System Role & Functional Behavior
The IS200TRTDH1CCC acts as the temperature sensing front-end interface in GE turbine control systems:
- Collects resistance signals from multiple RTD sensors
- Supports three-wire RTD configurations for improved accuracy
- Converts resistance changes into measurable voltage signals
- Applies noise suppression and fault detection at the hardware level
- Sends processed signals to VRTD/VAIC control modules
This ensures stable thermal monitoring even in high-noise industrial environments such as turbine housings and power plant enclosures.
