Description
1. Product Title
GE IS200SPIDG1ABA – Mark VI / VIe Simplex Power Ionization Detector Interface Board
2. Product Overview
The IS200SPIDG1ABA is a specialized Simplex Power Ionization Detector (SPID) interface board manufactured by General Electric for the Speedtronic Mark VI and Mark VIe turbine control systems. This module is primarily used in combustion monitoring applications, specifically designed to interface with flame detection and ionization sensors. Its core function is to process high-sensitivity signals from the combustion chamber, providing the controller with critical data regarding the presence, intensity, and stability of the turbine flame.
In power generation, ensuring consistent combustion is vital for both operational efficiency and equipment safety. The IS200SPIDG1ABA solves the industrial challenge of accurately detecting flame-out conditions or combustion instability in real-time. By providing a ruggedized interface that can translate sensor data into actionable digital information, it enables the control system to execute emergency fuel shut-off or tuning sequences, preventing catastrophic “lean blowouts” or fuel accumulation hazards.

- Combustion Stability Analysis: Used to provide continuous feedback to the DLN (Dry Low NOx) control system to help maintain optimal emission levels and prevent acoustic oscillations.
- Safety Instrumented Systems (SIS): Acts as a critical input device for burner management systems (BMS), ensuring that fuel is only delivered when a valid ignition source or flame is present.
6. Frequently Asked Questions (FAQ)
- Q: What is the primary function of the IS200SPIDG1ABA ?
- A: It is an interface board that processes signals from flame and ionization detectors, allowing the GE Mark VI/VIe system to monitor the combustion process.
- Q: Does this board support redundant configurations?
- A: The IS200SPIDG1ABA is a “Simplex” (S) board. For applications requiring full TMR (Triple Modular Redundancy), a “TPID” (Triple Power Ionization Detector) board is typically used.
- Q: How does the “ABA” suffix affect the board’s usage?
- A: The “ABA” denotes the specific hardware revision. It is important to ensure this matches your system’s current configuration to guarantee compatibility with your specific I/O packs and firmware.
