Advantages & Features

1. Multi-Protocol Fieldbus Support: HONEYWELL TP-FPW231 is compatible with both Foundation Fieldbus H1 and Profibus PA protocols, eliminating the need for separate power supplies for different fieldbus networks and reducing hardware complexity.
2. Redundant Power Delivery: The module supports 1:1 hot-redundant configuration, ensuring uninterrupted power to fieldbus segments even if a primary power supply module fails—critical for safety-critical applications (e.g., ESD systems).
3. Hazardous Environment Compliance: Certified to ATEX/IECEx Zone 2, HONEYWELL TP-FPW231 can be installed in explosive atmospheres (e.g., refinery process units) without additional enclosures, simplifying system design and installation.
4. Advanced Diagnostics & Surge Protection: Built-in overcurrent/short circuit protection and real-time voltage/current monitoring prevent damage to fieldbus devices, while surge protection (up to 2kV) safeguards against electrical transients in industrial environments.

Application Fields & Cases

1. Oil Refinery Fieldbus Network Power: A major oil refinery deployed HONEYWELL TP-FPW231 modules in a redundant configuration to power Foundation Fieldbus H1 networks in its crude distillation unit, supplying power to pressure/temperature transmitters and control valves. The redundant design prevented network downtime during a module failure, maintaining continuous process monitoring.
2. Chemical Plant Profibus PA System: A petrochemical plant integrated HONEYWELL TP-FPW231 into its Profibus PA network to power flow meters and level transmitters in a batch reactor area. The module’s Zone 2 certification allowed installation in the hazardous process zone, eliminating the need for remote I/O racks.
3. Power Plant Boiler Fieldbus Infrastructure: A combined-cycle power plant used HONEYWELL TP-FPW231 to power dual Foundation Fieldbus H1 segments in its boiler system, supporting gas analyzers and steam flow transmitters. The module’s diagnostic capabilities detected an overcurrent condition in one segment, alerting operators to a faulty transmitter before it caused network failure.

Selection Suggestions & Precautions

1. Selection Suggestions: HONEYWELL TP-FPW231 is ideal for Honeywell Experion PKS/Safety Manager users requiring multi-protocol fieldbus power with redundancy and Zone 2 compliance (e.g., refineries, chemical plants). For Emerson DeltaV users, Emerson’s Fieldbus Power Supply is preferred; Siemens SITOP Fieldbus Power suits Profibus PA-only networks with Siemens systems.
2. Precautions:
   • Configure output voltage (9-32V DC) to match the requirements of connected fieldbus devices (e.g., 24V DC for FF H1 devices) via the configuration software.
   • Use shielded, fieldbus-certified cables (e.g., Belden 3076A for FF H1) to minimize EMI interference and ensure compliance with fieldbus standards.
   • Limit the number of devices per segment to stay within the 500mA current rating (typically 16-32 devices per segment, depending on power consumption).
   • Install modules in a redundant configuration for safety-critical applications to eliminate single points of failure.
   • Verify ATEX/IECEx certification matches the hazardous zone classification (Zone 2 only; not suitable for Zone 1 areas).
