Honeywell FC-FANWR-24R Cooling Fan Module

A cooling fan module specifically designed for industrial equipment (such as control cabinets and PLC systems), driven by a 24V DC power supply to ensure stable operation of equipment in high-temperature environments.

Equipped with intelligent temperature control, which automatically adjusts the fan speed according to the ambient temperature to reduce noise and power consumption (e.g., low-speed operation at low temperatures and full-speed operation at high temperatures).

The housing is made of fireproof materials, compliant with UL and CE certification standards, and has the ability to resist electromagnetic interference (EMI), adapting to complex industrial field environments.

Compatible with Honeywell's series of control platforms, it can be integrated with DCS and PLC systems to achieve remote monitoring and fault alarm.

Supports DIN rail or panel installation, with detachable terminal blocks for convenient on-site wiring and replacement; some models support hot-swapping to ensure system operation is not interrupted during maintenance.

The built-in or external NTC thermistor collects the ambient temperature in real time, converts the temperature signal into an electrical signal (such as resistance value change), and transmits it to the microprocessor after being converted into a digital quantity by ADC.

The microprocessor outputs a PWM (Pulse Width Modulation) signal according to preset thresholds (e.g., starting low speed at 40℃ and high speed at 50℃), adjusts the duty cycle of the fan drive circuit, and realizes speed control.

The power module converts 24V DC into the 5V/3.3V power required by internal chips, and drives the fan motor through MOSFET or relay, with overcurrent protection (automatically cutting off the output when the current exceeds the rated value).

The fan motor adopts a brushless DC (BLDC) design, featuring high efficiency and long service life (typical service life ≥50,000 hours), and supports forward/reverse rotation detection (some models) to ensure the fan operates normally.

Communicates with the host computer or controller through the RS-485 interface, uploads real-time temperature, fan status (operation/fault) and other data, and receives remote control commands (such as forced start/stop, speed setting).

Integrates hardware watchdog and overload protection mechanisms. When the fan is blocked, the power supply is abnormal, or the temperature sensor fails, it automatically triggers alarm signals (such as indicator light flashing, relay output).
