The GE IS230TBTCH1C is a triple-modular redundant (TMR) thermocouple input assembly for the GE Mark VIe control system. This unit is a complete, pre-configured assembly designed to handle temperature inputs with a high degree of reliability and fault tolerance.
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 continuously compares the temperature readings from the three inputs, ensuring that the system can provide accurate data even if one or two modules fail. This redundancy is crucial for applications that require extremely high availability and safety.
- Thermocouple Input: The assembly is specifically designed to read low-level analog signals from thermocouples, which are common sensors used to measure temperature in industrial processes.
- Assembly: The part number signifies a complete, ready-to-install unit, including a terminal board for field wiring and the electronic I/O packs that process the signals.
- Mark VIe Integration: As part of the IS230 series, this assembly is designed to seamlessly integrate with the Mark VIe control platform, a system widely used for controlling turbines in power generation and other heavy industries.
Applications
The IS230TBTCH1C is used in industrial settings where the precise and reliable measurement of temperature is critical.
- Power Generation: It is a fundamental component in turbine control systems to monitor temperatures in critical areas like combustion chambers, bearings, and exhaust systems. The TMR configuration ensures that a temperature sensor or module failure won’t lead to a loss of control or an unnecessary turbine trip.
- Process Safety: This module is often used in safety-critical systems where an out-of-range temperature could indicate a dangerous condition, triggering an alarm or a safe shutdown.
