GE IS200EMCSG1AAB is a Conduction Sensor Board for Mark VIe systems, monitoring exciter conduction levels via sensor inputs, providing real-time data to the control system, featuring isolation, diagnostics, -40°C to +70°C operation, UL/CE compliance, ensuring safe and efficient exciter performance.
GE IS200EMCSG1AAB Conduction Sensor Board: Comprehensive Product Overview
The GE IS200EMCSG1AAB is a specialized Conduction Sensor Board engineered exclusively for GE’s
EX2100 excitation control system, serving as a critical monitoring and protection component for
silicon-controlled rectifiers (SCRs) in generator/motor excitation circuits. Its core function is to detect
and verify the conduction status of SCRs—key components that regulate DC excitation current—by
monitoring voltage drop across SCRs during operation, ensuring they switch on/off as intended to
prevent overcurrent, overheating, or excitation system instability. Unlike generic sensor boards, it
integrates dual-channel monitoring (supporting parallel SCR configurations common in high-power
excitation systems), real-time fault detection (e.g., SCR misfiring, open circuits), and direct
communication with the EX2100’s DSPX master controller via the EISB (Exciter Internal Serial Bus).
This enables instant alarm triggering and protective actions (such as de-excitation) if abnormal
conduction is detected, avoiding catastrophic damage to excitation windings or SCR modules.
Designed as a compact single-slot, 3U form factor module, it mounts seamlessly in EX2100 control
racks, with a ruggedized PCB coated to IPC-CC-830B standards to resist dust, moisture, and chemical
contaminants in industrial environments. The board features front-panel LED indicators (one per
monitoring channel) for at-a-glance status checks (green = normal conduction, red = fault),
simplifying on-site troubleshooting. It operates with a 24V DC backplane power supply and supports
a wide input voltage range (0–1000V DC) to accommodate varying SCR voltage drops in low- to high-
power excitation systems (from 500kVA backup generators to 1000MVA utility-scale generators).
Whether deployed in thermal power plants, steel mill motor excitation systems, or petrochemical
captive power facilities, the IS200EMCSG1AAB acts as a “safety sentinel” for SCR conduction,
ensuring reliable and safe operation of the entire excitation system.

FAQs
What is IS200EMCSG1AAB?
It is an Exciter Multibridge Conduction Sensor Card developed by GE under the Mark VI series.
What drives the RS-232C serial port?
The RS-232C serial port is driven by a computer chip known as a Universal Asynchronous Receiver/Transmitter (UART). This chip is responsible for sending data in the form of 8-bit bytes over the serial port. Each byte of data is preceded by a start bit, followed by 8 data bits, an optional parity bit, and one or two stop bits.
What is the significance of transmission baud rate?
The transmission baud rate indicates the speed at which bits are transmitted over the serial port, measured in bits per second. It determines how quickly data can be sent and received between devices.
What is the purpose of parity in serial communication?
Parity provides a mechanism to detect errors in the transmitted data. An additional parity bit is added to each byte of data to ensure that the total number of bits in the byte, including the parity bit, is either even or odd.
