IS200EPCTG1A Exciter PT/CT Terminal Board – Precision Signal Conditioning for EX2100

Manufacturer: General Electric — part of the EX2100 series.
Function: Exciter PT/CT Terminal Board (EPCT) for generator voltage and current feedback.
Input types: Two 3-phase PT inputs (115 V rms, 50/60 Hz) and two CT inputs (1 A or 5 A).
Isolation: Onboard isolation transformers provide critical signal separation.
Analog input: One non-isolated channel accepts 0–10 V dc or 4–20 mA (selectable via JP1).

Key Technical Specifications

Model: IS200EPCTG1A — GE part number for the EPCT board.
Power supply: 28 V dc (supplied from the control rack).
PT input rating: 115 V rms ± , with internal fuses; burden less than 1 VA.
CT input range: 1 A or 5 A ac; burden less than 1 VA.
Scaled outputs: Isolation transformers produce 1.533 V rms for 115 V PT input (open delta).
Analog input range: 0–10 V dc or 4–20 mA; cable resistance ≤15 Ω for 300 m max length.
Operating temperature: -30 to 65 °C — suitable for harsh industrial environments.
Dimensions & weight: 23.8 cm x 8.6 cm; 0.45 kg.
Wiring: Accepts #10 AWG to #12 AWG; PT/CT cables up to 1000 ft.

Board Layout and Connectivity

Three terminal blocks: TB1 for PT/CT field wiring; TB2, TB3 for CT shorting protection.
Connectors J305, J308, J315 route signals to EMIO board in simplex or redundant controllers.
Eight test points (TP1–TP8) allow direct monitoring of isolation transformer secondary legs.
Switch configuration on TB1 matches generator PT wiring (wye or delta).
Maximum wire size #12 AWG for PT circuits ensures low voltage drop over 1000 ft.

Measurement Accuracy & Isolation

Generator voltage measurement uses two isolation transformers creating a three-wire open delta output.
Generator current measurement uses dedicated CT isolation transformers preserving signal integrity.
High reliability designs allow up to three IS200EPCTG1A boards in parallel for redundant systems.
Built-in burden <1 VA minimizes loading on PTs and CTs.
Analog input provides 0.1% resolution for 4–20 mA or 0–10 V signals.
