does it require cooling?
No cooling or ventilation is necessary under standard operating conditions.
8. What type of connectors are used?
The board uses industrial-grade screw clamp terminals for secure and reliable connections.
9. Can this be replaced in the field without recalibration?
Yes. Since it is a passive interface board, it does not require calibration.
10. Is it resistant to moisture and dust?
Yes. It is coated with conformal coating to protect against moisture, dust, and industrial contaminants.
