GE IS200EISBH1A is an Exciter ISBus Board for Mark VIe systems, acting as a communication bridge between exciter control modules and the ISBus network. It enables stable data transmission, supports real-time control signal exchange, has isolation and diagnostics, operates at -40°C to +70°C, meets UL/CE, ensuring reliable exciter system communication.
GE IS200EISBH1A Exciter ISBus Board: Comprehensive Product Overview
The GE IS200EISBH1A is a mission-critical Exciter ISBus (EISB) Communication Board engineered as
the central data exchange hub of GE’s EX2100 excitation control system, responsible for seamless
signal transmission and controller coordination in generator/motor excitation systems. Its core role is
to act as a "neural switchboard"—receiving high-speed fiber-optic feedback signals (e.g., generator
field current/voltage from EDCF feedback boards) and relaying them to the DSPX master controller,
while enabling bidirectional communication between the DSPX, human-machine interface (HMI)
tools, and protective modules like ground detectors .
Designed as a compact single-slot, 3U form factor module, it mounts strategically in the control rack
beneath the DSPX controller for optimized connectivity . A key advantage is its support for GE’s
proprietary ISBus interface, which facilitates real-time data transfer among the system’s M1 (Master
1), M2 (Master 2), and C (Controller) units—critical for redundant excitation setups that demand zero
communication latency . It also integrates an RS-232C drive for tool/keypad communication (data
rates: 1200–38.4 KBaud) and front-panel fiber-optic connectors to accept signals from
generator/exciter fields, ensuring immunity to electromagnetic interference (EMI) in high-voltage
industrial environments . With no external LEDs or jumpers, it relies on system-level diagnostics to
monitor health, while its rugged construction (compatible with -20°C to 70°C operating temperatures)
ensures reliability in power plants, steel mills, and petrochemical facilities .

FAQs
What is the Exciter ISBus Board?
The Exciter ISBus Board (EISB) is a specialized communication board used with the M1, M2, and C controllers. It facilitates the reception and transmission of fiber-optic feedback signals and communicates between the DSPX controller and various ports using RS-232C.
What does the EISB board do?
The EISB board handles communication for exciter systems by receiving and transmitting fiber-optic feedback signals, sending data to the DSPX controller, and facilitating communication between the DSPX and tool/keypad ports. It also manages signals for redundant exciters and connects to the Ground Detection module.
Where is the EISB board located?
The EISB board is a single-slot, 3U-high module located in the control rack beneath the DSPX controller.
