GE IS200TREGH1BDB Turbine Speed Regulation Module

GE IS200TREGH1BDB | Turbine Speed Regulation Module

Product Overview

The GE IS200TREGH1BDB is a high-precision turbine speed regulation module designed for GE’s Mark VIe Speedtronic control system, a cornerstone of turbine automation in power generation, oil & gas, and heavy industry.

This module specializes in maintaining stable turbine speed and optimizing performance by processing feedback signals and adjusting control outputs—critical for grid synchronization and efficient energy conversion.

As a core component in turbine control loops, the IS200TREGH1BDB interfaces with speed sensors (e.g., magnetic pickups) and actuators (e.g., fuel valves) to regulate rotational speed within ±0.1% of setpoint.

It processes real-time data from these sensors, applying advanced PID algorithms to adjust fuel flow or steam intake, ensuring consistent operation even during load fluctuations.

What distinguishes the IS200TREGH1BDB is its triple-modular redundancy (TMR) design, with three independent processing channels that vote on output decisions.

This architecture eliminates single points of failure, making it ideal for mission-critical applications like nuclear power plants or offshore platforms.

Its hot-swappable capability allows replacement without system shutdowns, minimizing downtime in 24/7 operations. Compatible with GE’s Proficy Machine Edition, it simplifies calibration and diagnostics, enabling engineers to fine-tune parameters remotely.
