More Information

Overview Manuals Contactor Drive De-Excitation Transfer Auxiliary Contacts Trip-Chain Testing

Features:

  • Matches the EXHS G4 simplex breaker-mode configuration.
  • Uses both the 41T trip relay and the 41 close relay.
  • Conditions breaker, field-flashing and de-excitation status for EMIO.
Pilot relays on the board operate 41, 41T, 53A, 53B and KDEP control paths.

Contacts 41, 53A and 53B use a 70 V dc wetting supply for status feedback.

The G4 application must not be replaced with an EXHS group intended for contactor mode or redundant control.

Apter Power supports G4 configuration review, sourcing and documentation for the General Electric IS200EXHSG4A Exciter High-Speed Contactor Driver Board for GE EX2100 excitation-control service.

Contactor Drive for IS200EXHSG4A

  • Application: G4 is used with simplex control and a breaker-mode field circuit.
  • Close function: The 41 close relay is included in this group.
  • Trip function: The 41T trip relay is also used for breaker control.
  • Control path: EMIO commands reach the pilot-relay circuits through the exciter backplane.

De-Excitation Transfer for IS200EXHSG4A

  • Initiation: The controller provides the de-excitation command through EMIO.
  • Relay path: KDEP supports the de-excitation relay interface.
  • Status return: EDEX de-excitation indications are conditioned before returning to EMIO.
  • Protection result: Breaker opening and discharge control are coordinated in the trip sequence.

Auxiliary Contacts for IS200EXHSG4A

  • Monitored points: Contacts 41, 53A and 53B are brought into EXHS.
  • Wetting supply: The contact inputs are powered with 70 V dc.
  • Flashing paths: Pilot relays control the 53A and 53B flashing contactors.
  • Feedback: Conditioned contact states are sent to EMIO for monitoring.

Trip-Chain Testing for IS200EXHSG4A

  • Configuration: Confirm the installed board is the G4 simplex breaker-mode group.
  • Relay proof: Test the 41 close, 41T trip, 53A, 53B and KDEP pilot paths.
  • Input proof: Verify wetting voltage and returned status for all three monitored contacts.
  • System proof: Confirm EDEX and crowbar status reaches the assigned EMIO channel.
Description
The General Electric IS200EXHSG4A Exciter High-Speed Contactor Driver Board is the pilot-relay and status interface for a simplex, breaker-mode EX2100 field circuit. Group G4 uses both the 41T trip relay and the 41 close relay.

Breaker close, breaker trip, field flashing through 53A and 53B, and KDEP de-excitation control are handled by pilot relays on IS200EXHSG4A. The board exchanges these control paths with EMIO through the exciter backplane connection.

Contacts 41, 53A and 53B are wetted by 70 V dc on IS200EXHSG4A. Their conditioned states, together with EDEX de-excitation and crowbar indications, return to EMIO for breaker and trip-chain supervision.

Technical notes
IS200EXHSG4A is the EXHS G4 configuration for simplex breaker mode. Verify both 41T trip and 41 close functions instead of substituting a contactor-mode group.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can IS200EXHSG4A be matched to the existing field controls?
Verify that IS200EXHSG4A is being used with simplex control, breaker mode and both 41T trip and 41 close relay functions.
Why can IS200EXHSG4A close the breaker but return no status?
Check the IS200EXHSG4A 70 V dc contact-wetting path, the 41 auxiliary contact and the EMIO connection.
Why is IS200EXHSG4A not interchangeable with every EXHS group?
IS200EXHSG4A is the G4 simplex breaker-mode group; other EXHS groups use different redundancy or contactor arrangements.
Which relays must be proved after replacing IS200EXHSG4A?
Prove the IS200EXHSG4A 41 close, 41T trip, 53A, 53B and KDEP pilot-relay paths.
What can interrupt IS200EXHSG4A field-flashing operation?
Inspect the IS200EXHSG4A 53A and 53B relay paths, wetting supply and returned contact status.
How does IS200EXHSG4A return EDEX and crowbar status?
IS200EXHSG4A conditions the de-excitation and crowbar indications before sending them to EMIO.
Which records reduce risk during an IS200EXHSG4A replacement?
Keep connector labels, 41/41T assignments, 53A/53B paths and the EMIO interface record with IS200EXHSG4A.
