3. Key Advantages & Features
- Dual-Function Design: Combines 8 temperature inputs (TC/RTD) and 4 relay outputs in a single module, reducing cabinet space by 30% vs. separate I/O units.
- Precision Measurement: Factory-calibrated for ±0.1% accuracy (TC) with auto 冷端补偿，ensuring stable readings in fluctuating ambient conditions.
- Safety-Rated Outputs: Relay contacts rated for 5A (阻性负载), supporting direct actuation of valves, heaters, or alarms in SIL 2/3 systems.
- Hot-Swap Capability: Field-replaceable without system shutdown (GE-certified: < 15-minute replacement time).
- Diagnostic Depth: Real-time sensor fault detection (open/short circuit) with LED indicators for channel status.
4. Application Areas & Use Cases
Industries:
- Power Generation (steam turbines, boilers)
- Oil & Gas (refineries, pipeline heating)
- Manufacturing (plastic extrusion, metal casting)
Case Study:
A North American refinery adopted the IS200TPROH1C for furnace temperature control. The module’s integrated TC inputs and relay outputs reduced wiring complexity by 40%, while its 0.1% accuracy minimized overheating incidents. Result: 99.8% uptime over 12 months, saving $200,000 in unplanned downtime compared to legacy discrete I/O systems.

5. Competitor Comparison
Compared to similar temperature I/O modules:
- Integrated I/O Density: 8 inputs + 4 outputs in one module (vs. 6 inputs + 2 outputs in comparable models).
- Safety Ratings: SIL 3-compliant relay outputs (vs. SIL 2 in most 竞品).
- Calibration Flexibility: Onboard configurable filters (1–100 Hz) for noise suppression (no external signal conditioning required).

6. Selection Guidelines
- System Compatibility: Verify GE Mark V/VIe controller version (FW 4.0+ for Mark VIe).
- Sensor Type: Choose TC (wide temperature range) or RTD (high precision) based on application (e.g., RTD for -200°C to +600°C).
- Output Requirements: 4 relay channels suffice for basic control; upgrade to IS200TPROH2C (8 relays) for complex systems.
- Environment: Select conformal coating (optional) for corrosive environments (e.g., offshore platforms).
7. Installation & Maintenance Notes
-
Wiring: Use twisted-pair shielded cables for TC/RTD inputs (max length: 1,000 m for RTD 4-wire).
-
Relay Life: Rated for 100,000 operations (resistive); derate to 50,000 cycles for inductive loads.
-
Calibration: Annual verification recommended (GE’s Proficy software supports remote calibration).
-
ESD Protection: Ground module chassis to prevent electrostatic damage (ESD sensitivity: Class 2A).
