The GE IS230TNRTH3D is a triple-modular redundant (TMR) RTD input module assembly for the GE Mark VIe control system. The part number indicates it’s a complete, ready-to-install unit, including a TRTDH1D terminal board and two PRTDH1B I/O packs. It’s designed for high-reliability temperature monitoring using RTD sensors.
Key Features
- TMR (Triple-Modular Redundant): This is the most critical feature. The TMR configuration uses three identical I/O packs operating in parallel. A voting algorithm compares the temperature readings from all three packs, ensuring the control system receives the correct information even if one or two modules fail. This redundancy is crucial for preventing a turbine trip or other critical event due to a single component failure.
- RTD Input: The module is specifically designed to handle inputs from Resistance Temperature Detectors (RTDs). RTDs are highly accurate temperature sensors that work by measuring changes in electrical resistance. The module accurately converts this resistance change into a temperature reading.
- Assembly: The part number signifies a complete unit, consisting of both the terminal board (TRTDH1D) where the RTD wiring is terminated and the two electronic I/O packs (PRTDH1B) that process the signals.
- Mark VIe Integration: As part of the IS230 series, this assembly is a key component of the Mark VIe control platform, widely used for controlling turbines in power generation and other heavy industries.
Applications
The IS230TNRTH3D is used in mission-critical industrial settings where the accurate and continuous monitoring of temperature is essential for safe operation.
- Power Generation: It is a core component in a turbine’s control and protection system, providing a reliable input for trip logic that shuts down the unit in a controlled manner if an over-temperature condition is detected in a bearing, exhaust, or other critical component.
- Safety Systems: The TMR configuration makes it integral to safety-instrumented systems, where a failure to monitor a temperature signal could result in equipment damage or a safety risk.
- Oil and Gas: In refineries and offshore platforms, it monitors the temperature of critical equipment like pumps, compressors, and reactors to ensure they operate within safe limits.
