More Information

Overview Manuals Gate Firing Feedback & Monitoring Power & Indication Bridge Compatibility

Features:

  • Translates six UCSx commands into firing control for as many as six bridge SCRs.
  • Provides the H2 EBRG interface for thyristor systems of 77 mm or smaller.
  • Brings gate control, bridge feedback and operating indications onto one board.
Each EX2100e power conversion module uses one IS200EBRGH2A in its bridge-control path.

An EDIS-fed dc-to-dc converter develops the power required by the SCR gate circuits.

Visual indicators separate firing, current, supply, filter, airflow, temperature and fault information.

The General Electric IS200EBRGH2A Bridge Interface Board is supported by Apter Power with quotation and technical assistance.

SCR Command Path

  • Command Source: Six gate commands originate in the UCSx controller.
  • Controlled Devices: IS200EBRGH2A fires up to six SCRs on the power bridge.
  • Module Allocation: One bridge interface is installed for every PCM.
  • Board Role: All bridge-control signals pass through the EBRG hardware.

Bridge Condition Signals

  • Conduction State: The board receives current-conduction feedback from the bridge.
  • Current Sensing: Rogowski-coil feedback enters through the EBRG interface.
  • Analog Path: Bridge analog outputs are included in the signal set.
  • Operating Inputs: Airflow and bridge-temperature signals are monitored on the interface.

Supply and Status

  • Incoming Source: EDIS supplies nominal 125 V dc to IS200EBRGH2A.
  • Gate Supply: An on-board dc-to-dc converter powers the firing circuits.
  • Normal Indications: LEDs show output firing, bridge current and gate-power state.
  • Condition Indications: Separate lights identify filter, airflow, temperature, alarm and fault states.

H2 Converter Arrangement

  • Thyristor Class: H2 hardware is assigned to 77 mm or smaller devices.
  • SCR Range: The EBRG design supports multiple SCR ratings within its group boundary.
  • Converter Modes: EBRG hardware can serve simplex and warm-backup layouts.
  • Parallel Layout: Parallel bridge converter architecture is also supported.
Description
The H2 group identifies General Electric IS200EBRGH2A as an EX2100e Bridge Interface board for thyristor systems using 77 mm or smaller devices. It links the control hardware with the SCR power bridge and its related I/O terminal boards.

Six gate commands arrive at General Electric IS200EBRGH2A from the UCSx controller. The board applies those commands to the firing circuits for as many as six bridge SCRs, with one EBRG installed for each power conversion module.

Bridge control and operating feedback share General Electric IS200EBRGH2A. Its interfaces cover current conduction, Rogowski-coil current feedback, bridge analog outputs, airflow and temperature monitoring, placing firing control and bridge condition signals on the same hardware path.

A nominal 125 V dc source from EDIS feeds the on-board dc-to-dc converter of General Electric IS200EBRGH2A. Separate LED indications identify output firing, bridge current, gate-supply state, line-filter state, airflow, temperature and alarm or fault conditions.

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.
What bridge size must be matched before installing IS200EBRGH2A?
Use IS200EBRGH2A with the H2 EBRG arrangement specified for thyristor systems using 77 mm or smaller devices.
Why would an SCR bridge connected through IS200EBRGH2A receive no firing pulses?
Check the six command paths from the UCSx controller and the nominal 125 V dc supply from EDIS feeding IS200EBRGH2A.
How many IS200EBRGH2A boards belong in one power conversion module?
The EX2100e arrangement requires one IS200EBRGH2A bridge interface for each PCM, so the board count should follow the installed converter modules.
Which feedback routes help investigate an incorrect current indication around IS200EBRGH2A?
Trace both conduction feedback and the Rogowski-coil current path connected through IS200EBRGH2A before evaluating controller-side values.
What can the front indicators reveal when IS200EBRGH2A reports a bridge problem?
The LEDs on IS200EBRGH2A distinguish firing output, bridge current, gate power, line filter, airflow, temperature and alarm or fault states.
Can IS200EBRGH2A be used across different EX2100e bridge architectures?
IS200EBRGH2A supports the H2 thyristor range within simplex, warm-backup and parallel bridge converter arrangements described for EBRG hardware.
