Functional Description

IS200EXHSG3 is an Exciter High-Speed Relay Driver Board developed by GE. It is part of the EX2100

series. Exciter High-Speed Relay Driver board serves a crucial role within the EX2100 Excitation Control system,

specifically in providing drivers for various components and relays, as well as conditioning and transmitting signals

to other related boards. Exciter High-Speed Relay Driver board plays a pivotal role in the EX2100 Excitation Control

system by providing drivers for various relays, conditioning critical signals, and managing contact inputs. Its communication

with other boards through the backplane facilitates the integration and coordination of crucial control and monitoring

functions within the system, ensuring reliable and efficient operation of the excitation control processes.

Features

• Functionality within EX2100 Excitation Control: Providers drivers for dc contactors
• (41) and pilot relays associated with de-excitation and field flashing functions.
• Connection and Redundancy: These boards are connected to either three IS200EMIO
• Exciter Main Input/Output Boards (EMIO) in a redundant control setup or to a single
• EMIO board in a simplex control configuration via the Exciter Backplane Board.
• Pilot Relays and Signal Conditioning: The board hosts pilot relays for flashing relays
• 53A and 53B, along with pilot relays for the de-excitation relay KDEP. It conditions de-excitation
• status signals from the Exciter De-Excitation Board (EDEX) and crowbar status signals from
• the De-Excitation Control Board before transmitting them to EMIO for further processing.
• Contact Inputs and Monitoring: The board manages three contact inputs from 41, 53A, and
• 53B, which are powered by 70 V dc sourced from EXHS. These inputs are connected to the
• exciter power supply. The board monitors feedback from these contact inputs and relays the
• resulting status signals to the EMIO board for system monitoring and control purposes.
