More Information

Overview Manuals Auxiliary Interfaces TMR Architecture Ground Detection Control Functions

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.

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.
Description
General Electric IS200EAUXH1A is an EX2100e Auxiliary Interface board that links the UCSx control sections to auxiliary excitation functions through High-speed Serial Link communication.

Contact and feedback paths converge on General Electric IS200EAUXH1A. The board handles 41DC contactors, 53A and 53B field-flashing relays, the 86G input, de-excitation and crowbar status, field-current and field-voltage feedback, bridge ac feedback and conditioned power-source monitor signals.

For field-ground detection, General Electric IS200EAUXH1A exchanges signals with the EXAM through a nine-conductor cable. The EXAM senses the voltage developed across the ground resistor, while the interface board processes the returned signal for leakage-current detection.

The H1 hardware group makes General Electric IS200EAUXH1A the TMR configuration serving M1, M2 and C. It can also accept the EAUD daughterboard when the 41DC path is changed from standard 125 V dc coil driving to the high-speed contactor interface.

Technical notes
General Electric IS200EAUXH1A is the H1 TMR auxiliary interface for EX2100e control sections M1, M2 and C.

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 a technician verify that IS200EAUXH1A matches the required redundancy architecture?
Confirm that IS200EAUXH1A is being placed in the H1 TMR arrangement serving M1, M2 and C; the H2 EAUX group is simplex.
Why might IS200EAUXH1A fail to report the 41DC, 53A or 53B contact states?
Check the 125 V dc wetting supply from the M1 and M2 power supplies because IS200EAUXH1A uses that source for all three contact inputs.
Which communication path should be checked when IS200EAUXH1A loses controller data?
The IS200EAUXH1A controller path uses HSSL through HSLA boards to the M1, M2 and C CSLA control sections.
How does IS200EAUXH1A participate in field-ground detection?
IS200EAUXH1A exchanges test and sensed signals with the EXAM through a nine-conductor cable to detect field-ground leakage current.
When is an EAUD daughterboard relevant to IS200EAUXH1A?
An EAUD daughterboard can be fitted to IS200EAUXH1A when the 41DC interface must change from standard 125 V dc coil driving to high-speed contactor operation.
What should be traced when de-excitation or crowbar status is missing at IS200EAUXH1A?
Verify the EDEX status-signal path into IS200EAUXH1A, where crowbar and de-excitation indications are conditioned before reaching the controllers.
