Features:
- Routes EX2100e auxiliary functions to TMR control sections over HSSL.
- Combines contactor, field-feedback and bridge-ac signal interfaces on one board.
- Supports field-ground detection through the connected EXAM module.
The H1 configuration gives IS200EAUXH1A three control paths for M1, M2 and C.
Three contact inputs receive 125 V dc wetting power from the redundant control supplies.
An optional EAUD daughterboard changes the 41DC output path for high-speed contactor service.
Apter Power lists the General Electric IS200EAUXH1A Exciter Auxiliary Interface Board for quotation and technical support.

Signal Connections
- Controller Link: HSSL carries data between IS200EAUXH1A and the UCSx control sections.
- Main Contactor: The board provides the interface for the 41DC contactor circuit.
- Field Flashing: Interfaces are provided for the 53A and 53B relays.
- Lockout Input: The 86G contact input is handled on the auxiliary interface.
Redundant Control Layout
- Hardware Group: H1 identifies the triple modular redundant EAUX arrangement.
- Control Sections: M1, M2 and C each connect through the HSLA and CSLA path.
- Input Power: Contact wetting is supplied from both M1 and M2 power supplies.
- Optional Driver: The EAUD daughterboard is accepted by the H1 auxiliary interface.
EXAM Signal Path
- Paired Module: IS200EAUXH1A works with the EXAM to support field-ground detection.
- Cable Route: A nine-conductor cable transfers the ground-detector signals.
- Sensing Point: EXAM measures voltage developed across its ground resistor.
- Processed Result: The returned signal is used to detect field-ground leakage current.
Conditioning and Feedback
- Status Processing: Crowbar and de-excitation indications from EDEX are conditioned on the board.
- Field Signals: Current and voltage feedback paths enter the auxiliary interface.
- Bridge Input: Bridge ac feedback is routed through the EAUX circuitry.
- Source Monitoring: Signals from power-source monitors are conditioned before control processing.
