GE IS200ERIOH1A Exciter Regulator I/O Board Mark VI

Product Overview

The GE IS200ERIOH1A is an Exciter Regulator I/O board for the EX2100 system and Mark VI series. It provides system and customer I/O for both simplex and redundant regulator control applications. The board features a double‑wide faceplate with toggle switch, two backplane connectors (P1/P2), dual CPU sockets, and an FPGA for data acquisition into DPM. Weight: 0.45 kg.

Core Advantages

Flexible Redundancy Support

Supports simplex (single board in ERBP) and redundant (three boards in ERRB M1/M2/C) configurations. Adapts to your system's availability requirements.

Comprehensive I/O Interface

Interfaces with ECTBG2/EPCT terminal boards for customer I/O, and EROC/ERDD for system I/O. In redundant systems, also interfaces with ERRR relay board.

FPGA Data Management

Field‑Programmable Gate Array controls data acquisition and storage into Dual Port Memory (DPM) for fast, deterministic I/O handling.

Specifications

Installation Tips

Simplex Configuration

Mount the IS200ERIOH1A in the ERBP backplane. It interfaces customer I/O via ECTBG2 and EPCT terminal boards through two 25‑pin connectors.

Redundant Configuration

Install three boards in ERRB backplane at M1, M2, and C positions. All three controllers share the same PCB for coordinated redundant operation.

FPGA & DPM

The FPGA handles data acquisition and storage into DPM. Ensure firmware is compatible with your EX2100 system version.

Why Choose IS200ERIOH1A?

Delivers versatile I/O interfacing for GE EX2100 excitation systems. Supports both simplex and triple‑redundant configurations. The FPGA‑based data acquisition ensures fast, deterministic I/O handling. Double‑wide faceplate with toggle switch provides easy manual control. Built to GE's Mark VI quality standards, this board is essential for turbine excitation regulation.

FAQs

Q1: What does the "A" revision indicate?
A1: The "A" denotes a later revision of the original part, typically including enhancements or component updates.

Q2: How many boards are needed for redundant systems?
A2: Three boards are required, mounted at ERRB positions M1, M2, and C for full TMR redundancy.

Q3: What does the toggle switch on the faceplate do?
A3: The toggle switch provides manual control access. Its specific function depends on system configuration — refer to your EX2100 manual.
