Honeywell FS-FANWR-24R Safety Manager Fan Tray Assembly

Product Overview

The Honeywell FS-FANWR-24R (also identified as FC-FANWR-24R) functions as the primary forced-air cooling solution for the Honeywell Safety Manager (FSC/SM) chassis. This specialized fan tray assembly maintains the thermal equilibrium of high-density processor and I/O racks, preventing localized heat buildup that can lead to logic solver degradation or premature component failure. We provide this unit as 100% Brand New Original stock, ensuring your SIL-rated safety systems operate within certified temperature parameters.

Technical Specifications

The FS-FANWR-24R features a robust mechanical design optimized for continuous 24/7 operation in critical infrastructure:

Engineering Advantages

• Targeted Heat Extraction: The FS-FANWR-24R utilizes high-static pressure fans to force air through densely packed I/O cards. This airflow removes stagnant heat pockets from the center of the chassis, extending the Mean Time Between Failures (MTBF) of adjacent processors.

• Low-Vibration Operation: Honeywell engineers this tray with precision-balanced fan blades and vibration-dampening mounts. This design prevents mechanical harmonics from transferring to the backplane, protecting sensitive electronic connectors from fretting corrosion.

• Slim Profile Integration: The 6cm height allows for easy integration into standard safety cabinets without sacrificing valuable rail space. It slides directly into the dedicated cooling slot, aligning perfectly with the system's intended convection paths.

• Redundant Cooling Support: In high-availability architectures, the FS-FANWR-24R integrates with the system's power distribution to provide continuous ventilation. Even in redundant configurations, this unit ensures that thermal limits remain within safe thresholds during peak processing loads.

• Plug-and-Play Maintenance: The unit features a standardized interface that allows for rapid replacement. This minimizes "Time-to-Repair" during scheduled maintenance intervals, keeping the Safety Instrumented System (SIS) fully protected.

FAQs

• Does the FS-FANWR-24R require an external power supply?

  No. The fan tray draws its 24VDC power directly from the Safety Manager backplane or power distribution bus once you slide it into the chassis. This ensures the cooling system starts automatically whenever the safety rack energizes.

• What are the consequences of operating a Safety Manager rack without this fan tray?

  Operating without forced ventilation significantly increases the internal temperature of processor modules. High heat can trigger thermal alarms in the diagnostic software and may eventually cause an unscheduled shutdown of the safety loop to protect hardware from permanent damage.

• How often should I inspect the FS-FANWR-24R?

  We recommend a visual inspection every six months to check for dust accumulation. Clear airflow remains critical for cooling efficiency. Replacing aged fan units with Brand New Original units every 3–5 years prevents bearing failure and maintains optimal RPM levels.

• Is this unit compatible with both FSC and Safety Manager systems?

  Yes. The FS-FANWR-24R fits the standardized chassis dimensions used across the Honeywell Fail Safe Control (FSC) and Safety Manager product lines, providing a universal cooling solution for these legacy and modern platforms.
