Connectors and Terminals
The GE DS200EXDEG1A DS200EXDEG1AEA Excitation Control Board uses one 64-pin DIN connector for backplane communication. This connector exchanges all feedback and command data with the main processor. Three 25-pin D-sub connectors handle field wiring for analog inputs and outputs. A 9-pin D-sub connector provides a serial interface for configuration. Eight green LEDs indicate valid signal presence on each analog input channel.
Control Algorithms and Protection
This excitation board implements PID control loops for voltage regulation. The board also includes overexcitation and underexcitation limiting functions. Moreover, the GE DS200EXDEG1A DS200EXDEG1AEA Excitation Control Board integrates loss of sensing protection. This feature transfers control to backup voltage regulation during PT failure. A red LED illuminates during any fault condition or limit violation. The board also provides a summary fault relay output.
Energy Storage and Environmental Ratings
This control board contains small electrolytic capacitors on analog input filters. These capacitors store approximately 0.5 joules of energy at full voltage. Therefore, the board retains minimal energy after power removal. The GE DS200EXDEG1A DS200EXDEG1AEA Excitation Control Board operates from 0°C to +55°C ambient temperature. Use shielded twisted-pair cables for all analog signal connections. Configure input ranges using DIP switches before applying power. Do not exceed maximum input voltage ratings under any condition.
