Overview Manuals Specifications Applications Installation & Integration Operating Environment

Features:

  • Redundant Dual-Rotor Cooling Performance
  • Active Functional Safety Diagnostics
  • Robust Fault-Tolerant Electrical Design
The HONEYWELL FC-FANWR-24R utilizes two independently balanced high-performance fan units engineered onto a single industrial-grade frame. This dual setup ensures continuous active air movement inside high-density controller chassis, preventing localized heat pockets and maintaining stable ambient conditions for nearby Safety Manager modules even during extended heavy process loads.

Equipped with an advanced potential-free readback relay and dedicated bright green status LEDs, the HONEYWELL FC-FANWR-24R delivers live diagnostic metrics. If either of the internal fans falls below the safety threshold of 1,500 RPM due to mechanical fatigue or dust obstruction, the readback circuit immediately breaks to trigger system alarms.

The electrical interface of the HONEYWELL FC-FANWR-24R is optimized for high reliability, incorporating hardwired reverse polarity diode protection and an onboard 2A fuse. This rugged layout prevents upstream cabinet power disruptions during field faults, ensuring the unit withstands extreme industrial voltage tolerances from 12V up to 29V DC.

The FC-FANWR-24R HONEYWELL Dual Fan Cooling Assembly Kit with Speed Readback may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Safety Manager Cabinet Protection: Deployed directly inside Honeywell critical process control and emergency shutdown (ESD) enclosures to maintain safe operating temperatures for dense processor packs and communication modules.
  • High-Density I/O Rack Ventilation: Installed within Safety Universal I/O (RUSIO) and high-density termination setups to dissipate thermal loads generated by field loop currents and active barrier modules.
  • Legacy Hardware Renewal Projects: Utilized as the primary direct-swap spare part during plant modernization turnarounds to replace aging, worn out cooling units across older Safety Manager installations.
  • Harsh Distributed Control Environments: Applied in remote instrument enclosures, offshore oil platform control rooms, and petrochemical marshalling cabinets where active cooling verification is mandatory for remote diagnostic strategies.
  • Quick-Connect Terminal Modular Fitting: Employs a pluggable 4-pole screw mating system that allows operators to safely swap fan modules during live system operations without disturbing adjacent wiring.
  • Enclosure Chimney-Effect Placement: Typically integrated near top louvers or specific air ducts within Rittal TS cabinets to draw cool air up from the bottom of the enclosure and push heated air out.
  • Dedicated Enclosure Grounding Path: Features explicit structural metallic contact zones and grounding paths that must be securely bonded to the main cabinet ground busbar to ensure full ESD protection.
  • Unobstructed Air Vector Clearances: Requires careful layout mapping during cabinet assembly to guarantee that incoming wiring harnesses or dense field cabling do not block the high-volume 360 m³/hr intake grid.
  • Industrial Thermal Extremes: Extensively tested to maintain stable mechanical rotor speeds and flawless relay state operation under ambient conditions ranging from -30°C to +75°C.
  • Cabinet Power Architecture Tolerance: Accommodates standard unregulated industrial battery and power systems, operating reliably on any input voltage ranging between 12V and 29V DC.
  • Sealed Enclosure IP20 Protection: Built with an IP20 ingress protection profile, meaning it must be installed inside filtered, dust-controlled electrical rooms or sealed cabinets to prevent moisture damage.
  • Vibration and Industrial Mechanical Stress Shielding: Manufactured with reinforced structural mounting plates and ruggedized internal PCB solders to withstand the continuous low-frequency vibrations typical of heavy industrial heavy machinery areas.
Description
Engineered to meet the stringent demands of industrial safety environments, the HONEYWELL FC-FANWR-24R utilizes a heavy-duty dual-fan architecture mounted on a robust metal chassis, delivering high-volume airflow to prevent hot spots and safeguard high-density controller and I/O components from premature heat-induced failures.

The HONEYWELL FC-FANWR-24R integrates an onboard diagnostic circuit with a potential-free readback relay, providing automated real-time health monitoring that immediately alerts the Safety Manager system if either fan drops below optimal operational speeds, ensuring absolute system uptime.

Built to sustain continuous 24/7 manufacturing operations, the HONEYWELL FC-FANWR-24R combines energy-efficient 9.5W power consumption with an exceptionally wide operating temperature tolerance, ensuring reliable active ventilation in volatile localized cabinet climates without sacrificing component longevity.

Designed as a direct fit-and-forget component for modern safety system cabinets, the HONEYWELL FC-FANWR-24R simplifies cabinet infrastructure by offering clean field terminal connectivity and immediate status verification, ensuring compliance with rigorous functional safety design protocols.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does the HONEYWELL FC-FANWR-24R interface with Safety Manager diagnostics and I/O wiring?
The HONEYWELL FC-FANWR-24R utilizes a built-in potential-free dry contact that remains closed when both internal fans operate safely above 1,500 RPM. This contact is hardwired to a digital input channel or a cabinet fault loop. If either rotor fails or drops speed, the contact opens, prompting the Safety Manager logic to trigger a diagnostic alarm in the DCS.
What are the exact I/O terminal connections and pin allocation requirements for the HONEYWELL FC-FANWR-24R?
The HONEYWELL FC-FANWR-24R connects via a quick-disconnect 4-pole screw terminal block. Pin 1 is designated for +24 V DC main supply power, Pin 2 is the 0 V return line, and Pins 3 and 4 connect across the potential-free diagnostic readback loop. The terminal block supports up to 2.5 mm² wires to ensure stable current distribution.
What type of internal circuit depth and electrical overcurrent protection does the HONEYWELL FC-FANWR-24R feature?
The HONEYWELL FC-FANWR-24R contains an integrated board-level protection circuit consisting of a reverse polarity protection diode and a user-replaceable 2A slow-blow cartridge fuse (5 x 20 mm). If field power leads are swapped or a severe electrical surge occurs, the diode protects the fan electronics while the fuse safely isolates the unit.
Can the HONEYWELL FC-FANWR-24R readback contact handle high-voltage alarm loops or interposing relay coils?
No, the potential-free readback relay inside the HONEYWELL FC-FANWR-24R is specifically isolated for low-voltage safety instrumented loops, rated up to 50 V DC or 30 V AC. To guarantee contact integrity and prevent internal micro-welding, the total switched current must not exceed 0.5 A and the maximum contact switching load must remain under 10 W.
Are there any specific mounting orientation restrictions or airflow clearances for the HONEYWELL FC-FANWR-24R?
The HONEYWELL FC-FANWR-24R can be securely mounted in both horizontal and vertical positions within standard industrial racks or enclosure panels. Integrators must orient the assembly to pull air upwards to utilize natural chimney effect thermal currents, while maintaining a completely unobstructed clearance on both intake and exhaust faces.
