Advantages and Features

1. 1+1 Redundancy and Hot-Swappable Design

   HONEYWELL TK-PRS021 supports seamless 1+1 redundancy, where two modules operate in parallel to provide fail-safe power supply. The hot-swappable feature allows technicians to replace a faulty module without powering down the controller rack, eliminating unplanned downtime for critical processes like chemical batch production and oil refinery operations.

2. Wide Input Voltage Compatibility

   With dual AC/DC input support and a broad voltage range, HONEYWELL TK-PRS021 adapts to diverse power grid conditions, including voltage sags, surges, and temporary outages. This versatility makes it ideal for deployment in remote industrial sites with unstable power supplies.

3. High Precision Voltage Regulation

   Boasting ±0.5% output voltage accuracy, HONEYWELL TK-PRS021 ensures consistent power delivery to sensitive DCS components, preventing data corruption and control logic errors caused by voltage fluctuations. This precision is critical for maintaining process stability in high-precision applications like pharmaceutical manufacturing.

4. Real-Time Health Monitoring and Diagnostics

   HONEYWELL TK-PRS021 integrates with Honeywell Experion PKS diagnostic tools to provide real-time data on input/output voltage, temperature, and load status. The module triggers proactive alarms for potential faults, enabling predictive maintenance and reducing the risk of unexpected failures.

5. Robust Industrial Durability

   Built with industrial-grade components and EMI-shielded circuitry, HONEYWELL TK-PRS021 resists electrical interference from nearby motors and power equipment, maintaining stable performance in high-noise environments like steel mills and power plants. Its passive cooling design eliminates fan-related failure points, extending service life.

Application Cases

• Oil and Gas Refineries: HONEYWELL TK-PRS021 powers Experion PKS controllers and I/O modules in crude oil distillation units, ensuring continuous process control and safety system operation even during power grid fluctuations.
• Chemical Processing Plants: Integrated into reactor control systems, the module provides redundant power to critical temperature and pressure monitoring equipment, supporting uninterrupted batch processing of hazardous chemicals.
• Power Generation Facilities: Used in boiler control systems for thermal power plants, HONEYWELL TK-PRS021 ensures stable power supply to combustion control and emission monitoring modules, complying with strict environmental regulations.

Comparison with Competitors

• Redundancy and Hot-Swap Advantage: Unlike generic power supplies that require external redundancy controllers, HONEYWELL TK-PRS021 features built-in 1+1 redundancy and hot-swappable functionality, simplifying system design and reducing hardware costs.
• Honeywell Ecosystem Compatibility: Third-party power modules often lack full integration with Experion PKS diagnostic tools, limiting visibility into module health, whereas HONEYWELL TK-PRS021 provides real-time data for predictive maintenance.
• Voltage Regulation Precision: Competing modules typically offer ±1% voltage accuracy, while HONEYWELL TK-PRS021 delivers ±0.5% precision, ensuring optimal performance of sensitive DCS components.

Selection Recommendations and Precautions

Selection Recommendations

• Choose HONEYWELL TK-PRS021 for upgrading or expanding Honeywell Experion PKS DCS systems, especially in continuous production applications requiring zero downtime and redundant power supply.
• This module is ideal for industries such as oil and gas, chemicals, and power generation, where process interruption can lead to significant financial losses or safety hazards.

Precautions

• HONEYWELL TK-PRS021 is designed exclusively for Honeywell Experion PKS systems; do not use it with non-Honeywell DCS or PLC platforms without official compatibility verification.
• Ensure the module is installed by certified Honeywell technicians following the official wiring guidelines to avoid reverse polarity or overloading, which may damage HONEYWELL TK-PRS021 or connected DCS components.
• Use only licensed Honeywell Engineering Workbench software for configuration and firmware updates; unauthorized software may corrupt the module’s firmware and disrupt system operation.
