Features:
- Redundant and Simplex Control Compatibility – Supports both ECTBG1 (redundant) and ECTBG2 (simplex) for flexible EX2100™ integration.
- Robust Relay Output Management – Provides 2 trip outputs and 4 general-purpose Form-C contacts for reliable excitation and lockout control.
- Comprehensive Input Monitoring – Handles auxiliary contacts and 52G/86G inputs powered at 70 V DC, ensuring full system feedback.
The General Electric IS200ECTBG2ADE is engineered for industrial power generation and excitation control, supporting EX2100™ Excitation Control systems with precise relay outputs and monitored inputs. Its two board versions, ECTBG1 and ECTBG2, allow operators to select configurations suitable for either redundant or simplex control systems, providing reliability and flexibility in installation.
Power management is a key strength of the IS200ECTBG2ADE. Trip relays are powered from M1 in simplex mode and from both M1 and M2 controllers in redundant setups. This ensures critical excitation functions continue even in the event of a single controller failure. Each relay output driving a customer lockout uses dual normally-closed contacts, guaranteeing fail-safe operation and minimizing risk during maintenance or system faults.
Installation and integration of the IS200ECTBG2ADE are simplified by its compact terminal layout and compliance with UL and CSA standards. The board supports external suppression for relay protection, while its comprehensive input monitoring, including 70 V DC auxiliary contacts and 52G/86G inputs, enables seamless interface with field devices. This combination of features strengthens operational safety and maximizes uptime for industrial power systems.
The IS200ECTBG2ADE General Electric Exciter Contact Terminal Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Temperature Range: Ambient operating temperature -30℃ to +65℃ (-22°F to 149°F).
- Humidity Requirements: 5% to 95% relative humidity, non-condensing.
- Power Input: Rated operating voltage 125 V dc (provided by the system backplane or external excitation power supply).
- Interference Immunity: Must be installed in a control cabinet with good electromagnetic compatibility (EMC) protection to resist high-frequency interference from the generator set.
- Contact Wetting Power: Provides 70 V dc voltage for monitoring external auxiliary contact inputs, ensuring reliable signal transmission.
- Trip Outputs: Includes 2 dedicated trip contacts for connecting to the customer's lockout circuit for emergency shutdown protection.
- General Purpose Relays (GP Relays): Configured with 4 Form-C (on/off selectable) general purpose relays for status feedback (e.g., excitation operation, fault alarm, etc.).
- Signal Isolation: All input and output signals are opto- or physically isolated to prevent high voltage from entering the core control system.
- Simplplex Excitation Control: The "G2" at the end of this model indicates that it is specifically designed for non-redundant systems, suitable for small and medium-sized power plants or standby generator sets.
- Circuit Breaker Status Monitoring: Used to monitor the auxiliary status of the generator circuit breaker (GCB) or excitation switch.
- External Fault Interlocking: Receives trip commands from external protection devices such as transformer heavy gas protection and differential protection.
- DCS System Integration: Through its relay outputs, it uploads key operating statuses of the excitation system (e.g., "excitation closing") to the central control room DCS.
