GE IS200PDOAH1B Turbine Protection Board

Product Introduction

The GE IS200PDOAH1B Turbine Protection Board is an advanced safety and control module engineered for GE Mark VI and Mark VIe turbine control systems. Designed to provide rapid and reliable shutdown commands, it monitors critical operating conditions—such as overspeed, vibration, and pressure—to protect turbines from damage during abnormal events. The board incorporates high-speed logic, redundant signal paths, and galvanic isolation to ensure dependable operation in demanding industrial environments, including gas, steam, and hydroelectric power generation.

Product Specifications

Applications

The IS200PDOAH1B Turbine Protection Board is widely deployed in:

• Gas and Steam Turbines – Ensuring rapid protective action during overspeed or pressure anomalies.

• Hydroelectric Generation – Safeguarding critical generator components from sudden load changes.

• Industrial Process Plants – Providing emergency trip control in refineries, petrochemical facilities, and power stations.

• Retrofit Projects – Modernizing legacy systems to meet contemporary safety and reliability standards.

Advantages

• Fast Response – High-speed logic enables turbine trip commands in under 10 ms.

• Robust Isolation – 2500 V RMS isolation protects control electronics from high-voltage transients.

• Redundant Architecture – Dual-signal paths and hot-swap capability enhance system availability.

• Comprehensive Diagnostics – Continuous self-tests and LED indicators simplify maintenance and fault detection.

• Flexible Integration – Seamless compatibility with GE Mark VI/VIe systems for new installations or upgrades.

• Low Power Draw – Efficient design reduces energy consumption and heat buildup.

FAQ

1. What is the main protective role of the IS200PDOAH1B?
   It detects critical turbine conditions—such as overspeed or severe vibration—and issues immediate trip signals to shut down the turbine safely.

2. How quickly can it respond to a trip condition?
   The board provides a typical fault-to-trip response time of less than 10 milliseconds, ensuring rapid shutdown.

3. What kind of input signals are supported?
   It supports both digital and analog protection inputs, including speed probes, pressure switches, and vibration transducers.

4. Is galvanic isolation provided?
   Yes, the board offers 2500 V RMS galvanic isolation between input, logic, and output circuits to prevent ground loops and surges.

5. Can it be hot-swapped during operation?
   Yes, the design supports hot-swapping, allowing maintenance or replacement without shutting down the turbine control system.

6. How are fault conditions indicated?
   Front-edge LED indicators display power status, communication activity, and fault states for quick on-site diagnostics.

7. Does it support redundant configurations?
   Yes, it can be deployed in dual redundant architectures to maintain protection even if one board fails.

8. What communication protocol is used for system integration?
   The board communicates via the Mark VI/VIe high-speed proprietary control bus for real-time data exchange.

9. How are trip outputs protected against short circuits?
   Each output channel includes electronic current limiting and thermal shutdown features to protect against short-circuit faults.

10. What is the maximum cable length for input sensors?
    The board supports shielded twisted-pair cabling up to 100 meters for most sensor types without signal degradation.
