Advantages & Features

1. Specialized RTD Measurement: HONEYWELL 05701-A-0325 is optimized for RTD sensors, supporting 2/3/4-wire configurations to eliminate lead wire resistance errors—critical for high-precision temperature monitoring (e.g., boiler tube temperature measurement).
2. High Accuracy & Stability: 16-bit resolution and ±0.2°C accuracy (0-600°C) ensure reliable temperature data, while built-in self-calibration maintains performance over time without frequent manual adjustments.
3. Comprehensive Diagnostics: Open RTD detection, short circuit alerts, and lead wire compensation failure monitoring enable proactive maintenance, preventing process disruptions caused by faulty sensors or wiring issues.
4. Wide Compatibility & Hot-Swap Support: The module integrates with Honeywell’s control systems and third-party platforms via Modbus, and hot-swappable installation allows replacement without system shutdown—reducing maintenance downtime.

Application Fields & Cases

1. Power Plant Boiler Temperature Monitoring: A coal-fired power plant deployed HONEYWELL 05701-A-0325 modules to measure boiler tube temperatures (4-wire Pt100 RTDs) in its steam generation system. The module’s lead wire compensation eliminated measurement errors, enabling early detection of overheating and preventing tube failures.
2. Chemical Plant Reactor Temperature Control: A petrochemical plant integrated HONEYWELL 05701-A-0325 into its Experion PKS system to monitor reactor jacket temperatures (3-wire Pt100 RTDs) during batch production. The module’s high accuracy enabled precise control of cooling water flow, ensuring consistent product quality and reducing waste.
3. Food Processing Freezer Monitoring: A frozen food manufacturer used HONEYWELL 05701-A-0325 to measure freezer temperatures (2-wire Pt1000 RTDs) in its cold storage facilities. The module’s wide operating temperature range (-40°C to +70°C) and diagnostic capabilities ensured reliable monitoring in extreme cold environments.

Selection Suggestions & Precautions

1. Selection Suggestions: HONEYWELL 05701-A-0325 is ideal for users requiring high-precision RTD measurement with 4-wire support (e.g., power plants, chemical reactors) and compatibility with Honeywell or third-party control systems. For Siemens TIA users, SM 331 RTD Module is preferred (note: no 4-wire support); Allen-Bradley 1734-IR2 suits Rockwell systems (2 channels only).
2. Precautions:
   • Configure RTD type and wire configuration (2/3/4-wire) via DIP switches before installation—incorrect settings will cause measurement errors or failed lead wire compensation.
   • Use shielded twisted-pair cables for RTD wiring to minimize EMI interference, especially in long cable runs (e.g., >50m) where lead wire resistance is significant.
   • For 4-wire RTD configurations, ensure all four wires are the same gauge and length to maximize lead wire compensation effectiveness.
   • Perform annual calibration (per Honeywell recommendations) to maintain accuracy, especially in applications with strict regulatory requirements (e.g., food safety monitoring).
   • Verify the module’s IP20 rating—install only in enclosed control cabinets to protect against dust and moisture.
