GE IS200ECTBG1ADE Product Specification
Product Overview
The GE IS200ECTBG1ADE is a high-reliability Exciter Contact Terminal Board engineered for GE’s Mark VI Turbine Control System, a cornerstone of industrial automation in power generation, oil and gas, and heavy machinery sectors. Designed to manage critical exciter contact functions in redundant control architectures, this module serves as a vital interface between turbine speed control systems and auxiliary equipment, ensuring seamless coordination of power generation processes. As part of the Mark VI series, the GE IS200ECTBG1ADE leverages GE’s decades of expertise in rotating equipment control, delivering precision, durability, and compatibility with legacy and modern automation platforms.
Constructed with dual power inputs (M1/M2) and six auxiliary contact terminals, the GE IS200ECTBG1ADE provides fail-safe operation in demanding environments. Its four form-C relay outputs, controlled by the adjacent EMIO board, enable precise switching of external devices such as circuit breakers, solenoids, or alarms. The module’s rugged design includes a thick conformal coating on critical components, protecting against dust, moisture, and electromagnetic interference (EMI), while its compact form factor (200 mm × 150 mm × 50 mm) and lightweight (1.2 kg) facilitate easy integration into 19″ control racks.
In automation systems, the GE IS200ECTBG1ADE acts as a frontline component in turbine protection schemes, ensuring rapid response to speed fluctuations or operational anomalies. Its backward compatibility with the first two revisions of the Mark VI series allows seamless upgrades in existing installations, reducing downtime and retrofit costs. By combining advanced relay technology with robust hardware, the module enhances system reliability, minimizes maintenance interventions, and supports continuous operation in mission-critical applications like steam turbine generators and gas compressor trains.

Main Features and Advantages
Redundant Power and Signal Paths: The GE IS200ECTBG1ADE features dual power inputs (M1/M2) and independent relay outputs, ensuring continuous operation even if one power source fails. This redundancy is critical in applications where downtime translates to significant operational losses, such as in power plant turbine control systems.
Flexible Relay Configuration: With four form-C relays and six auxiliary contacts, the module supports diverse switching requirements, from controlling generator field breakers to interfacing with external safety systems. The relays are rated for high switching currents (up to 5 A), making them suitable for both low-voltage logic signals and medium-power loads.
Rugged Industrial Design: The conformal coating on key components protects against harsh environmental factors, including oil mist, salt spray, and extreme temperature fluctuations. This durability ensures a long service life in offshore platforms, refineries, and other industrial settings with aggressive operating conditions.
Backward Compatibility: Designed to work with the first two revisions of the Mark VI series, the GE IS200ECTBG1ADE allows easy retrofitting into legacy systems without hardware modifications. This feature minimizes upgrade costs and simplifies inventory management for plants using mixed generations of GE control equipment.
Efficient Heat Dissipation: The module’s compact yet ventilated design ensures optimal heat dissipation, preventing thermal stress-induced failures during prolonged high-load operation. This thermal stability is essential for maintaining signal integrity in high-temperature environments like gas turbine enclosures.

Installation and Maintenance
Pre-installation Preparation:
Before installing the GE IS200ECTBG1ADE, ensure the following:
Before installing the GE IS200ECTBG1ADE, ensure the following:
- Verify the power supply meets 24 VDC ±10% and that the control rack is properly grounded to prevent electrostatic discharge (ESD). Use a multimeter to check voltage stability and continuity.
- Clean the mounting area to remove dust and debris, and ensure the rack has sufficient space (at least 50 mm clearance) for airflow around the module.
- Use anti-static gloves and packaging during handling to protect sensitive circuitry. Secure the module in the rack using the provided DIN rail or screw mounts, tightening fasteners to 0.5–1.0 Nm torque to avoid damage.
Maintenance Recommendations:
- Routine Inspections: Monthly visual checks of front-panel LEDs (green for normal operation, red for faults) and relay contacts for signs of arcing or wear. Clean the module’s ventilation slots with a soft brush to maintain airflow efficiency.
- Functional Testing: Quarterly verification of relay operation using a test light or multimeter to confirm proper switching. Simulate fault conditions (e.g., loss of M1 power) to ensure redundancy mechanisms activate correctly.
- Coating Integrity: Annually inspect the conformal coating for cracks or delamination, especially in high-humidity environments. Repair or reapply coating as needed to maintain EMI and corrosion protection.
- Firmware Updates: Periodically update the firmware of adjacent EMIO boards (if applicable) to ensure compatibility with the GE IS200ECTBG1ADE, particularly when integrating with newer Mark VI system revisions.
