It provides high-fidelity isolation for secondary voltage and current inputs, which are then transmitted to the EMIO board via dedicated cabling. The module supports deterministic data flow, ensuring that potential transformer (PT) and current transformer (CT) values are processed by the control rack in synchronization with the excitation system's scan cycles. When implemented in high-availability environments, the architecture supports the use of three EPCT boards in parallel to ensure data redundancy and continuity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the board support both 1 A and 5 A current transformer (CT) inputs simultaneously?\u003c\/p\u003e\n\u003cp\u003eA: The board hardware is designed to accommodate CT inputs of 1 A or 5 A ratings. Ensure that the specific CT current level is correctly verified against the system loop diagrams to prevent scaling errors in the excitation controller.\u003c\/p\u003e\n\u003cp\u003eQ: Is the auxiliary analog input configurable for different signal types?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the onboard analog input is configurable to accept either voltage or current signal ranges. The final selection depends on the configuration mapped within the excitation control software.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Secure the board to the designated EX2100 cabinet mounting structure. Ensure that the mounting hardware is tightened to provide mechanical stability and a reliable ground reference path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Segregation\u003c\/strong\u003e: Route PT and CT input wiring away from high-voltage AC power cables and PWM-driven motor leads. Use shielded cabling for all analog input signals to minimize electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransformer Termination\u003c\/strong\u003e: Confirm that the 3-phase PT inputs and CT inputs are terminated in the correct phase sequence. Incorrect phase rotation will lead to improper excitation control calculations and potential system instability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Integrity\u003c\/strong\u003e: Inspect the cable connectors interfacing with the EMIO board for bent pins or signs of oxidation. Ensure all cables are fully seated and locked to maintain low-impedance electrical continuity for the isolated signal path.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":52949216264501,"sku":"IS200EPCTG1A","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/IS200EPCTG1AAA_968f4329-0d53-41eb-bd41-343d3e8efceb.png?v=1780302371","url":"https:\/\/www.5gplc.com\/products\/ge-is200epctg1a-exciter-pt-ct-terminal-board","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
