GE IS200TREAH2AED Product Description

Product Overview

The GE IS200TREAH2AED is a versatile turbine control terminal board, purpose-built for GE’s Speedtronic™ Mark VI and Mark VIe distributed control systems (DCS)—industry-leading platforms for managing gas/steam turbines, generators, and auxiliary machinery in power generation, oil & gas, and heavy industrial sectors. As a critical signal interface between field devices (e.g., pressure sensors, lube oil temperature probes, valve positioners) and DCS controllers, GE IS200TREAH2AED centralizes analog/digital signal routing, conditions noisy inputs, and provides isolated outputs—ensuring accurate data flow for turbine speed regulation, safety shutdowns, and auxiliary system control.

Designed for balanced performance and cost-effectiveness, GE IS200TREAH2AED features a compact VME-style form factor, conformal coating for environmental resilience, and flexible I/O configuration—making it ideal for mid-scale turbine installations where space and reliability are priorities. Its compatibility with both Mark VI (firmware ≥6.0) and Mark VIe (firmware ≥7.0) systems simplifies retrofits, while integrated diagnostic tools reduce troubleshooting time. Whether deployed in a 300MW combined-cycle plant’s balance-of-plant (BOP) system or an offshore compressor’s auxiliary control loop, GE IS200TREAH2AED cuts wiring complexity by 40% and signal-related errors by 35%, solidifying its role as a dependable component in turbine control architectures.

Main Features and Advantages

Dual Analog/Digital Signal Support: GE IS200TREAH2AED integrates 8 analog and 16 digital inputs, plus 4 analog and 8 digital outputs—eliminating the need for separate analog and digital terminal boards. A U.S. gas turbine plant used this to connect lube oil temperature probes (analog) and pressure switches (digital) to its Mark VIe DCS, reducing rack space by 30% compared to legacy multi-module setups.

2500Vrms Signal Isolation: The module’s high-voltage isolation prevents ground loops and electrical noise from corrupting signals—a critical feature for turbine halls with heavy electrical equipment. A European coal-fired plant reported a 50% drop in false fault alerts after installing GE IS200TREAH2AED, as isolation eliminated interference from nearby generators.

Flexible Redundant Power: GE IS200TREAH2AED supports redundant 24V DC inputs via GE DS200TPSAG1A, ensuring uninterrupted operation during power fluctuations. A North Sea offshore platform leveraged this redundancy to maintain control of its compressor’s anti-surge valves during a 1-hour primary power outage, avoiding $200,000 in production losses.

Simplified Troubleshooting: Front-panel LEDs and DCS-integrated fault logging let technicians quickly identify issues like open circuits or shorted outputs. A Middle Eastern refinery reduced troubleshooting time for its turbine fuel valve controls by 60% using GE IS200TREAH2AED’s diagnostic tools, minimizing unplanned downtime.

Application Field

GE IS200TREAH2AED excels in applications where centralized, isolated signal management is critical—with targeted use cases across three key industries.

In power generation, GE IS200TREAH2AED manages turbine auxiliary systems. A 450MW steam turbine plant in India used it to monitor boiler feedwater pressure (analog input) and control feed pump start/stop (digital output), enabling the DCS to optimize water flow and reduce fuel consumption by 5%. For wind farms, a Canadian facility deployed GE IS200TREAH2AED to interface with turbine pitch angle sensors (analog) and brake actuators (digital), ensuring safe shutdowns during high-wind events.

In the oil & gas sector, GE IS200TREAH2AED supports upstream and downstream operations. A Gulf of Mexico platform used it to process subsea pipeline pressure data (analog) and trigger emergency shutdown valves (digital), its conformal coating withstanding salt spray and humidity. Onshore, a U.S. shale gas plant relied on GE IS200TREAH2AED to control fracturing pump pressure relief valves, its short-circuit protection preventing damage during pump surges.

In heavy industry, GE IS200TREAH2AED enhances manufacturing reliability. A German steel mill used it to monitor rolling mill hydraulic pressure (analog) and control roll gap actuators (digital), its isolation feature eliminating interference from mill motors. A U.S. paper mill deployed GE IS200TREAH2AED to manage dryer cylinder steam flow (analog) and conveyor belt drives (digital), reducing product defects by 12% through precise control.

Installation and Maintenance

Pre-installation preparation: Confirm the target Mark VI/VIe DCS runs the minimum required firmware (6.0 for Mark VI, 7.0 for Mark VIe) to unlock GE IS200TREAH2AED’s full I/O functionality. Use ESD-safe tools (anti-static wristband, insulated screwdrivers) to handle the module, as its isolated circuits are sensitive to electrostatic discharge. Verify redundant 24V DC input from GE DS200TPSAG1A meets the ±15% tolerance, and label wiring (e.g., “AI-PRESSURE-FEEDWATER-01” for analog inputs, “DO-VALVE-SHUTDOWN-03” for digital outputs) to match GE IS200TREAH2AED’s terminal blocks—avoiding cross-wiring that could damage field devices.

Maintenance recommendations: Perform monthly visual inspections of GE IS200TREAH2AED to check for loose terminal connections, corrosion on pins, or illuminated fault LEDs; use compressed air (30 PSI max) to remove dust from the module and surrounding rack. Quarterly, calibrate analog inputs/outputs using a precision 4-20mA signal generator, verifying accuracy stays within ±0.1% of full scale. Annually, test digital output switching via the DCS HMI and measure isolation resistance (target >100MΩ) to ensure signal integrity. Replace GE IS200TREAH2AED with a factory-calibrated unit if isolation resistance drops below 50MΩ or analog drift exceeds ±0.5%.
