Product Description

Overview

The GE IS220PTURH1B (IS230TNTRH1C) is a dedicated Primary I/O Trip Pack for Mark VI and Mark VIe Speedtronic turbine control systems. Designed for gas and steam turbine protection, this module interfaces with field sensors through IS200TRPAS1A terminal boards, providing precise signal acquisition and control. It is compatible with both simplex and Triple Modular Redundant (TMR) configurations to maintain uninterrupted turbine safety operations.

Functional Highlights

• Primary Turbine Protection: Executes overspeed detection and emergency trip commands.

• High-Speed Signal Acquisition: Captures pulse inputs from magnetic pickups and proximity sensors for real-time turbine control.

• Redundant Architecture: Supports simplex, dual, or TMR setups to ensure continuous operation during maintenance or component failure.

• Integrated Communication: Dual 100 Mbps IONet Ethernet ports allow deterministic communication with Mark VIe controllers.

• Field Diagnostics: Onboard LEDs and IR diagnostic port facilitate local testing and troubleshooting.

• Environmental Resilience: Conformal-coated PCB and rugged chassis allow operation in -40°C to +70°C conditions.

Performance Characteristics

1. Precision Speed and Overspeed Monitoring

• Handles high-frequency pulses from MPUs and proximity sensors.

• Delivers speed readings across a wide dynamic range, from slow turning gear to high-speed turbine overspeed conditions.

• Accuracy within ±0.5% for precise governing and synchronization.

2. Comprehensive Turbine Signal Processing

• Supports shaft voltage/current monitoring to prevent bearing damage.

• Processes flame detection, potential transformer (PT), and breaker status inputs.

• Converts analog signals to digital data for the main controller in real-time.

3. Protection and Trip Logic

• Embedded independent hardware/software logic ensures rapid response to overspeed events.

• Interfaces with up to two turbine breakers for fast shutdown.

• Supports ±3 Hz slip range for stable speed control.

4. Communication and Maintenance

• Dual 100 Mbps full-duplex Ethernet ensures time-synchronized control communication.

• Hot-swappable in redundant setups, allowing replacement without system downtime.

• LED indicators for Power, Ethernet link, I/O health, and breaker status.
