GE IS200EISBH1AAB Exciter ISBus Board

GE IS200EISBH1AAB Exciter ISBus Board: Comprehensive Product Overview

The GE IS200EISBH1AAB is a specialized Exciter ISBus (EISB) Communication Board engineered as a 

critical data exchange hub within GE’s Speedtronic Mark VI turbine control system and EX2100 

excitation control ecosystem . Its core function is to serve as the "communication backbone" for 

excitation systems, enabling synchronized signal transmission between the M1 (Master 1), M2 (Master 

2), and C (Controller) units, while relaying high-speed feedback data to the DSPX master controller . 

Unlike generic communication boards, it integrates dual signal-handling capabilities: it processes 

fiber-optic feedback signals (e.g., generator field current/voltage from EDCF modules) and facilitates 

low-latency data exchange via GE’s proprietary ISBus interface—critical for maintaining excitation 

system stability in redundant configurations .

Designed as a compact single-slot, 3U form factor module, it mounts strategically in Mark VI VME 

card racks (13 or 21-slot configurations) beneath the DSPX controller for optimized connectivity . The 

front panel features six fiber-optic connectors to accept EMI-immune signals from generator fields 

and exciter components, plus a recessed reset switch for on-site troubleshooting . Internally, it 

integrates transformers, relays, and high-precision signal conditioning circuits to scale and process 4–

20 mA inputs (e.g., compressor stall detection, fuel pressure) and ±10V DC vibration signals, with 

hardware jumpers (J1/J2, J5/J6) enabling customization of output current ranges (20 mA or 200 mA) . 

Its rugged construction (conformal-coated PCB, -30°C to 65°C operating temperature range) ensures 

reliability in harsh industrial environments like power plants and steel mills, while compatibility with 

RS-232C tool/keypad interfaces simplifies on-site configuration and diagnostics .

Detailed Specification Table

Key Functional Features

Centralized Signal Routing: Eliminates complex point-to-point wiring by consolidating analog/digital signals from multiple exciter modules into a single interface. This simplifies installation, reduces wiring errors, and eases maintenance.

EMI & Transient Protection: Isolation circuits and EMI filters prevent interference from nearby high-voltage exciter cables or generator magnetic fields—ensures accurate signal transmission even in harsh industrial environments.

Fault Detection & Alarming: Monitors signal integrity (e.g., open wires, overcurrent) and triggers localized LEDs + Mark VI HMI alarms. Enables technicians to quickly identify issues (e.g., a broken analog wire vs. a module fault) without manual troubleshooting.

High-Speed Data Transmission: Fiber-optic ports support 100 Mbps data transfer to DSPX modules—ensures real-time synchronization of exciter status with the Mark VI control system (critical for fast shutdown responses to faults).

Industrial Durability:

Circuit boards feature conformal coating (per ISA-S71.04 G3) to resist moisture, dust, and corrosive gases (suitable for coastal or chemical plant environments).

Vibration resistance (0.15 mm peak-to-peak, 5–150 Hz) and shock resistance (15 g half-sine wave, 11 ms) – stable performance near rotating turbomachinery.
