Honeywell 51303940-150 Fan Assembly
Product Manual:
Honeywell 51303940-150 (MU-FAN611) is a cabinet dual fan and alarm component of Honeywell UCN/TDC series DCS system, used to control forced heat dissipation and fault warning of the cabinet.
Model and alias: 51303940-150, alias MU-FAN611, UCN series dual fan alarm component.
Brand affiliation: Honeywell, specialized cooling spare parts for industrial DCS.
Core functions: dual fan forced cooling, fan failure/abnormal speed sound and light alarm, cabinet temperature control protection.
Power supply specifications: 85-132V AC, 47-63Hz, rated current 0.5A.
Fan parameters: Dual axis flow fan, with a speed of about 3100RPM and a single air volume of about 100CFM.
Alarm mechanism: Fan stop/low speed triggers sound and light alarm, and outputs dry contact alarm signal.
Physical structure: metal panel+dual fans+alarm circuit board, size approximately 222 × 111 × 44mm.
Weight: Approximately 1.2-3.22kg (slightly different versions).
Working environment: * * -40 ℃~+85 ℃ * * Wide temperature range, industrial grade anti-interference design.
Installation method: Cabinet panel embedded/screw fixed, compatible with standard cabinets such as Rittal.
Redundant design: Dual fans serve as backups for each other, and a single fan failure does not immediately shut down.
Protection features: overvoltage/overcurrent/reverse connection protection, fan stall detection, watchdog monitoring.
System adaptation: Honeywell DCS systems such as TDC 2000/TDC 3000/Export PKS/UCN.
Application scenarios: Cooling of industrial control cabinets in power plants, chemical, oil and gas, metallurgy, and other industries.
Spare parts attribute: Classic discontinued spare parts, mostly used for maintenance and replacement of old DCS systems.
The Honeywell 51303940-150 is designed with dual fan redundancy and integrated alarm to ensure stable heat dissipation of DCS cabinets. It is a key heat dissipation and safety component of Honeywell industrial control systems.
