GE IS220PRTDH1BC 336A5026ADP13

Description

Product Description

The GE IS220PRTDH1BC 336A5026ADP13 is a specialized I/O module for the GE Mark VI and Mark VIe Speedtronic gas/steam turbine control system. This module is a RTD (Resistance Temperature Detector) Input Module, designed to interface directly with multiple RTD temperature sensors used for critical machinery monitoring. The IS220PRTDH1BC conditions, digitizes, and transmits precise temperature readings from RTDs measuring parameters like bearing temperature, metal temperature, and winding temperature to the turbine controller. The suffix 336A5026ADP13 denotes a specific assembly or revision. Integrating the GE IS220PRTDH1BC module is essential for reliable and accurate thermal protection and monitoring of turbines and associated equipment.

Product Parameters and Specifications

• Product Type: RTD Input Module for Mark VI/VIe.
• Compatible Systems: GE Mark VI, Mark VIe, Mark VIeS Turbine Control Systems.
• Sensor Input: Accepts signals from multiple RTD sensors, most commonly Pt100 (100 ohm at 0°C) RTDs in a 2-wire, 3-wire, or 4-wire configuration. The module is specifically configured for one of these wiring types.
• Input Channels: Typically 8 or 16 channels per module, allowing dense temperature monitoring from one physical location.
• Excitation: Provides a precise, low-noise constant current source to excite the RTD.
• Measurement: Performs ratiometric measurement to eliminate errors from lead wire resistance (especially in 3-wire and 4-wire configurations).
• Accuracy: High accuracy and resolution suitable for critical protection and control, often within ±0.5°C or better.
• Diagnostics: Includes comprehensive diagnostics for sensor faults such as open circuit, short circuit, and out-of-range signals.
• Communication: Connects to the turbine controller via the Mark VIe backplane (VME) or network.

Advantages and Features

1. High-Density, Precision Temperature Measurement: The GE IS220PRTDH1BC 336A5026ADP13 provides a high channel count for RTDs in a single slot, enabling centralized and accurate monitoring of numerous temperature points on a turbine-generator set, which is critical for thermal protection and efficiency.
2. Advanced Lead-Wire Compensation: By supporting 3-wire and 4-wire RTD connections, the module automatically compensates for the resistance of the lead wires, ensuring the temperature reading reflects only the sensor’s resistance at the measurement point. This is a critical feature for accuracy over long cable runs.
3. Integrated Sensor Diagnostics: The module continuously monitors the health of each connected RTD circuit. It can detect open wires, shorted sensors, or drifted values, providing early warnings to operators and maintenance personnel before a sensor failure leads to a false trip or loss of protection.
4. Seamless Integration with Turbine Control Logic: As a native Mark VIe component, its data is directly available to the turbine control application (ToolboxST). Temperature points can be directly used in protection algorithms (e.g., high-temperature trips), control loops, and historical data collection without external signal conversion.
5. Robust Industrial Design: Built to the demanding specifications of turbine control environments, with high immunity to electromagnetic interference (EMI) and vibration, ensuring reliable operation adjacent to high-power equipment.

Application Cases in Various Fields

• Gas & Steam Turbine Protection: Monitors critical temperatures such as turbine bearing metal temperatures, generator stator winding temperatures, and exhaust gas temperatures for protection against overheating and for condition-based maintenance.
• Compressor Stations: Measures bearing and discharge temperatures on centrifugal and axial compressors in pipeline and process applications to prevent mechanical failure.
• Large Motor and Pump Monitoring: Used for winding and bearing temperature monitoring on critical high-voltage motors and large pumps (e.g., boiler feed pumps) driven by turbines.
• Power Generation Auxiliaries: Monitors temperatures in heat recovery steam generators (HRSGs), lube oil coolers, and other balance-of-plant equipment.

Comparison with Competing Products

• vs. Individual Temperature Transmitters: Using individual 4-20 mA transmitters for each RTD is more expensive, requires more wiring and panel space, and lacks the centralized diagnostics and configuration of the multi-channel IS220PRTDH1BC module.
• vs. Universal Analog Input Cards: A universal card set for voltage/current would require external signal conditioning for RTDs and would not provide built-in lead-wire compensation or dedicated RTD diagnostics. The dedicated GE module is optimized for this specific sensor type.
• vs. Other Turbine Control RTD Modules (e.g., Woodward): Competing turbine OEMs have similar modules. The IS220PRTDH1BC is distinguished by its native integration with the GE Mark VIe system, its configuration within ToolboxST, and its use of GE’s specific application libraries for turbine protection.

Selection Suggestions and Precautions

1. Verify RTD Type and Wiring Configuration: This is the most critical step. The IS220PRTDH1BC module must be ordered and configured for the specific RTD type (Pt100) and the wiring method (2-, 3-, or 4-wire). Mismatched configuration will cause significant measurement errors.
2. Use High-Quality RTDs and Wiring: For accurate measurements, use industrial-grade, 3-wire or 4-wire RTDs with the correct temperature range. Use dedicated, shielded twisted-pair cable for each sensor and follow proper grounding practices.
3. Correct Configuration in ToolboxST: Each channel must be correctly configured in the ToolboxST hardware configuration for its sensor type, engineering units, alarm setpoints, and diagnostic limits. The module’s firmware revision must be compatible with the controller software.
4. Sensor and Loop Testing: During commissioning, verify each RTD loop by measuring its resistance with a precision ohmmeter at a known temperature and comparing it to the value read by the Mark VIe controller through the 336A5026ADP13 module.
5. Obsolescence and Documentation: This is a system-specific module. Ensure you have the correct hardware manual and that the module’s assembly number (336A5026ADP13) matches your system’s spare parts list. Sourcing exact replacements can be complex.
