Product Introduction
Honeywell FC-FANWR-24R is a 24 V DC cabinet fan unit with readback, used to maintain airflow inside Honeywell control-system cabinets. Honeywell’s own 2025 System Hints newsletter specifically identifies this part number as the replacement fan assembly for applicable cabinets and recommends replacing the fan every 8 years of operation.
The assembly is built around two fans and a PCB on a mounting plate, with the readback circuit providing fan-status monitoring to the control system. Available technical listings identify a 24 V DC supply and 9.5 W power requirement for the assembly. This is a maintenance component, not a controller or I/O card, and its condition directly affects cabinet thermal management.

Honeywell FC-FANWR-24R
Application and Selection Notes
The main job is simple: keep the cabinet cool.
The unit is intended for Honeywell control cabinets where continuous airflow and fan-condition feedback are required. It is therefore relevant to maintenance of installed safety and process-control equipment, especially where loss of cabinet ventilation could increase internal temperature and shorten the service life of electronic assemblies.
One important point: FC-FANWR-24R is not a generic 24 V industrial fan. The readback function, mounting arrangement, dual-fan construction, and associated PCB make the assembly specific to the Honeywell cabinet architecture. Honeywell’s own maintenance guidance recommends periodic replacement rather than waiting for a failed fan alarm.
Advantages and Limitations
Advantages
- Dual-fan configuration provides cabinet airflow.
- 24 V DC supply suits Honeywell control-system power architectures.
- Readback circuit allows fan-condition monitoring.
- Factory-style mounting arrangement simplifies replacement.
- Clearly defined preventive-maintenance interval from Honeywell.
Limitations
- It is a cabinet cooling component, not a programmable control module.
- Exact mounting and feedback connections must match the existing installation.
- The two fans should not be substituted independently without confirming electrical and mechanical compatibility.
- Current market availability can vary because this is a legacy maintenance item.
Quality Inspection and Pre-Shipment Checks
- Incoming inspection: Verify manufacturer identification, part number, serial or assembly markings where present, fan condition, PCB condition, connectors, mounting plate, and visible signs of corrosion or overheating.
- Live test: Energize the assembly from a controlled 24 V DC source and verify both fans start correctly and the readback signal changes to the expected operating state. Record the result in a Test Report.
- Electrical checks: Check supply wiring, connector continuity, grounding where applicable, and fan current against the available technical reference.
- Configuration verification: Record the PCB identification and fan arrangement. Compare the replacement assembly with photographs of the original installation.
- Final QC: Photograph the nameplate and assembly, protect the unit against dust and impact, and package the fan blades and connectors carefully.
Test photographs and available Test Reports can be provided with the shipment when requested.
Technical Replacement Risks
Fan feedback mismatch. The assembly includes a readback function. A physically similar 24 V fan without the correct monitoring circuit may run but still generate a cabinet fan alarm.
Wrong fan voltage. Verify the actual system supply before energizing. This unit is specified for 24 V DC.
Airflow restriction. A new fan cannot compensate for a blocked filter, obstructed cabinet inlet, or heavy dust accumulation. Honeywell’s maintenance guidance specifically calls for checking dust and cabinet condition.
Mechanical orientation. Photograph the original airflow direction and connector routing. Install the replacement the same way.
And one practical rule: don’t wait until both fans stop. Honeywell recommends scheduled replacement at eight years of operation for the applicable cabinet application.
Purchase and Logistics Notes
For international procurement, describe the item as Honeywell FC-FANWR-24R, 24 V DC Fan Unit with Readback, dual-fan cabinet assembly. State the physical condition separately as New Original, New Surplus, Refurbished, or Repaired.
Before purchase, request confirmation of:
- Exact part number
- Assembly condition
- PCB identification
- Fan configuration
- Test status
- Warranty period
- Country of origin
- Gross weight and package dimensions
For export packing, use rigid cushioning around the fan housing and mounting plate. Protect the connector and PCB from ESD, moisture, and impact. Make sure the commercial invoice, packing list, and product label show the same part number.
Quick Conclusion
- FC-FANWR-24R is a Honeywell 24 V DC cabinet fan unit with readback monitoring.
- The assembly uses two fans and PCB 07209 on a mounting plate.
- Supplier technical data lists approximately 9.5 W power consumption and 360 m³/h airflow for the complete assembly.
- Honeywell recommends replacing the applicable fan assembly every 8 years of operation.
- For replacement, match the fan assembly, readback circuit, mounting arrangement, and cabinet application rather than sourcing by voltage alone.
FAQ
What is the Honeywell FC-FANWR-24R?
It is a 24 V DC cabinet fan unit with readback monitoring used in Honeywell control-system cabinets.
How many fans are included?
The assembly contains two fans mounted together with PCB 07209.
What is the power requirement?
Available technical records specify 24 V DC and 9.5 W for the assembly.
Why does the readback function matter?
The readback circuit allows the control system to monitor fan operation. A generic replacement fan may provide airflow but fail to provide the expected status signal.
How often should it be replaced?
Honeywell’s October 2025 System Hints newsletter recommends replacement every 8 years of operation for the applicable fan assembly.
What should be checked before ordering?
Verify the complete part number, cabinet application, fan arrangement, readback connection, mounting plate, supply voltage, and physical condition of the replacement unit.
