The 5X00119G01 is widely used in industries requiring high-accuracy temperature control:
- Power Generation: Monitoring turbine inlet temperatures, boiler water temperatures, and generator stator winding temperatures.
- Process Industries: Chemical reactors, petrochemical distillation columns, and pharmaceutical batch processes.
- HVAC Systems: Precision climate control in data centers, cleanrooms, and industrial facilities.
- Oil & Gas: Pipeline temperature monitoring, refinery heat exchangers, and offshore platforms.
- Ovation System Integration:
- Works with Ovation controllers (e.g., 5X00247G01) and I/O racks.
- Requires a personality module (e.g., 5X00121G01) for configuration and communication with the DCS network.
- Wiring:
- RTD inputs: Screw terminals for 2/3/4-wire connections.
- Power: Separate terminal block for 12/24 VDC supply.

- Warranty: 2 years (standard) for new units; 1 year for refurbished units.
- Documentation: Emerson’s Ovation 5X00119G01 RTD Input Module Datasheet provides detailed pinouts, wiring diagrams, and calibration procedures.
- Redundancy: For critical applications, pair with redundant Ovation I/O racks and power supplies to eliminate single points of failure.
- Calibration: Factory-calibrated for PT100 sensors; field recalibration can be performed via OEWS if needed.
- Derating: Output current may need derating at altitudes above 2000 meters or temperatures exceeding 60°C.
This module combines high precision, robust design, and seamless Ovation DCS integration, making it ideal for mission-critical temperature monitoring and control. Always follow Emerson’s installation guidelines and local electrical codes during setup.
