Honeywell FC-FANWR-24R Cabinet Cooling Fan Assembly

Description

Honeywell FC-FANWR-24R Cabinet Cooling Fan Assembly

The Honeywell FC-FANWR-24R is a 24 V DC cabinet cooling fan assembly with integrated speed readback and alarm monitoring. Built with dual ebm-papst ball-bearing fans, it provides forced-air ventilation for Honeywell Safety Manager and Series C industrial control cabinets.

Technical Specifications

• Model & Prefix: FC-FANWR-24R (Conformal Coated version of FANWR-24R / FS-FANWR-24R)

• Nominal Operating Voltage: 24 V DC (12 V DC to 29 V DC operating range)
• Power Consumption: 9.5 W total for the complete assembly
• Airflow Capacity: 360 m³/hr (211.8 CFM)
• Nominal Speed: 3,200 RPM (minimum 1,500 ± 100 RPM required to hold readback contact closed)
• Acoustic Noise: 52 dB
• Readback Alarm Contact: Relay output rated up to 300 V DC / 240 V AC, 0.5 A max, 10 W max
• Service Life: 85,000 hours at 40 °C (104 °F); 37,500 hours at 75 °C (167 °F)
• Operating Temperature: -30 °C to +75 °C (-22 °F to +167 °F)
• Ingress Protection: IP20
• Dimensions & Weight: 391 mm × 142 mm × 51 mm (15.4 in × 5.59 in × 2.01 in); 1.7 kg (3.75 lbs)
• Approvals: CE, UL, FM

Key Advantages

• Active Speed Readback & Alarming: Monitors fan rotation speed and opens a dry readback contact if speed drops below 1,500 RPM, alerting operators before cabinet temperatures climb.
• Conformal Coating (FC- Prefix): Protects internal monitoring electronics against humidity, dust, and corrosive industrial gases.
• High Airflow Capacity: Moves 360 m³/hr (211.8 CFM) to prevent thermal hotspots across densely packed I/O modules and power supplies.
• Long Industrial Service Life: Ball-bearing fan construction delivers up to 85,000 hours of continuous operation at 40 °C.

Important Usage & Installation Precautions

• No Reverse Polarity Protection: The 24 V DC power input lacks reverse polarity protection—verify positive and negative terminal wiring before energizing to avoid permanent damage.
• Proper Terminal Torque & Tools: Strip wires to 7 mm and tighten screw terminals to 0.4–0.5 Nm using a DIN 5264 (0.6 × 3.5 mm) flathead screwdriver.
• Readback Contact Load Limits: Keep alarm circuit loads within 0.5 A and 10 W so the internal readback relay contacts don’t weld or fail.
• Cabinet Enclosure Requirement: Rated IP20, so it must be mounted inside a protected control cabinet rather than exposed to outdoor or washdown environments.

Applications

• Safety Instrumented Systems (SIS): Standard cabinet cooling unit for Honeywell Safety Manager and Fail Safe Controller (FSC) racks.
• Distributed Control Systems (DCS): Used in Honeywell Experion PKS / Series C enclosures to maintain safe ambient temperatures for I/O cards and controllers.
• Harsh Process Plants: Deployed in oil & gas refineries, chemical plants, and power generation facilities where continuous thermal monitoring is mandatory.
