Product Description

Overview

The GE IS200VTURH2BAB is a turbine-specific protection circuit board designed for the Mark VI Speedtronic control system. This VTUR module provides high-speed monitoring of shaft voltage, current, and rotational speed, while interfacing with overspeed solenoids and pulse-rate devices to ensure safe and efficient turbine operation. It is critical for precise turbine protection and control in gas and steam applications.

Technical Specifications

Performance Features

High-Speed Turbine I/O: Accepts signals from magnetic pickups (MPUs) and active speed probes for accurate shaft RPM monitoring. Critical for overspeed protection and governor control.

Flame Detection Integration: Interfaces with ultraviolet (UV) and infrared (IR) flame sensors, converting signals to discrete flame/no-flame logic for controller decision-making.

Generator Synchronization: Monitors generator voltage and frequency, enabling automatic turbine synchronization to the electrical grid.

Shaft Vibration Interface: Capable of processing specific seismic or proximity signals relevant for turbine startup and shutdown sequences.

Real-Time Processing: Low-latency signal handling ensures immediate response to safety-critical events such as sudden flame loss or overspeed conditions.

Robust Diagnostics: Built-In Test Equipment (BITE) continuously monitors internal power rails, pulse counters, and communication status to detect faults before they impact operations.

Noise Immunity & Thermal Design: Hardware filtering and heat-sink optimized layouts allow reliable operation in electrically noisy and thermally demanding turbine control environments.

Applications

• Overspeed Protection: Activates solenoids to safely shut down the turbine in over-speed events.

• Flame Monitoring: Ensures proper fuel combustion via UV/IR flame detection.

• Turbine Synchronization: Interfaces with generator systems for grid connection.

• Shaft & Rotor Monitoring: Supports precise RPM tracking and vibration sensing for turbine health.

FAQ

Q: What pulse rate range can the VTUR board process?
A: The board handles 2 Hz to 20 kHz with ±0.05% accuracy.

Q: Can this board operate in a redundant system?
A: Yes, it fully supports Simplex and Triple Modular Redundant (TMR) configurations.

Q: What sensors can be connected to this module?
A: Magnetic pickups, active speed probes, UV/IR flame detectors, and certain shaft vibration sensors.

Q: How should the board be configured when installed?
A: Pulse rate and voltage thresholds in the software must match the installed sensors to prevent false overspeed or loss-of-flame alarms.
