IS200ERRRH1A GE Exciter Regulator Redundant Relay

Description:

IS200ERRRH1A is a redundant relay for exciter regulators, manufactured by GE as part of the EX2100 excitation system. Its primary function is to drive and monitor the K41 relay, which controls the output voltage of the excitation system, ensuring its stability and accuracy. By managing the K41 relay, IS200ERRRH1A contributes to precise voltage regulation of the exciter.

Additionally, IS200ERRRH1A drives and monitors the K5T module transfer relay. This facilitates seamless control transitions between redundant modules within the excitation system, enhancing reliability and availability. The component also oversees the module transfer SCR, which governs the power output and current regulation of the excitation system, thereby maintaining stability and precision.

Furthermore, IS200ERRRH1A plays a role in monitoring bridge voltage feedback. This feedback is critical as it provides information about the voltage across the silicon-controlled rectifier (SCR) bridge, a key component of the excitation system. Through this monitoring, the component ensures the SCR bridge's stability and optimal performance.
