Product Description

Model Number Interpretation

• 45C: Prefix for Reliance AutoMate 45C-series control components.

• 332: Designates a 10-slot dual fan module.

• No suffix: Original hardware revision; no common lettered variants (A/B/C/D) for this part.

Technical Specifications

• Input Voltage: 120 VAC, 50/60 Hz

• Current Draw: 0.36 A

• Configuration: Dual fans (parallel airflow)

• Rack Compatibility: AutoMate 10-slot 45C31x series racks

• Slot Occupation: 1 slot (replaces a blank filler panel)

• Operating Temperature: 0°C to +55°C

• Dimensions: ~96.5 × 70.5 × 56.5 mm

• Weight: ~0.55 kg

• Protection: Overcurrent fuse, fan fail alarm (via backplane)

Interface & Installation

• Mounting: Side-insertion into standard AutoMate rack slots, secured with screws.

• Backplane Connection: Edge connector for power and fan status signaling.

• Front Panel: No user controls; integrated status LED (power/fan ok).

• Airflow: Draws cool air from front, exhausts rear; aids convection for adjacent modules.

Core Functions

• Delivers forced-air cooling to prevent overheating in 10-slot racks with high power dissipation.

• Maintains optimal temperature for CPU, power supply, and I/O modules during continuous operation.

• Monitors fan operation and reports faults to the PLC backplane for system diagnostics.

• Reduces thermal stress on components, extending service life of legacy systems.

Application Scenarios

• Cooling upgrade/replacement for 10-slot AutoMate 30/40 series PLC racks.

• Maintenance of legacy industrial systems (manufacturing lines, process control, water treatment, metallurgy).

• High-density I/O racks where passive cooling is insufficient.

• Critical control panels requiring reliable thermal management for long-term operation.

Usage & Maintenance

• Installation: Power off the rack, remove the blank panel, insert 45C332, and tighten screws.

• Wiring: No external wiring; power is drawn directly from the backplane.

• Routine Check: Verify fan rotation and status LED monthly; clean dust from fan blades quarterly.

• Replacement: If a fan fails, replace the entire module (fans are not field-replaceable).

• Safety: Disconnect AC power before removal to avoid electric shock.
