The GE IS200ERIOH1ACB is an Exciter Regulator I/O Board, a key component in GE’s Mark VI Speedtronic turbine control system and EX2100 excitation control system, supporting gas, steam, and wind turbine operations. As part of the Mark VI series—an upgrade over the Mark V with added wind turbine compatibility—it manages input/output (I/O) functions for the EX2100 Regulator Control, handling system and client I/O in both simplex and redundant configurations.
In simplex setups, it mounts in the ERBP slot, while redundant systems require three units across ERBP M1, ERRB M2, and C slots. Its dual-wide faceplate features a toggle switch, rear backplane connectors acquisition and storage. Static-sensitive, it requires careful handling, with its part number encoding details like domestic manufacture, “ERIO” functionality, Group 1 classification, conformal coating, and three revisions.
Features:
I/O Management: Handles system and client I/O for the EX2100 Regulator Control, critical for excitation system monitoring and control.
Redundancy Support: Adapts to simplex or redundant setups to ensure operational continuity.
Data Processing: FPGA and dual CPU sockets enable controlled data acquisition and storage, enhancing processing reliability.
Mark VI Integration: Compatible with the series’ Ethernet capabilities and wind/gas/steam turbine applications, upgrading Mark V functionality.
Durable Design: Conformal coating protects against environmental stress; rear connectors ensure secure backplane integration.
Part Coding: Part number reveals manufacture details, group classification, and revisions, aiding identification and maintenance.
