Description
GE IS200EACFG1B
Product Overview
The GE IS200EACFG1B is a high-reliability Exciter AC Feedback Board designed for GE’s EX2100 Excitation Control System, widely used in power generation, oil & gas, and heavy industrial environments. As a critical interface component, this module measures and processes AC voltage and current signals from the exciter’s Potential Power Transformer (PPT), providing real-time feedback to the control system for precise voltage regulation and fault detection 156.
Featuring dual three-phase voltage transformers (T1-T4) and two flux/air-core coils, the IS200EACFG1B supports up to 480Vrms input voltage and 50/60Hz frequency 25. Its robust design includes DB9 connectors (J504, J509, J514) for seamless integration with the EX2100’s EMIO (Exciter Master Input/Output) boards, enabling microsecond-level signal transmission over 90-meter shielded cables . The module’s compact form factor (33.02 cm × 10.16 cm) allows for flexible mounting in auxiliary cabinets, with conformal coating to mitigate EMI/RFI interference and protect against dust and moisture .
With compatibility with GE’s ToolboxST software, the IS200EACFG1B enables remote configuration of measurement thresholds and diagnostic parameters. Its -30°C to +65°C operating temperature range and IP54 ingress protection ensure reliable performance in harsh industrial environments, such as offshore platforms or high-vibration power plants .
