- Communication: RS-485 (MODBUS RTU) for bidirectional data exchange with Ovation controllers
- Alarm Functions: High/low temperature alerts, delta change alarms (user-configurable thresholds)
- Self-Diagnostics: Continuously monitors sensor faults (open circuit, short circuit) and module health (e.g., over-temperature, power failure)
- LED Indicators: Channel status (green = active, red = fault), power, communication
- Input Voltage: 24 VDC ±10% (supplied by Ovation system power supply, e.g., 5X00501G01)
- Power Consumption: ≤5 W (low power design for energy efficiency)
- Dimensions: 12.0 cm (W) × 7.7 cm (H) × 16.5 cm (D) (fits standard Ovation 3U rack slots)
- Weight: ~550 g (lightweight for easy installation)
- Mounting Type: Rack-mounted (front-panel latches for secure installation; hot-swappable)
- Enclosure Material: Anodized aluminum (corrosion-resistant, EMI-shielded)
- Operating Temperature: -40°C to +70°C (harsh industrial environments)
- Humidity: 5%–95% RH (non-condensing)
- Vibration/Shock Resistance: Compliant with IEC 60068-2-6 (5g, 10–500 Hz) and IEC 60068-2-27 (30g, 11 ms)
- Common Mode Rejection Ratio (CMRR): 120 dB (min) to reject noise from industrial environments
- Filtering: Built-in anti-aliasing filters (selectable 50/60 Hz) to ensure stable readings
- Dual Redundant Communication: Optional redundant RS-485 links to Ovation controllers for fault tolerance
- Module Redundancy: Configurable 1:1 redundancy with automatic failover (requires additional 5X00622G01 module)
- Software Tools: Configured via Emerson’s Ovation Engineering Workstation (OEWS) – graphical interface for channel setup, alarm thresholds, and calibration
- Firmware Updates: Field-upgradable via OEWS to add new features or enhance performance
The 5X00622G01 is widely used in industries requiring precise temperature monitoring:
- Power Generation: Turbine inlet temperature control, boiler feedwater temperature monitoring, condenser temperature optimization
- Oil & Gas: Refinery process heaters, pipeline temperature surveillance, offshore platform environmental monitoring
- Chemical & Petrochemical: Reactor temperature control, distillation column temperature profiling
- Water Treatment: Wastewater sludge digestion temperature management, cooling tower temperature regulation
- System Integration: Connects to Ovation controllers (e.g., 5X00481G01) via the Ovation Control Bus (OCB)
- Cabling: Shielded twisted-pair cables for RTD inputs (max length 1 km for 3-wire/4-wire configurations)
- Compatibility: Works with all Ovation I/O modules (e.g., 5X00119G01 analog input, 5X00167G01 analog output)
- Distributors: Authorized Emerson partners (e.g., Amikon, Saulelectric, Cambiaplc) – new and refurbished units available
- Warranty: 2 years (standard) for new units; 1 year for refurbished units
- Technical Support: Emerson provides 24/7 assistance via MyEmerson portal, including firmware updates and troubleshooting guides
- RTD Wiring: Use 3-wire or 4-wire configurations for accurate resistance measurement (minimize lead wire errors)
- Calibration: Factory-calibrated to NIST standards; field recalibration recommended every 2 years
- Documentation: For detailed wiring diagrams and pinouts, refer to Emerson’s Ovation 5X00622G01 RTD Input Module Technical Manual.
This module combines high accuracy, robust environmental protection, and seamless Ovation integration, making it ideal for mission-critical temperature control applications. Always follow Emerson’s installation guidelines and local safety codes during deployment.
