Overview

Common Applications
Product Precautions
GE IS200EXHSG4A is the G4 EXHS board selected when a simplex EX2100 system operates a field breaker rather than a field contactor. The board routes conditioned status to EMIO through the EBKP backplane and carries the pilot-relay functions required for breaker closing, tripping, flashing and de-excitation supervision.
- G4 simplex breaker-mode EXHS configuration
- 41 close and 41T trip pilot-relay functions
- 53A and 53B field-flashing relay control
- 70 V dc wetted contact-status conditioning
The operating chain runs from EX2100 EMIO control logic → EBKP backplane → IS200EXHSG4A pilot and status circuits → Field breaker, flashing and de-excitation equipment; document each boundary and prove the intended final response before release.
Important Notice: Use the complete G4 identity and prove the exciter field circuit discharged before disturbing breaker, flashing or de-excitation wiring.
GE IS200EXHSG4A Manuals & Downloads
GE IS200EXHSG4A Official Technical Reference Excerpt (PDF)GE IS200EXHSG4A Installation & Commissioning Guide (PDF)
The Official Technical Reference Excerpt preserves five applicable EX2100 manual pages covering the EXHS board, G4 breaker arrangement and related field functions. The separate commissioning guide organizes installation, wiring and acceptance checks for this exact spare identity.
Simplex field-breaker control
Operates the EX2100 breaker close and trip pilot functions in G4 applications.
Field flashing sequence
Controls 53A and 53B pilots during generator field build-up.
De-excitation coordination
Conditions breaker and EDEX status used during stored-energy discharge.
Exciter interlocking
Returns 41, 53A and 53B status to EMIO for sequence supervision.
Apply these controls specifically to GE IS200EXHSG4A before isolation, replacement, reconnection, energization and final release.
1
Use GE IS200EXHSG4A only in the documented G4 simplex breaker-mode circuit.
2
Isolate the station battery, breaker control supply and exciter field circuit before handling the board.
3
Verify the complete IS200EXHSG4A suffix against the installed nameplate and controlled drawing.
4
Label the 41 close, 41T trip, 53A, 53B and KDEP circuits before disconnecting wiring.
5
Confirm both 70 V dc wetting-supply paths and their returns before applying control power.
6
Check EBKP and EMIO cabling for keyed orientation, pin damage and secure seating.
7
Do not test field flashing with the generator field connected unless the approved startup procedure permits it.
8
Prove breaker close, breaker trip, flashing status and de-excitation response before releasing the exciter.
Technical notes
Verify the G4 breaker-mode identity, EBKP backplane position and 41/41T field-device wiring against the exciter drawing. Commission close, trip, flashing, de-excitation and 70 V dc feedback paths as separate checks.
FAQ View All FAQ
-
Which EX2100 operating mode uses GE IS200EXHSG4A?G4 is the simplex-control, field-breaker version of the EXHS board.
-
Does GE IS200EXHSG4A include the 41T trip function?Yes. The G4 breaker-mode configuration uses both the 41T trip relay and the 41 close relay.
-
How does GE IS200EXHSG4A communicate with EMIO?Its command and conditioned-status circuits cable to EMIO through the EBKP backplane.
-
Which flashing devices are controlled by GE IS200EXHSG4A?The board provides pilot-relay control for the 53A and 53B field-flashing contactors.
-
What contact-sensing voltage is used by GE IS200EXHSG4A?The 41, 53A and 53B contact inputs are wetted by 70 V dc from redundant EX2100 supply paths.
-
Which feedback is conditioned by GE IS200EXHSG4A?It conditions field-breaker, flashing, crowbar and de-excitation status for the EX2100 control.
-
What must be isolated before replacing GE IS200EXHSG4A?Isolate the exciter field circuit, station-battery control supply, breaker coils and all stored-energy sources.
-
Which tests close a GE IS200EXHSG4A replacement?Verify exact identity, EBKP cabling, both 70 V dc paths, 41 close/41T trip action, 53A/53B sequence and EDEX status response.
