The GE IS200EXHSG4REC is an Exciter High-Speed Relay Driver (EXHS) board associated with the GE EX2100 Excitation Control system. It provides relay-driving and contact-status interface functions within the excitation control architecture. The board has 8 plug connectors and 2 terminal connectors for its electrical interfaces.

Functional Description

The EXHS board supports relay control functions associated with excitation equipment, including field flashing and de-excitation. It also handles relevant contact-status signals for monitoring by the excitation control system.

In the EX2100 architecture, EXHS interfaces with the Exciter Main Input/Output (EMIO) boards through the exciter backplane. Its functions include conditioning status signals from the de-excitation and crowbar control circuits before forwarding them to the control system.

G4 Configuration

The G4 board configuration is identified as a simplex control arrangement for standard DC contactor applications in the EX2100 excitation system. The EXHS family documentation distinguishes G4 from G2 by its contactor application and control configuration.

The G4 configuration is associated with field breaker control functions, including the 41 close relay and 41T trip relay. Correct configuration identification is important when selecting a replacement board, since the relay arrangement must match the installed excitation circuit.

Relay and Signal Interfaces

The EXHS board performs several relay and monitoring functions:

Relay 41: Associated with field switching control.
Relay 41T: Used for the trip function in the G4 breaker-mode configuration.
Relays 53A and 53B: Pilot relays for field-flashing control.
Relay KDEP: Pilot relay associated with the de-excitation circuit.
Contact feedback: Monitors the status of field switching and flashing circuit contacts.

The board also conditions de-excitation and crowbar status signals before forwarding them to the EMIO control interface. These signals allow the excitation control system to monitor relevant switching and protection circuit states.

Frequently Asked Questions

Q: What is the difference between the GE IS200EXHSG4REC and G2 configurations?

A: Both belong to the simplex EXHS board group. G4 is associated with breaker-mode control, including the 41 close and 41T trip functions, whereas G2 is designed for high-speed contactor applications.

Q: What is the function of the 53A and 53B relays?

A: They are field-flashing pilot relays. They provide relay control interfaces for the field-flashing circuit during excitation startup.

Q: What should be checked before replacing the IS200EXHSG4REC?

A: Verify the G4 configuration, relay arrangement, connector positions, and terminal wiring against the installed EX2100 excitation system. The eight plug connectors and two terminal connectors should be checked against the applicable board wiring documentation before reconnection.
