The Honeywell FC-PSU-240516 is a fully redundant 24VDC power supply unit designed for mission-critical control systems within Honeywell’s Experion PKS Orion platform. This N+1 redundant power module delivers 30A continuous output with <0.5% voltage ripple, ensuring stable operation of safety instrumented systems (SIS) and distributed control units (DCUs). The FC-PSU-240516 features automatic load sharing and hot-swap capability, allowing maintenance without interrupting process operations.
As part of Honeywell’s Fault-Tolerant Power System (FTPS) family, the Honeywell FC-PSU-240516 supports dual 85-264VAC inputs with 94% conversion efficiency. Its integrated 4-stage harmonic filtering meets IEEE 519-2022 standards, protecting sensitive automation equipment from power quality issues. The module’s IP66-rated enclosure and -40°C to +85°C operating range make it suitable for offshore platforms and desert installations.

Key Features and Advantages:
Ultimate power stability: The Honeywell FC-PSU-240516 employs adaptive current balancing technology that automatically adjusts output between paralleled units within 10ms. This ensures ±1% current sharing accuracy even during 100% load steps.
Intelligent health monitoring: Built-in power quality analysis records voltage sag/swell events with 1ms resolution, while predictive algorithms estimate capacitor lifespan with 90% accuracy. Real-time data can be accessed via Experion Power Manager software.
Cybersecurity ready: Hardware-level firmware signature verification prevents unauthorized code modifications. The module’s isolated communication channel meets IEC 62443-4-1 requirements for industrial network security.
Application Areas:
The Honeywell FC-PSU-240516 is essential for:
- Oil & gas: Subsea control module power distribution
- Nuclear plants: Reactor protection system backup power
- Data centers: Critical process cooling system power
- Mining: Explosive atmosphere conveyor controls
In LNG liquefaction plants, this power supply simultaneously supports emergency shutdown systems, turbine control panels, and fire & gas detection systems while maintaining N+1 redundancy during monsoon-level humidity fluctuations.
