Description
1. Product Description
The GE H201TIis a high-precision temperature input module designed by GE Fanuc, a globally recognized leader in industrial automation solutions. Part of the GE Fanuc PACSystems™ family, the H201TI specializes in converting thermocouple (TC) and RTD signals into digital data for PLC and distributed control systems (DCS). Its core functions include signal conditioning, linearization, and noise filtering, ensuring accurate temperature monitoring in critical industrial processes. With support for multiple temperature sensor types (e.g., J, K, T, R, S thermocouples; Pt100/Pt500 RTDs), the H201TI is ideal for industries such as manufacturing, energy, chemical processing, and food & beverage. Its robust design and modular compatibility make it a reliable choice for applications requiring precise temperature control.

3. Advantages and Features
- High Precision: Industry-leading accuracy (±0.1% for thermocouples) ensures reliable temperature measurements in extreme conditions.
- Flexible Configuration: User-configurable input types (TC/RTD) and cold-junction compensation (CJC) for thermocouples.
- Noise Immunity: Advanced filtering (50/60 Hz rejection) and galvanic isolation eliminate electrical noise interference.
- Modular Design: Easy integration with GE PACSystems I/O racks, supporting scalable system expansions.
- Diagnostic Capabilities: Onboard LED indicators for channel status and fault detection (e.g., open circuit, short circuit).
4. Application Areas and Use Cases
Industries: Chemical processing, oil & gas, power generation, pharmaceutical, and HVAC.
Use Case: A pharmaceutical plant deployed the GE H201TI to monitor temperatures in 50+ reactor vessels. The module’s 8-channel isolation and CJC reduced measurement errors by 90%, ensuring compliance with FDA regulations for batch processing. Downtime due to faulty temperature readings decreased by 75% post-installation.

6. Selection Recommendations
- Sensor Type: Match input type (TC/RTD) and sensor range (e.g., -200°C to +1800°C for thermocouples).
- Channel Requirements: Choose the H201TI (8 channels) for medium-scale systems; consider GE’s H202TI (16 channels) for larger setups.
- Environment: Ensure compatibility with ambient temperature (-40°C to +70°C) and humidity (5–95% non-condensing).
- System Integration: Verify compatibility with GE PACSystems controllers (e.g., RX3i, VMX) and Proficy® software.
7. Precautions
- Sensor Wiring: Use shielded cables for thermocouples to prevent EMI/RFI interference.
- Cold Junction Compensation: Enable CJC for thermocouple applications; ensure accurate ambient temperature reading at the module.
- RTD Wiring: Use 3-wire or 4-wire configurations to eliminate lead wire resistance errors.
- Power Supply: Maintain stable 24 VDC input; avoid voltage fluctuations > ±10%.
- Calibration: Perform periodic calibration (every 2 years) using certified reference standards.
