The GE IS200ERIOH1A (also designated IS200ERIOH1AAA) is an Exciter Regulator Main I/O Board designed for GE EX2100 generator excitation control systems. It acts as the primary signal gateway, interfacing system feedback signals, PT/CT inputs, and diagnostic channels with central regulator processing boards.
Technical Specifications
Operating Supply: 24 VDC logic power supply input
Signal Interface: Interfaces with EPCT (PT/CT board), ECTB (Contact board), and ERDD boards
Dimensions: 80 mm H x 186 mm W x 261 mm D
Weight: 1.14 kg
Status Indicators: Front panel POWER (Green), OK (Green), and ACTIVE (Green) LEDs
Operating Temperature: 0°C to +60°C (32°F to 140°F)
Key Features & Applications
The ERIO board supports both simplex and triple-redundant (M1, M2, C) excitation system configurations:
Versatile Signal Routing: Channels voltage transformer, current transformer, and contact status signals into excitation control loops.
Redundancy Management: The front panel ACTIVE LED provides real-time indication of master control status in redundant setups.
Test Equipment Ports: Includes test points designed for connecting oscilloscopes and chart recorders during commissioning.
Installation Guide
Rack Installation: Slide the board into its dedicated slot within the Exciter Regulator Backplane (ERBP).
Cable Fastening: Connect multi-pin ribbon cables from EPCT and ECTB terminal boards to the ERIO front connectors.
Ground Verification: Confirm backplane grounding chassis continuity prior to applying system power.
LED Diagnostic Check: Verify POWER and OK LEDs illuminate upon energizing the regulator rack.
Selection Tips
Configuration Verification: Select for either simplex backplane mounting or dual-mounting in redundant Exciter Regulator Redundant Backplanes (ERRB).
Firmware Synchronization: Ensure all I/O boards match system control software release levels.
Frequently Asked Questions (FAQ)
Q: What do the three LEDs on the front panel of IS200ERIOH1A represent? A: POWER indicates active DC input supply, OK confirms board diagnostic health, and ACTIVE indicates master status in redundant control modes.
Q: Is this board used for direct field customer wiring? A: No, customer field wiring connects to terminal boards (EPCT/ECTB), which then route signals into the ERIO board.
