IS200EDFFH3A | General Electric I/O Terminal Board

Description 

The IS200EDFFH3A model is an EX2100 DC Feedback Board that measures field currents and voltages at the SCR bridge and interface in a Simplex system. When in the EX2100 system, it will interface with the Excitation Control Auxiliary Interface board over a fiber-optic link.

Information About IS200EDFFH3A

The IS200EDFFH3A board is labeled an Exciter DC Fanned Feedback Board and is part of the EX2100e Excitation Control Series. The purpose of this board is used to measure voltages and field currents at the silicon-controlled rectifier (SCR) bridge; once the voltages and field currents have been measured, the EDFF board will interface to the EAUX or Excitation Control Auxiliary Interface through a high-speed fiber-optic cable link. There are three different group variations of the EDFF board; as the H3 group variation, this board can only operate in a simplex system.

The IS200EDFFH3A board is used within the High Voltage Interface module. A current shunt is part of the power conversion module and has an mV output signal received by a differential amplifier on this EDFF-abbreviated board. Once the output signal is received from the current shunt, it will provide voltage feedback and DC currents to the controls.

On the IS200EDFFH3A board, there are V-F or voltage-to-frequency converter circuits. One is used for field voltage feedback, one is used for field current feedback, and one is used with up to three redundant sections; these three redundant sections are labeled as controllers C, M1, and M2. The field voltage feedback on this model will provide up to eight selector settings to scale the bridge voltage, depending on the application that the model is used.
