Product Model: 51303642-300 (Standard Number: 51303642300)

Brand: Honeywell

Product Category: TDC 3000 / TPS System Dual Node Fan Assembly

Applicable Systems: Honeywell TDC 3000 / TPS / UCN Distributed Control System (DCS) 

I. Product Overview

51303642-300 is a dedicated cooling component in the Honeywell TDC 3000 system, specifically designed to provide forced air cooling for TEC (Thermoelectric Cooler) or high-density processor nodes within the system cabinet. It integrates dual fans, intelligent temperature control, and overcurrent protection, ensuring the stable operation of the core control module in high-temperature and high-load industrial environments. It is a key component for the reliable operation of the TDC 3000 system.

III. Functional Features

1. Dual Fan Redundancy Design

Dual Fan Parallel: If one fan fails, the other continues to operate without risk of shutdown

Automatic Switching: Faulty fan automatically cuts power, system issues an alarm

Hot Swap: Supports online replacement of faulty fans (safe operation with power off)

Status Monitoring: Real-time upload of fan speed, temperature, and fault status to the system

2. Intelligent Temperature Control Speed Adjustment

Built-in Temperature Sensor: Real-time monitoring of node / cabinet temperature

Automatic Speed Adjustment:

≤ 35°C: Low-speed operation (energy-saving and low noise)

35°C～55°C: Medium-speed operation

≥ 55°C: Full-speed operation (maximum air volume)

Overheat Alarm: ≥ 65°C triggers system high-temperature alarm

3. High-Reliability Industrial Design

Long-life Bearings: Ball bearings, suitable for continuous 24-hour operation

Pre-Installed Dust Filter: Front-mounted detachable dust filter, easy cleaning and maintenance

Metal Reinforcement: Resistant to vibration and shock, suitable for industrial sites

Low-noise Optimization: ≤ 50 dB(A), compliant with workshop noise standards

4. System Compatibility

Fully Compatible: TDC 3000, TPS, UCN systems

Adaptable Nodes: TEC modules, PM processors, I/O racks

Plug-and-Play: Direct replacement of faulty fan components, no rewiring required

Status Feedback: Supports system DCS screen monitoring of fan status

IV. Typical Applications

TDC 3000 System Cabinet: Core Processor Node Cooling TEC thermoelectric cooling module: Forced air cooling for auxiliary heat dissipation

High-density I/O rack: Reduces module temperature rise

High-temperature workshop: For heat dissipation in chemical, metallurgical, and power control rooms

Upgrade of old systems: Replace aging fans to enhance system stability

V. Installation and Maintenance Tips

Installation: Install vertically to ensure smooth air intake and exhaust

Maintenance: Clean the dust filter every 6 months and check the fan speed annually

Fault: Single fan failure can be replaced online without system shutdown

Life: Suggested overall replacement every 5 years (preventive maintenance)

VI. Product Status
